摘要: A detector maintains thermal stability between two different operating modes. The includes at least one controller which sets the detection sensitivity of to a level disabling gamma photons. further controls heat generator maintain temperature predetermined temperature. is steady state when set enabling method for maintaining modes also provided. Approaches are disclosed normalize acquired imaging data during image reconstruction using dark current-dependent normalization factors.
