Abstract

The Dynamic Spatial Reconstructor (DSR) is a 14 x-ray source, video imaging system which operates on the computerized tomography scanning principle. It scans a cylindrical volume, 18.5 cm in axial height, with equal resolution in the transverse and axial directions and repeats this 'volume scan' (of up to 240 0.7 mm thick, parallel slices) at 16.67 ms intervals. The output of each of the 14 video imaging systems is A/D converted, shading corrected and stored in 64 megabytes of memory. The memory is used efficiently because the shading correction reduces the gray scale information of the pixels from 12 to 10 bits and because we need record only a selectable region of interest within the full video image.
