What is one advantage of CCDs over a video tube camera system in mobile fluoroscopy?

The advantage of CCDs (Charge-Coupled Devices) over a video tube camera system in mobile fluoroscopy is the elimination of lag. In imaging systems, especially in fluoroscopy, lag refers to the delayed response of the detector to changes in the image scene. This is particularly crucial in dynamic imaging, where real-time visualization is necessary.

CCDs have a much faster response time compared to video tube cameras, leading to more immediate image production without lag. This allows for smoother and more continuous imaging, which is essential in procedures that require real-time feedback, such as interventional radiology. The absence of lag enhances the ability to capture high-quality images during fast-moving procedures.

Other options, such as increased size and weight, higher operating voltages, and lower sensitivity, do not represent advantages of CCDs. In fact, CCDs are generally more compact and lightweight, operate at lower voltages, and possess higher sensitivity to light, making them more efficient and effective for mobile fluoroscopy applications.
