X-ray detectors are devices used to capture and convert X-ray radiation into images or data. They play a crucial role in medical imaging, allowing healthcare professionals to visualize the internal structures of the body. Common types of X-ray detectors include flat-panel detectors and computed radiography systems, each with unique features and applications. These detectors work by absorbing X-rays and producing electrical signals that are then processed to create images. The quality and speed of the imaging process can vary depending on the type of detector used, impacting diagnosis and treatment planning in fields like radiology and dentistry.
