Final answer:
A solid-state radiation detector is the device that can record up to twelve images per second during conventional fluoroscopy. These detectors have replaced traditional X-ray film or image intensifiers due to their faster image acquisition capabilities.
Step-by-step explanation:
The device that can record up to twelve images per second during conventional fluoroscopy is a solid-state radiation detector. Solid-state radiation detectors are used in various medical imaging techniques, including conventional fluoroscopy, to capture images of the internal structures of the body.
Fluoroscopy is a technique in which continuous X-ray images are captured to visualize the movement of internal organs or structures in real-time. Traditional X-ray film or image intensifiers were used in the past, but solid-state detectors have replaced them due to their ability to provide faster image acquisition.
These detectors can capture multiple images per second, with some models capable of recording up to twelve images per second. This high frame rate allows for more detailed examination of dynamic processes, such as the movement of organs, blood vessels, or contrast agents within the body.
