Abstract: 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.

Abstract: A detector imaging system having an apparatus and method for correcting defective pixels in an acquired image is disclosed herein. The system includes a correction scheme including temporarily replacing a defective pixel with a linear interpolation of the defective pixel's surrounding neighboring pixel values, determining a local gradient based in part on the acquired image and a gradient kernel, and providing a correction value based on the local gradient to correct the defective pixel. The correction scheme is repeated a plurality of times as desired to correct all the defective pixels in the acquired image.
