Computed tomography with detector wobble

A method for acquiring signals from a radiation detector, comprising:

• reading out a plurality of sub-pixels of a radiation detector in an alternating manner, in which:
• during a regular readout operation, separately acquiring a first analog signal from a first sub-pixel and a second analog signal from a second sub-pixel adjacent to the first sub-pixel in a first direction and summing the first analog signal and the second analog signal to generate a summed regular pixel digitized signal;
• and
• during a wobble readout operation, separately acquiring a fourth analog signal from the first sub-pixel and a third analog signal from a third sub-pixel adjacent to the first sub-pixel in a second direction and summing the fourth analog signal and the third analog signal to generate a summed wobble pixel digitized signal.

A radiation detector comprising:

• a plurality of pixels, each pixel divided into a first sub-pixel and a second sub-pixel;
• a readout path for each first sub-pixel and second sub-pixel, wherein each readout path is available for a first state in which outputs of the first sub-pixel and the second sub-pixel of the same respective pixels are combined and a second state in which outputs of the first sub-pixel and the second sub-pixel of different pixels are combined;
• a controller configured to assign the readout paths between the first state and the second state during operation;
• and
• an ASIC configured to allow integration of the readout signal so that the summed signal from different summing locations can be readout simultaneously.
