A detector (16) maintains thermal stability between two different operating modes. The detector (16) includes at least one controller (36, 38) which sets the detection sensitivity of the detector (16) to a level disabling the detection of gamma photons. The controller (36, 38) further controls a heat generator (36, 38, 86) to maintain the temperature of the detector (16) at a predetermined temperature. The predetermined temperature is the steady state temperature of the detector (16) when the detection sensitivity of the detector (16) is set to a level enabling the detection of gamma photons. A method (100) for maintaining thermal stability of a detector (16) between two different operating modes is also provided. |
