ABSTRACT:
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.
