Abstract

Optimal localization is needed to remove the hazards generated in patient treatment through distortion correction, automatic detection method for fiduciary markers and target tumor. Automatic detection algorithms for DSA and CT were developed. Base on these algorithms, an error correction algorithm was proven to be adequate for stereotactic radiosurgery despite its having some errors. In the case of image fusion, with overall algorithms, DSA/CT/MRI could be integrated to provide better resolution as well as pathological information
