What is the function of the last image hold feature in fluoroscopy?

The last image hold feature in fluoroscopy is primarily designed to freeze the most recently captured image on the screen. This functionality is crucial in various clinical scenarios, allowing healthcare professionals to maintain a static image for further evaluation and analysis without the distractions that come with real-time motion. By freezing the image, the practitioner can assess important details, look for abnormalities, or discuss findings with colleagues before proceeding with further imaging or interventions.

The capability to freeze the last image enhances the diagnostic utility of fluoroscopy, especially when it involves complex procedures where detail is important. While options like saving the image for review or analyzing previous images could be beneficial in other contexts, they do not directly describe the instantaneous effect of freezing an image for immediate assessment. Displaying motion in real-time is another function of fluoroscopy but does not pertain to the last image hold feature, which specifically focuses on maintaining a single frame for meticulous inspection.
