Pulsed Fluoroscopy and Frame Averaging - Video Lesson

Hey, everybody. Just a warning, this video contains flashing lights. This lesson discusses pulsed and intermittent fluoroscopy and frame averaging. Both pulsed and intermittent fluoroscopy impact patient dose while pulsed fluoroscopy and frame averaging impact the quality of the fluoroscopic image. During continuous fluoroscopy, the X-ray beam is on continuously while foot pedal or hand exposure switch is activated, which can cause a high patient dose. This exposure is recorded at thirty pulses per second. Pulsed fluoroscopy is a mode on a fluoroscopic system that pulses the X-ray beam on and off at specific intervals, which reduces the exposure rate to set number of pulses per second, such as three point seven five, seven point five, and fifteen. Let's take a look at a graph and discuss three characteristics of x-ray pulses. Pulse height, pulse width, and pulse interval. Each bar on the graph represents a pulse, and the height and width of each bar is determined by
