Abstract
The invention relates to a detection device () for detecting photons emitted by a radiation source (). A signal generation unit () generates a detection signal indicative of the energy of a detected photon while photons strike the detection device (), and a baseline signal, which is affected by photons that previously struck the detection device (), while photons are prevented from striking the detection device (). A baseline shift determination unit () determines a baseline shift of the detection signal depending on the baseline signal. An energy determination unit () determines the energy of a detected photon depending on the detection signal and the determined baseline shift. Since the baseline shift of the detection signal is determined from a baseline signal that is generated while photons are prevented from striking the detection device (), the baseline shift can be determined with higher accuracy, resulting in an improved energy determination.
