Computed Radiography

Computed Radiography

Is the most advanced equipment to diagnose a disorder and the process that produced radiographs are also very good,Computed Radiography (CR) uses very similar equipment to conventional radiography except that in place of a film to create images, the imaging plate (IP) made of photostimulable phosphor used. Imaging plate is placed in a special cassette and placed under the body or object to be examined and x-ray exposure is made. Therefore, instead of using exposed film into a darkroom for developing in chemical tanks or automatic film processor, the imaging plate is run through a special laser scanner, or a CR reader, which reads and digitizes the image. Digital image can then be viewed and enhanced using software that has functions very similar to other conventional software digital image processing, such as contrast, brightness filtration, and zoom.
Computed radiography (CR) is often distinguished from Direct Radiography (DR). CR and DR have many similarities. Both CR and DR use a medium to capture x-ray energy and both produce a digital image that can be enhanced for soft copy diagnosis or further review. Both CR and DR can also present an image within seconds of exposure. CR generally involves the use of a cassette that houses the imaging plate, similar to traditional film-screen systems, to record the image whereas DR typically captures the image directly onto a flat panel detector without the use of a cassette. Image processing or enhancement can be applied on DR images as well as CR images due to the digital format of each. There are many different types of DR detectors in use in medicine and industry. Each type has its own merits and distinctions and may be applied to certain imaging requirements based on these attributes.
