Abstract
X-ray detector apparatus is provided for use in a CT imaging system having a rotatable gantry. The apparatus comprises a selected number of X-ray detector cells and two curved rails, which hold the detector cells in an array comprising an arcuate configuration and mount them onto the gantry for rotation therewith. Conduit segments are distributed along the rails, each conduit segment being proximate to a corresponding group of X-ray detector cells, and a quantity of selected working fluid and a porous wick structure is sealably enclosed in each conduit segment. The fluid is disposed to move along a conduit segment in gaseous form by means of convection, and to move in the opposing direction through the wick structure, in liquid form, by means of capillary action Heat is thereby transferred along a conduit segment to maintain a substantially isothermal condition among the detector cells proximate thereto.
