Abstract
A back-projector for use in a CT or other imaging system. For each pixel in the image that is to be reconstructed, a plurality of views of a scanned object are used to generate values for the pixel. The values from the multiple views are combined to yield a pixel value in the reconstructed image. The invention improves the speed and efficiency of existing systems by optimizing memory design and data path size within the back-projector and by implementing a perfect rounding system.
