1. An energy-resolving photon counting detector pixel, comprising:
a photoconductor;
a charge sensitive amplifier, ‘CSA’, for integrating a photocurrent from the photoconductor and for outputting a CSA output signal relative to a CSA base level; and
a CSA base level shift detector for determining a shift in the CSA base level over time relative to a first level;
wherein the pixel is configured to reset the CSA in dependence of the determined CSA base level shift.
