RADIATION IMAGING DETECTOR WITH CHARGE TRANSFER READOUT

摘要

The invention provides a radiation imaging detector comprising: a) a first dielectric layer (1), b) a plurality of electric field shaping electrodes (2) deposited on the first dielectric layer (1), c) a charge accumulating electrode (3) deposited on the first dielectric layer (1), d) a second dielectric layer (4) deposited over the electric field shaping electrodes (2) and the charge accumulating electrode (3), e) readout electrodes (5) deposited over the second dielectric layer (4), f) a radiation charge conversion layer (6) deposited over the second dielectric layer (4) and the readout electrodes (5), and g) a top bias electrode (7). The invention further provides a method for detecting radiation comprising the steps of a) providing the radiation imaging detector described above, b) generating a read out image signal, and c) detecting said read out image signal.
