These high energy photons are also used for therapeutic purposes in radiation therapy, where malignant tissue is destroyed by a focused deployment of high dose in the tumor. The treatment beam of this linear accelerator (LINAC) can also be used for imaging by means of so called electronic portal imaging devices (EPIDs). As we can see, medical imaging devices use a large part of the electromagnetic spectrum; since the mechanisms of tissue interaction with electromagnetic radiation are different, these machines deliver different information which may be used for diagnostic and therapeutic purposes.

The surface of the selenium layer is charged before the exposure. Then x-rays release charge carriers in the layer which dissipate the surface charge and leave an image of the remaining charge pattern. Capacitors assigned to each pixel store the charge which is then read out by means of a thin film transistor (TFT) matrix. Therefore, the resolution of the image only depends on the assembly of the detector. The amount of stored charge per pixel is directly proportional to the incident radiation.
