摘要：

A digital radiographic installation for medical diagnostic is described. Distribution of X-ray intensity in horizontal direction is measured by a one-coordinate MWPC with a 1.2 mm channel. A two-dimensional image is produced by mechanical scanning with 1 mm channel width in vertical direction. The number of pixels in the image is 320 x 256. The MWPC works in count mode with quantum efficiency 25% (50 keV) and count rate capability 600 kHz/channel. Results of testing a prototype with 64 channels 0.6 mm width are also presented.
