A DYNAMIC REAL TIME DSA SYSTEM AND A NEW METHOD OF MEASURING HEART FUNCTIONS

This paper briefly describes a dynamic real time digital subtract angiography system. The system can perform real time digital subtract angiography with a general personal computer and a specially designed DSA image memory processor. Thesystem hardware, mass storage live image memory processor and the functions of DSA software system are described. A new method of measuring heart functions by using DSA image is also described.
