Which part of the detector element (DEL) is responsible for detecting radiation?

The capture area of the detector element (DEL) is primarily responsible for detecting radiation. This area is designed to actively absorb the incoming X-rays or other forms of radiation. When radiation interacts with the capture area, it generates a signal that correlates to the energy and intensity of the incident radiation. This signal is then used to form an image based on the varying levels of radiation absorption across the detector.

The other parts of the DEL, such as the storage area, readout area, and output area, play supportive roles. The storage area is involved in retaining the detected signal temporarily, the readout area facilitates the conversion of stored signals into a usable form for processing, and the output area refers to the part where the processed information is sent for display or storage. However, it is the capture area that directly interacts with the radiation, making it the crucial component for detection.

Understanding the function of each section within the DEL helps clarify the workflow of digital radiography and emphasizes the importance of the capture area in generating high-quality diagnostic images.
