What fluoroscopic technique allows a practitioner to obtain a permanent image during a live fluoroscopy sequence?

Frame grabbing is the technique that allows a practitioner to capture a single frame from a live fluoroscopy sequence, resulting in a permanent image. This is particularly useful in clinical situations where specific anatomical details or events need to be documented for further analysis or record-keeping.

In the context of fluoroscopy, real-time imaging refers to continuous visualization of the moving anatomy, which allows practitioners to observe physiological processes as they happen but does not create a permanent record. Static imaging, on the other hand, involves taking a still image, but it is distinct from frame grabbing, as it may not involve the actual live sequence from fluoroscopy. Image acquisition encompasses various methods of capturing images but is a broader term that does not specifically refer to the technique of capturing a single frame from dynamic data.

Thus, frame grabbing is the correct answer since it specifically describes the ability to capture those critical images during real-time procedures for documentation and subsequent review.
