Differences Between X-Rays and Digital Radiology

Common functions of both traditional X-rays and digital radiography include image detection, image capturing, and image data storage. During a radiographic procedure, an X-ray beam passes through an individual&#;s body. Some of the X-rays are absorbed by the internal body structure. The other X-rays are transmitted to a detector, such as film or a digital detector, forming a pattern that is recorded for future evaluation.

The primary differences between traditional X-rays and digital radiography are as follows:

• Traditional X-rays use film to capture images of internal structures in the body.
• In digital radiography, digital detectors instantly produce a digital radiographic image and store the images separately on a digital medium such as a computer.

Digital radiography makes it easy for images to be accessed electronically by radiographers, doctors, and other medical professionals via electronic health records (EHRs) or devices that store patient information.

It can be categorized into two types:

• Computed radiography (CR) works through an indirect process. It replaces traditional film used in traditional radiography with an imaging plate (IP). The information is then transferred over to a computing device for analysis.
• Digital detector array radiography (DDA) is also known simply as digital radiography, which uses a digital detector array or flat panel detector to convert X-rays directly into a digital image.

Digital technology sits at the center of digital radiography. This advanced form of X-ray inspection has become prominent in the medical imaging field over the past decade. New advancements continue to transform the field of radiology. For example, applications such as:

• Virtual reality and augmented reality to create immersive training for future radiology professionals
• Deep mind to reduce false results for cancer screening
• Cardiac MRI segmentation to deliver real-time diagnosis
• Augment intelligence to automate mundane manual tasks

AI-Aided X-Ray Interpretation

With advancements in computer vision, machine learning (ML), artificial intelligence (AI), and deep learning algorithms, the field of radiology has made huge strides in analyzing and interpreting imaging data. Through AI-aided X-ray interpretation, radiology professionals can improve the quality of patient care by speeding up and improving the accuracy of the diagnosis and treatment of injuries and diseases.

AI-aided X-ray interpretation works as follows:

• Using algorithms, it analyzes data and images at high speed from public and proprietary medical databases.
• It then compares images with previous findings to identify patterns and anomalies.

Benefits of AI-aided X-ray interpretation in diagnostic imaging include the following:

• Faster tracking of crucial information for diagnosis
• The ability to prioritize critical cases better
• Reduction of errors in reading electronic health records (EHRs)

Use Cases for AI-Aided X-Ray Interpretation

AI-aided X-ray interpretation has advanced over the last several years, especially regarding chest radiography, which is the most common diagnostic imaging examination in emergency departments. It continues to advance in many areas. Below are a few examples:

• AI-aided X-ray interpretation was used to help diagnose COVID-19. According to a European Radiology study, AI-assisted chest X-ray assessments helped radiologists differentiate COVID-19-positive from COVID-19-negative patients and improved the precision of diagnoses from 65.9% to 81.9%.
• A study published in JAMA found that AI algorithms performed as well as radiology residents when making preliminary interpretations of chest radiographs. The findings of the study suggest that AI can therefore improve radiology workflows, strengthen overall accuracy for more precise diagnoses, help address issues with resource scarcity, and lower healthcare costs.

Dual-Energy Imaging

Dual-energy imaging is a type of digital radiography, specifically computed tomography (CT). CT, also known as computed axial tomography (CAT), works this way:

• It uses a standard X-ray tube that produces X-ray beams that pass through the body at multiple angles and are captured by digital detectors.
• A computer then assembles the captured data to make cross-sectional images of the body that resemble &#;slices.&#;

A dual-energy CT scanner works similarly, but it also uses a second, lower-voltage X-ray tube in addition to the standard X-ray tube. The process of using two different X-ray energy sources of varying power provides advantages over standard CT because it produces clearer images for detecting lesions and abnormalities in a faster time.

In some cases, radiology professionals use substances known as contrast agents to aid in imaging. For example, iodine-based contrast is a commonly used agent that allows for examining blood vessels. A dual-energy CT scanner can detect the iodine more clearly than a standard CT scanner, producing more detailed images that can help improve diagnosis.

Use Cases for Dual-Energy Imaging

The concept of dual-energy imaging is not new. Research going as far back as the s and s demonstrated the advantages of dual-energy technology in improving tissue characterization. However, the time required for data acquisition was extensive, limiting dual-energy imaging&#;s usability for diagnostic imaging.

Today, new technology with faster processors allows for more rapid data acquisition and analysis, increasing the adoption of dual-energy imaging in the medical community.

Dual-energy imaging may be used for the following use cases:

• To produce better images of blood vessels
• To reduce the number of examinations a patient has to undergo
• To detect abnormalities in the body, for example detecting what type of kidney stone is present in a patient
• To improve image quality if a patient has metal inserts in their body structure
• To produce images that are well-designed for advanced 3D reconstruction and visualization of structures

Tomosynthesis

Tomosynthesis, an advanced type of digital mammography approved by the Food and Drug Administration (FDA) in , goes by many names, including 3-D mammography, breast tomosynthesis, and digital breast tomosynthesis (DBT).

Sometimes, the flat images produced by conventional 2D mammography make it difficult for radiologists to detect cancer, including creating areas in the pictures that appear abnormal. This often leads to patients getting called back for additional tests.

Tomosynthesis helps to avoid this using a different imaging approach. It creates multiple images of the breast using both 2D and 3D-like pictures, which are sent to a computer that uses algorithms to assemble the pictures, giving a more complete view of a patient&#;s breasts.

 Use Cases for Tomosynthesis

Tomosynthesis is a type of digital radiography that offers several benefits. Here are some statistics that highlight the advantage of tomosynthesis:

• Johns Hopkins Medicine reports that tomosynthesis can detect 41% more invasive cancers.
• According to Stanford Health Care, tomosynthesis reduces false positives by approximately 15%.
• A study published in European Radiology reveals that radiologists can improve cancer detection and reduce the time to read images with an AI reading support system.

Tomosynthesis can increase accuracy overall, especially when combined with conventional mammography.

Additional benefits for radiology professionals and patients include:

• Detection of breast cancer in the early stages or in patients not showing any symptoms
• Greater accuracy for breast cancer screening for people with dense breasts
• Identification of tumors that traditional mammograms can miss
• Reduction of callbacks and false-positive results

Computer-Aided Diagnosis

Computer-aided diagnosis (CAD) sits at the intersection of medicine and computer science. This form of digital radiography technology is designed to facilitate diagnostic decisions by medical experts.

Diagnostic imaging techniques, including X-ray, MRI, CT, and ultrasound diagnostics, provide essential data for radiologists to analyze and evaluate. In most cases, and because of the urgency of finding out the results, radiologists have to read images in a relatively short amount of time.

Types of CAD include computer-aided detection (CADe) and computer-aided diagnosis (CADx).

• Computer-aided detection (CADe): Marks areas of images that appear abnormal to reduce the chances of missing pathologies and to spotlight anomalies.
• Computer-aided diagnosis (CADx): Provides support for assessing and classifying pathologies, such as tumors and lesions, presented in medical images.

Use Cases for Computer-Aided Diagnosis

CAD has been a mainstay in the medical community for many years. The earliest versions of CAD relied on manual engineering and user domain expertise.

Newer approaches to building knowledge in CAD include the use of AI and machine learning. These intelligent systems also process large volumes of complex clinical data to create new knowledge that will enable them to improve diagnostic performance.

CAD software is used in a wide range of medical applications to help radiologists interpret medical images and make more accurate diagnoses. The most common medical applications include breast cancer detection and identification of pulmonary nodules that could cause lung cancer. CAD is also commonly used in the detection and diagnosis of:

• Colon cancer
• Prostate cancer
• Bone metastases
• Coronary artery disease
• Alzheimer&#;s disease
• Diabetic retinopathy

Automatic Image Stitching

Image stitching in digital radiography, the process of putting together smaller images to form a larger one, is used in various fields. For example, a satellite can take pictures of Earth&#;s surface, but its range is limited. It can take a picture of the topography of a region in the United States, but not of the whole country. Image stitching leverages intelligent technology to put together the individual images of regions to create a large topographic map of the U.S.

Similarly, in medical applications, a digital radiology scanning system can scan parts of the human body, but not the whole body all at once. If radiology professionals want to see a picture of a patient&#;s whole bone structure to look for anomalies that are indicative of potential medical issues, they can use image stitching technologies to &#;stitch&#; together images of different areas of the body.

Other terms used for image stitching include image registration and image mosaicking. Medical image stitching, by transforming two or more sets of imaging data into one coordinate system, plays a central role in medical robotics and intelligent systems from diagnostics and surgical planning to real-time guidance and post-procedural assessment.

Automatic image stitching is the process of stitching together multiple images without having to have a human intervene in the process. Using AI and ML algorithms, automatic image stitching overlaps regions of the same area to create a panoramic image that enables doctors to diagnose a disease in cases where a single scan does not provide an entire view of the area being investigated.

Use Cases for Automatic Image Stitching

Automatic image stitching can be applied medically in various ways. For example, the stitching of images can allow surgeons to do preoperative planning for surgeries such as leg alignment operations. Additionally, health professionals can see an entire image of a patient&#;s spine to diagnose scoliosis.

Recent studies offering insight into use cases for automatic image stitching include:

• A recent article in the Sensors journal published on MDPI points out how a panoramic stitching algorithm used in cone beam computed tomography reduced the need for patients to reposition themselves when images are being taken.
• An article in Scientific Reports notes that image stitching can be used to bring together different images of a single area for comparison purposes. For example, scans taken at different times can help to determine the growth of a tumor or determine the effects of surgery.

Digital Mobile Radiography

Digital mobile radiography equipment has wheels and is designed for easy transport in healthcare settings, such as hospitals, where it can be moved to a patient&#;s bedside. For example, patients with limited mobility following surgery can get imaged by a mobile X-ray unit to help the surgeon determine the outcome of the surgery. The ease of mobility of digital mobile radiography equipment makes it simpler to disinfect.

Digital mobile radiography equipment is a critical tool in digital radiography to help doctors assess and determine the condition of patients before sending them off to more advanced imaging techniques. For example, during the COVID-19 pandemic, hospitals have experienced high volumes of patients who needed diagnostic imaging. Digital mobile radiography units have been used as an essential triaging and screening tool for assessing the lung conditions of patients.

Use Cases for Digital Mobile Radiography

Digital mobile radiography equipment has many clinical diagnostic applications. Here are a few examples.

• Digital mobile radiography equipment allows patients who cannot be moved to a radiology department to get chest radiography.
• Because of its unique size, digital mobile radiography equipment can be positioned within tight spaces and between beds and other equipment, such as in surgical or endoscopic suites.
• According to a study published in BMC Health Services Research, digital mobile radiography equipment can be used outside of the hospital, including in nursing homes for the elderly, group dwellings for people with intellectual disabilities, and shelters.

NDE, an important technique of quality assurance, spans methodologies including ultrasonic, magnetic particle, eddy current, and last but not least, Radiographic Testing.

Radiographic Testing (RT), an integral facet of NDE inspection services, harnesses ionising radiation to probe material internals without compromise, ensuring structural integrity.

The rise of Digital Radiography in non-destructive evaluation (NDE) signifies a quantum leap in precision, augmenting imaging capabilities and data analysis in this domain.

Amidst this metamorphosis, the role of radiographic inspection services remains pivotal, safeguarding structural reliability.

These NDE Techniques and Technologies, inclusive of radiography and other methods, stand as a factor that ensures the longevity and safety of industrial components through non-destructive examination.

Principles and Working Mechanism

Understanding X-ray and Gamma-ray Sources

Radiographic Testing hinges on the utilisation of X-rays and gamma rays as primary sources. Both emerge from the electromagnetic spectrum, offering unique properties vital for Non-destructive Examination (NDE) techniques.

X-ray Generation

These high-energy electromagnetic waves are produced within an X-ray tube.

The process involves accelerating high-speed electrons towards a target material, typically tungsten. Upon collision with the target, the electrons release energy in the form of X-rays.

This mechanism creates photons with sufficient energy capable of penetrating materials for inspection purposes in NDT (Non-destructive Testing).

Gamma-ray Origins

Unlike X-rays generated in tubes, gamma rays arise from the decay of radioactive isotopes such as iridium-192 or cobalt-60.

These isotopes spontaneously emit gamma radiation during their natural decay process.

The emitted gamma rays possess high energy levels capable of deeply penetrating materials, making them valuable in NDE technology for examining thicker or denser components.

Both X-rays and gamma rays offer distinct penetration capabilities, allowing inspection of materials with varying densities and thicknesses, a critical aspect in NDE Inspection.

These sources provide the means to capture internal structural details without causing damage, facilitating comprehensive Non-destructive Examination Techniques essential across diverse industries.

Interaction of Radiation with Materials

Attenuation Process

Absorption:

When X-rays or gamma rays penetrate a material, they collide with atoms, causing a reduction in their energy as they transfer some energy to the atoms.

The extent of this absorption depends on the material's density and thickness.

Scattering:

As radiation interacts with the material's atoms, some photons are deflected from their original path, altering their trajectory.

This scattering phenomenon impacts the overall intensity and direction of the transmitted radiation.

Formation of Radiographic Images:

Attenuation-based Contrast

Differential Attenuation:

Within the material, areas with varying density or thickness attenuate X-rays or gamma rays differently.

Regions with higher density or thickness absorb more radiation, resulting in reduced exposure on the detector.

Contrast on Images:

The differential attenuation creates variations in exposure levels on the detector.

Darker areas on the radiographic image represent regions where more radiation was absorbed due to higher density or thickness. Conversely, lighter areas indicate less absorption due to lower density or thickness of the material.

Understanding these intricate interactions between radiation and materials is pivotal in Radiographic Inspection services, providing insights into the non-destructive examination process by interpreting radiographic images to identify defects or abnormalities accurately.

Equipment Used in Radiographic Testing

In the realm of radiographic testing, the pivotal equipment includes X-ray and gamma-ray machines, integral to Non-destructive Testing (NDT) Techniques, and industrial inspection for NDE (non-destructive examination) purposes.

X-ray Machines

Industrial X-ray Machines These instruments encompass an X-ray tube emitting high-energy photons directed at the test material.

Through the acceleration of electrons toward a target, the tube generates X-rays, crucial in NDT radiography and Industrial Inspection.

Gamma-ray Machines

Employing a sealed Radioactive Source, these machines emit gamma rays, typically using cobalt-60 or iridium-192.

These high-energy gamma radiations serve as fundamental tools in NDE techniques for radiographic testing.

Shielding and Collimation

Both X-ray and gamma-ray machines necessitate shielding mechanisms and collimation to precisely control and focus the emitted radiation.

These safety measures ensure the directed and safe application of radiation onto the test material, vital in industrial inspection for radiographic testing.

The utilization of X-ray and gamma-ray machines in Radiographic Testing, whether for digital radiography in NDT or conventional techniques, demands stringent adherence to safety protocols.

When exposed to radiation, the film reacts, creating a latent image that requires chemical processing.

This image development process involves various chemical baths, eventually unveiling the Radiographic Image.

While this method has been a cornerstone in NDT (Non-destructive Testing), it's relatively time-consuming compared to digital methods.

Digital Detectors

The advent of digital technology has introduced Computed Radiography (CR) and digital radiography (DR) systems.

These modern detectors directly convert the radiation interaction into digital signals.

CR systems use photostimulable phosphor plates that capture radiation and store it temporarily.

When scanned, these plates release the stored energy as light, which is then converted into digital signals for image creation.

DR systems, on the other hand, deploy digital sensors that capture radiation directly, converting it into immediate digital images.

The transition to digital detectors in radiographic inspection services has revolutionized NDE Technology.

Digital systems offer significant advantages, including real-time imaging, immediate results, enhanced image manipulation, and easier archiving.

This shift towards digital detectors has streamlined Non-destructive Examination Methods, improving efficiency and accuracy across various industries relying on NDT.
