Abstract: A digital radiographic detector uses predetermined calibration information corresponding to a first operating temperature of the detector. The calibration data is accessible by the detector to compensate a radiographic image captured by the detector at a second operating temperature different than the first operating temperature. The operating temperature of the detector is monitored at approximately the time at which the radiographic image is captured at the second temperature.

Abstract: An existing radiation treatment plan is accessed for a given patient as well as first information (such as automatically generated updated information) regarding at least one physical characteristic as corresponds to the radiation treatment of this patient. One then initiates, prior to receiving second information (such as user input) regarding the first information, an automatic adaptation process to adapt the treatment plan to accommodate the first information. Upon later receiving second information regarding the first information, one then modifies the automatic adaptation process itself to incorporate the second information regarding the first information.

Abstract: A computed tomography scanner has multiple radiation sources or source arrays, in specific geometric dimensions for optimized imaging speed. A CT system with maximum fan-angle ? and K simultaneously active x-ray sources distributed over an angle of ??2? radians, the sources partially overlapping on a detector array, measures summed projection data corresponding to K or less line-integrals at each detector element. When the CT machine's dimensions RM, Rd, and RS, corresponding respectively to the measurement field-of-view, detector distance from iso-center, and source distance from iso-center, are such that projections of the two extreme radiation sources do not overlap on the detector, the individual line-integrals can be recovered by inversion of linear systems comprising K or less rows in fewer unknown than rows; the unknowns given by the exponential of the negative of the line integrals to be recovered. The CT scanner then reconstructs an image from the line-integral estimates.
