Tomography detector temperature equalization |
摘要 |
Temperature control of solid state detectors carried on the rotating gantry of computed tomography equipment is impractical for very detailed images. The temperatures of all of the detectors in the array can be equalized, however, by closely coupling them to a thermally massive object and isolating this combination from the environment. Significant thermal gradients are thereby removed from the array, and time is removed as a calibrating factor. The detectors are mounted on a common heat sink which provides the thermal mass, and the heat sink is covered with insulation and attached to the gantry by thermally isolating mounts, such as thin flexible stainless steel plates.
