摘要： Systems, methods and apparatus are provided through which a collimator has one or more varying physical characteristics that have the effect of varying the absorption of electromagnetic energy from a low extent of absorption at a leading edge to the same extent of absorption as the remainder of the collimator. In some embodiments, the collimator has a tapered knife-edge. The varying absorption of electromagnetic energy at different points along the collimator reduce abrupt transitions of projection of the electromagnetic energy onto an electromagnetic energy detector, thereby reducing erroneous artifacts in an image generated by the detector.

摘要： Systems and methods are provided for offset correction of images from a flat panel detector. In some embodiments, the apparatus and method develops one or more offset maps, acquired during system idle, for the imaging system at a plurality of exposure windows. In some embodiments, exposure parameters acquired for the imaging system before image acquisition are used to select an offset map to subtract from subsequent X-ray images. In some further embodiments, executable instructions are disclosed for directing a processor to compile one or more offset map and exposure parameters to subtract based on a selected offset map noise elements from X-ray images and thereby minimizing the time between image acquisition and display of processed images.

摘要： A technique for selectively processing data from a digital detector includes determining an image area produced by orientation of a radiation source assembly. The assembly may include a radiation source and a collimator, which may be separately orientable. The image area is computed based upon the orientation of the radiation source assembly that projects a radiation beam towards an imaging plane. Image data from a detector within the imaging plane is selectively processed to improve computational efficiency. The system may also determine whether the image area falls within the imaging surface of the detector and inform an operator or inhibit an exposure if such is not the case.
