Abstract: A method is described for the combined processing of spectral data from a plurality of radiation detectors (4,6), in particular with a plurality of response functions, comprising: obtaining a response matrix for each detector (4,6); collecting data from radiation incident at each detector (4,6); producing a spectral histogram for the collected data from each detector (4,6); deconvoluting the histograms from each detector by applying a suitable numerical deconvolution such as a Bayesian deconvolution that makes use of the response matrix for each detector to derive a single spectral histogram that representatively combines information from the plurality of detectors. An apparatus, such as a hybrid detector apparatus, to which the method can be applied is also described.

Abstract: Means for enhancing heat transfer from liquid cooled rotating anode x-ray tubes that provide for extended surfaces on the liquid cooled concave curved heat exchange surfaces opposing the electron beam focal track. The extended surfaces take the form of fins lying in the direction of coolant flow, said fins preferably being generally triangular in cross section.

Abstract: The present invention provides an internally liquid cooled rotating target of high average power capabilities that is illuminated by an energy beam wherein multiple independent centrifugal forces are established on an associated heat transfer surface to enhance heat transfer.

Abstract: A method for providing an approximately uniform temperature distribution on a cold plate that has at least one of a non-uniform temperature distribution on its heated surface and non-uniform wall thickness separating the heated surface from the generally opposing fluid cooled surface. Low thermal conductivity material is selectively deposited on the fluid cooled surface of the cold plate such that the resulting local thermal resistivity combined with the corresponding local heat flux results in an approximately constant temperature over the heated surface on the cold plate.

Abstract: Rotating anode x-ray generating apparatus including a mechanism which utilizes the rotational motion of the anode (20) to increase the effective rate of coolant with respect to the anode heat exchange surface (43).
