Which of the following makes up a single detector element (DEL)?

A single detector element (DEL) in digital radiography comprises a capture area, a storage capacitor, and a thin film transistor (TFT) gate. The capture area is responsible for receiving the X-ray photons and converting them into electronic signals. The storage capacitor temporarily stores the electrical charge generated by the incident radiation. The thin film transistor serves as a switch that controls the readout of the stored signal, allowing for the conversion of the charge into a digital signal that can be processed and displayed as an image.

The structure of a DEL is crucial for the functioning of flat-panel detectors used in digital radiography, as it directly impacts the efficiency of image formation and quality. The integration of these components allows for effective detection of radiation and ensures that the resulting images have the necessary resolution and clarity for diagnostic purposes.

The other options presented do not accurately represent the components of a DEL; they instead refer to different systems or technologies that are not part of a single detector element in the context of digital radiography.
