RADIATION DETECTOR AND COMPUTED TOMOGRAPHY APPARATUS USING THE SAME

摘要

The radiation detector includes image pixels that each includes a counting pixel, to restore an image. The counting pixel includes a radiation absorption layer, which converts incident photons into an electrical signal, and a photon processor that counts a number of the photons, based on the electrical signal.

主权项

1. A radiation detector comprising:
a plurality of image pixels each including at least one counting pixel which comprises:
a radiation absorption layer that converts incident photons into an electrical signal; anda photon processor that counts a number of the photons, based on the electrical signal transferred from the radiation absorption layer, wherein a number of the plurality of image pixels is smaller than a number of counting pixels.
