ABSTRACT:
A method of and apparatus for radiation detection including temperature control so that the temperature of the radiation detector, which includes a photodiode with a leakage current of 0.4-18 pA, is controlled to a setup temperature plus or minus 0.35.degree. C. With this condition established, offset data and reference data of the detector are collected in the absence of a body under test, offset data immediately before an actual signal measurement is collected and thereafter signal data through the exposure of a body under test is collected. The collected data are subjected to sensitivity calibration and offset calibration, thereby to obtain projection data, and image data is obtained through image processing of the projection data.
