Final answer:
In fluoroscopy, the 'detector contrast' is determined by the characteristics and settings of the fluoroscopy equipment, which affects image contrast quality.
Step-by-step explanation:
The component of image contrast in fluoroscopy which is determined by the characteristics of fluoroscopy equipment and the effects of different equipment settings is referred to as detector contrast. Detector contrast involves the sensitivity of the device used (such as a fluorescent screen or camera) to electromagnetic radiation and how it records the observations. This contrast is essential because many microscopic objects do not absorb much light, resulting in low natural contrast. Various techniques, such as using stains or employing wave interference methods, are used to enhance contrast in microscopy. However, in fluoroscopy, the settings on the equipment can be adjusted to alter the intensity and quality of the images produced by affecting the detector contrast.
