When we use the term frame rate, we will be speaking more Rate, we are referring to the output of the fluoroscope, specifically the Pulsed radiation, the distinction becomes meaningful. Output rate of the fluoroscope and the rate of image display on the monitor or on Historically, the term frame rate was used generically toĭescribe the number of images that were generated per second in aĬontinuous fluoroscopy, there is no meaningful distinction between the image Pulse Rate Versus Frame RateĪn important terminological issue to parse out is theĭifference between pulse rate and frame rate. New generation fluoroscopy offers anĪlternative, where the radiation beam can be delivered via small packets calledĭelivered per second can be specified, and deciding on what pulse rate to use requiresĬonsideration. That when the beam was on, it produced a steady stream of radiation. Historically, traditional fluoroscopy was typically continuous meaning Continuous Versus Pulsed FluoroscopyĪ very important issue to understand is the difference In fact, even when people think they are acquiring 30 frames per second, the truth is often something else altogether.
A range of factors come into play at every stage of the exam. In order to understand how technical considerations can influence the quality of data and information acquired during the videofluoroscopic swallowing assessment, it is important to understand the components involved in the generating, viewing, recording, and reviewing processes. Since 2007, questions regarding optimal image acquisition rate have been the focus of research conducted Professor Martin-Harris, Professor Bonilha, Professor Martino, and Professor Steele. In a videofluoroscopy exam, the aim is to capture the highest image quality possible while being responsible about limiting unnecessary radiation exposure, however there are many factors that can influence this.
