Abstract

Scatter radiation in diagnostic radiology is recognized as an agent that adds noise to the imaging system and increases patient dose. A prototype computed radiography (CR) system by General Electric uses a highly collimated, 1.5 mm FWHM, pulsed fan-beam of x-rays, good geometry and well collimated xenon gas detector array to virtually eliminate scatter radiation resulting in high contrast sensitivity and low patient dose. The detectors with their high signal-to-noise ratio, wide dynamic range and large x-ray quantum efficiency provide added benefit in terms of wide latitude and reduced dose to the patient. The CR system is found to use radiation more efficiently than film-screen-grid standard radiography systems for imaging low-contrast objects in parts of the body such as abdomen.
