Reconstruction of vessels from MR-angiography data
|
|
Today pathologic changes in the blood vessel system belongs to the most
frequent causes physical disturbances (heart attack, stroke etc.). Therefore
it is very important for the medical diagnostic to registrate arteriosclerotic
vessel stenosis.
Imageproviding techniques for the representation of blood vessels are in
general summerized under the generic term Angiography.
The purpose of this project was to research the possibilities of knowledge-
and modell-based methods in digital image processing and pattern recognition
for MR-angiography and to create a larger MR-angiographical evaluating
program. After a prototype had been finished the system was tested in a
clinical environment. Hereafter, the positive results led to an integration
into the post-processing tool of SCR
(Siemens Corporate Research, Princeton, New Jersey) under Windows NT.
