Abstract
The present invention relates to a photon counting detector comprising a first direct conversion layer () comprising a low-absorption direct conversion material () for converting impinging high-energy electromagnetic radiation () into a first count signal and first electrical contacts (), a second direct conversion layer () comprising a high-absorption direct conversion material () for converting impinging high-energy electromagnetic radiation () into a second count signal and second electrical contacts (), said high-absorption direct conversion material having a higher absorption than said low-absorption direct conversion material, and a carrier layer () comprising first and second terminals () in contact with the first and second electrical contacts and processing circuitry () configured to correct, based on the first count signal, the second count signal for errors, wherein said first direct conversion layer and the second direct conversion layer are arranged such that the high-energy electromagnetic radiation transmits the first direct conversion layer before it hits the second direct conversion layer.
