a method of image processing is provided for generating an image of an object in a computer x - ray tomography apparatus having an x - ray source and a detector . the method desirably permits relatively coarse spacing between adjacent detector views and correspondingly lowers exposure to x - ray radiation while maintaining a high resolution image . the method includes the step of acquiring actual detector data for multiple views of the object . after actual detector data is acquired for adjacent views of the object , the actual detector data from these adjacent views is interpolated to obtain virtual detector data between the adjacent views as though a virtual detector had been placed therebetween . the actual detector data and the resultant virtual detector data is then mapped into radon space . the process is repeated until radon space is sufficiently filled with actual detector data and virtual detector data to permit image reconstruction . a radon inversion is then performed on the filled radon space to reconstruct the image .
