In fluoroscopy, what does "frame rate" refer to?

In fluoroscopy, "frame rate" specifically refers to the number of images displayed per second. A higher frame rate allows for smoother motion visualization, which is crucial in real-time imaging procedures. This characteristic is vital for dynamic studies where the movement of organs, blood flow, or other physiological processes need to be observed clearly and accurately. By having a higher frame rate, it ensures that transitions between images happen seamlessly, enhancing the overall diagnostic effectiveness and viewer experience. The importance of frame rate is particularly evident in procedures like interventional studies, where monitoring the movement of instruments or contrast agents is critical for successful outcomes.
