We address the problem of motion artifact reduction in digital subtraction angiography (DSA) using image registration techniques. Most of registration algorithms proposed for application in DSA, have been designed for peripheral and cerebral angiography images in which we mainly deal with global rigid motions. These algorithms did not yield good results when applied to coronary angiography imag...

I MAGING OF the chambers of the heart, pulmonary circulation, and great vessels by intravenous (IV) contrast injection was clinically implemented as early as 1939.’ It was not until the achievement of relatively recent advances in digital electronics, image intensification, and television technology that a major resurgence of interest in this technique occurred. These technological advances in ...

Three-dimensional (3D) digital subtraction angiography (DSA) is the latest development in the neurovascular imaging armamentarium. 3D-DSA combines the anatomic resolution of DSA with 3D visualization abilities previously offered by only CT or MR angiography. 3D-DSA provides more detailed information than does DSA alone in the evaluation of neurovascular lesions, such as cerebral aneurysms. Howe...
