Technical studies of angiotomography for good demonstration of the vessels in the basal ganglia were described using a Princeps 50 unit. From analyses of image quality and blurring effect of interfering shadows in multilayer tomography, the following technical factors were obtained for good demonstration of the vessels : five simultaneous cuts at 2mm interval and swing angle of 30〜40 degrees in lateral projection, and five simultaneous cuts at 5 or 10mm interval and swing angle of 10〜20 degrees in frontal projection. Combination with photographic subtraction was particularly useful for good visualization of intracerebral avascular area.
