|How images are obtained|
THE FLUOROSCOPY UNIT
The patient lies on a specialized table between the x-ray generator and the detector. The generator produces an x-ray beam which travels through the patient towards a specialized detector called the image intensifier.
The image intensifier absorbs the transmitted x-rays and emits part of the absorbed energy as light photons. Through a sophisticated process, the number of light photons emitted is amplified and they are converted into a digital image. This is then displayed live on a tv monitor.
The physician observes the images on the monitor live, as the study is being performed.
