Question: 1 / 615

What is the efficiency range of solid-state detectors?

70-80%

80-90%

90-100%

Solid-state detectors are known for their high efficiency in converting incident radiation into detectable signals. The efficiency of these detectors typically lies within the range of 90-100%. This high efficiency is due to their ability to directly convert photon energy into electron-hole pairs through semiconductor materials, leading to a greater likelihood of detection compared to other types of detectors.

This characteristic makes solid-state detectors particularly advantageous in applications such as computed tomography (CT) and other diagnostic imaging techniques, where optimal detection of X-rays and other forms of radiation is crucial for image quality and patient safety. Their high efficiency enables lower doses of radiation to be used while still achieving clear images, which is a significant benefit in medical imaging.
