概要

This report describes a new stereoscopic DSA system using a twin focus X-ray tube which can reconstruct a series of stereoscopic subtraction images by a single injection of contrast medium. Main points which we refer to in this paper are as follows. 1. A real-time stereoscopic view of moving images has been realized on a single TV monitor by this system. 2. A new automatic diaphragm designed for this system and some compensatory filters attached to the image intensifier provide good images without halation. 3. The digital image memories in this system are sufficient enough for large high-speed data acquisition. They are equal to the same series of images taken during conventional stereoscopic serial angiography. 4. The interfocal distance of 63 mm in the X-ray tube provides a stereoscopic pair which can be seen without a sense of incompatibility within a 1.25-fold-magnification through a 10 inch image intensifier. 5. The stereoscopic DSA is greatly appreciated for clinical application.
