The feature that reduces exposure to patients by recalling the last fluoroscopic image is known as what?

• A. Image storage
• B. Image recycling
• C. Last image hold
• D. Previous exposure recall

Answer: (C)

The term that refers to the feature that reduces exposure to patients by recalling the last fluoroscopic image is commonly known as "last image hold." This feature is essential in fluoroscopy as it allows the operator to display the last static image captured during a fluoroscopic examination without the need for continuous radiation exposure when the fluoroscope is not actively imaging. By utilizing this functionality, radiologists can review and assess the patient's condition without re-exposing them to potentially harmful ionizing radiation, thereby enhancing patient safety.

The other options do not accurately describe this specific feature. "Image storage" generally refers to the methods and technologies used to store images for later retrieval, while "image recycling" may imply reusing data in some way but does not directly address patient exposure. "Previous exposure recall" could suggest retrieving past exposure data but does not convey the immediate use of the last image to reduce radiation during fluoroscopic studies.
