Pulsed Fluoroscopy - Video Lesson

Host fluoroscopy is one of the most effective technologies for reducing patient dose without herding image quality. When used correctly, dose reductions can be as much as tenfold. In continuous fluoroscopy, the x-ray tube emits exposures continuously as long as the floral switch is engaged. This exposure is recorded by an image receptor at a rate of thirty frames per second. Because of this continuous exposure, Miller amperages are kept very low in order to protect the patient from over exposure and the x-ray tube from excessive tube heating. Post fluoroscopy allows us to pulse the x-ray exposure in rapid succession. Think of it as a strobe light. If we pulse at a rate of twenty per second or more, the image pulsing is typically not noticeable to the human eye because it cannot
