Computed Radiography (CR)


Computed radiography (CR) is an imaging technique that creates diagnostic pictures of the interior organs and bone structure of the body. The method uses a digital imaging plate to take X-ray pictures, which are subsequently processed by a computer into diagnostically useful images.

Process of CR

  • Radiation is emitted through the body by an X-ray machine while the patient is lying on an X-ray table.
  • A digital imaging plate is used to capture the image instead of conventional X-ray film. The imaging plate is constructed from a substance that can absorb X-ray energy and later release it when subjected to laser light.
  • The body portion being imaged is positioned behind the imaging plate, which is then exposed to radiation from the X-ray equipment as it passes through the body.
  • The imaging plate stores the radiation’s energy before being taken out of the machine and placed in a specialized scanner.
  • The imaging plate’s stored energy is released by the scanner’s laser, creating a digital image of the bodily portion that was imaged.
  • After that, a computer processes the digital image to create a high-quality image that can be utilized for diagnosis.

One benefit of CR technology is that it enables several images to be acquired without requiring the imaging plate to be changed. This reduces the quantity of radiation exposure to the patient by allowing for the collection of many images of a body part with a single radiation exposure. The ability of CR-created digital pictures to be easily stored and sent electronically is another benefit that makes it simpler for healthcare practitioners to access and exchange patient data. Additionally, the brightness, contrast, and zoom of the digital images can be changed, enabling a more in-depth examination of the body portion being photographed.

Need for CR in industries

Non-destructive testing (NDT) is a common use for computed radiography (CR), which is not merely employed in medical settings. In the manufacturing sector, CR is used to inspect castings, welds, and other components. In industrial applications, CR has a number of benefits over conventional film-based radiography, including:

  • CR systems are capable of detecting minor flaws in materials and structures because they are more sensitive than conventional film-based systems.
  • Since digital images created by CR may be viewed right away, decision-making and inspection procedures can be carried out more quickly.
  • CR does not require the processing of films, which lowers the cost of inspection and does not require the use of hazardous chemicals.
  • Imaging plates for CR can be used again, reducing waste and inspection costs.
  • The ability to modify contrast, brightness, and magnification on digital images created by CR enables a more thorough investigation of flaws.

Cracks, porosity, inclusions, and other material irregularities that could influence the final product’s quality and safety are all detected with CR in industrial applications. This is significant in sectors like construction, oil and gas, aerospace, and automotive where reliable operations depend on strong structures and materials.

Efficiency compared to other techniques

By enabling quicker picture acquisition, processing, and interpretation, computed radiography (CR) outperforms conventional film-based radiography. The use of digital imaging technology by CR allows for the creation of high-quality images that can be viewed instantly on a computer screen, doing away with the necessity for processing film and the holding procedure for developing photographs. Furthermore, as CR utilizes reusable image plates rather than pricey, fixed detectors, it is more effective than other digital imaging techniques like digital radiography (DR). This lowers the need for regular equipment changes and makes CR a more affordable alternative for imaging equipment. Furthermore, CR has a wider dynamic range than other imaging technologies, allowing it to record images with a wider variety of brightness and contrast levels. This enables the photos to be more clear and detailed, making it simpler for inspectors and healthcare professionals to find and identify issues and flaws.

Applications of CR

Computed radiography (CR) has several uses in a variety of industries, including industrial, dental, and medical imaging. To identify and track illnesses like fractures, lung infections, and malignancies, CR is frequently utilized in medical imaging. Additionally, it aids in the early detection of breast cancer during mammography. Dental cavities, periodontal disease, and jaw issues can all be identified with CR in dental imaging. Non-destructive testing (NDT) in industrial imaging is frequently used to inspect and assess materials and structures. It is employed to find flaws and irregularities in a variety of materials, such as metals, composites, and ceramics. This is significant in sectors like construction, oil and gas, aerospace, and automotive where reliable operations depend on strong structures and materials. Additionally, CR is employed in the study and analysis of historic artifacts and works of art without endangering them in the fields of archaeology and art conservation. It is used to identify materials and structures in historical artifacts as well as to find elements that are hidden beneath the surface of paintings, like brushstrokes.

Scope and significance of CR

Computed radiography (CR) is widely used and important in both industrial and medical imaging. In addition to inspecting and evaluating building materials and structures, it is essential for the diagnosis and treatment of illnesses and ailments. A safe and efficient imaging technique, CR technology has improved to the point where it is now able to obtain high-quality images while minimizing radiation exposure. The development of CR technology has allowed for the acquisition of high-quality pictures while reducing radiation exposure to patients and staff. Healthcare practitioners and manufacturers can access and share patient information and inspection reports more simply since the digital images created by CR are simple to save and communicate electronically.

In conclusion, Computed Radiography (CR) is a digital imaging technology used to create diagnostic images of the internal anatomy of the body. Compared to traditional X-ray imaging, CR has a number of advantages, such as the capacity to capture multiple images with a single exposure, the ease with which digital images can be stored and transmitted, and the capacity to manipulate digital images for a more in-depth analysis.
