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.

[ What is claimed is:] [1.]1. Apparatus for detecting X-rays projected by an X-ray source comprising:a selected number of X-ray detector cells;a frame disposed to join said detector cells together to form an X-ray detector array, and to orient said detector cells to collectively receive said project

[ What is claimed is:] [1.]1. Apparatus for detecting X-rays projected by an X-ray source comprising:a selected number of X-ray detector cells;a frame disposed to join said detector cells together to form an X-ray detector array, and to orient said detector cells to collectively receive said projected X-rays;a selected number of conduit segments, each of said conduit segments being joined to said detector array proximate to a corresponding group of said X-ray detector cells;a quantity of selected working fluid sealably contained in each of said conduit segments; andmeans positioned within a given one of said conduit segments for enabling bidirectional flow of the fluid contained therein, in order to transfer heat along said given conduit segment from a first location to a second location, and to thereby maintain a substantially isothermal condition among respective detector cells of the detector cell group which is proximate to said given conduit segment.
