X-RAY IMAGE ACQUISITION APPARATUS

摘要

An X-ray image acquisition apparatus (15) includes a conversion panel (20) aligned with a photo detector array (40). The conversion panel (20) includes a plurality of conversion cells, each including a conversion body, an X-ray transparent and light reflective file over the top of the body, and a light reflective film surrounding the body. The body is made of a scintillating material that efficiently generates optical light photons in response to X-ray radiation illuminating thereon and is substantially transparent to the optical light photons. The body is also sufficiently long to absorb the X-ray radiation over a wide range of energy levels. The light reflective films collimate the optical light photons generated in the body toward the photo detector array (40) to form X-ray images.
