Image Distributor This visual output image is then sent through a series of lenses in the image distributor to a video camera or a charged-coupled device (CCD). Cardiology department, SVCMC
Control of the X-ray output Within the image distributor, a partially silvered mirror or prism - to a photodetector. Information from photodetector-to the generator to control the output Exposure is a function of the number of electrons made into X-rays (the mA) times the maximum voltage across the X-ray tube (kVp) times the pulse width (the length of time the X-rays are sent per frame). Too high kVp -washed-out image Too high mA-excessive scatter radiation Too high pulse width-blurring of image. Cardiology department, SVCMC
