1. An X-ray imaging system comprising an X-ray detector, the X-ray detector comprising
a detector panel comprising a surface with a plurality of detector pixels, wherein the detector pixels are configured to convert received X-rays into electric signals representative of values indicative of the received X-rays;
a data interface configured to transmit images having a fixed number of output pixels; and
a control unit configured to control to:
set a region of interest comprising at least a subset of the plurality of detector pixels, wherein a number of detector pixels in the region of interest is independent of the number of output pixels, wherein the output image has a number of output pixels in a first direction and a number of output pixels in a second direction and wherein any multiple of the number of output pixels in the first direction is different from the number of detector pixels in the first direction in the region of interest or any multiple of the number of output pixels in the second direction is different from the number of detector pixels in the region of interest in the second direction,
map the region of interest onto an output image having the fixed number of output pixels,
resample the detector pixels within the region of interest to obtain values for the output pixels of the output image, and
transmit the output image via the data interface.
