What is the Last Image Hold feature and its clinical use?

• A. Last Image Hold displays and allows review of the most recently captured frame during a procedure to aid decision-making with minimal additional dose.
• B. Last Image Hold erases previous images for privacy.
• C. Last Image Hold automatically adjusts exposure parameters.
• D. Last Image Hold increases radiation dose.

Answer: (C)

Last Image Hold stores and displays the most recently captured fluoroscopic image, letting you review that frame during a procedure without taking a new exposure. This helps with quick decision-making and comparison to prior views while keeping radiation exposure low because you’re not adding another dose just to review what you just captured. Clinically, it’s useful for checking device or catheter position, confirming alignment, or evaluating anatomy without repeated imaging. It’s not about automatically changing exposure parameters, erasing images, or increasing dose—those functions come from other controls.
