| This thesis is concerned with the improvement of image quality and the reduction of image quality degradation, primarily in digital X-ray angiography. The subsequent chapters describe techniques for the reduction of patient motion artifacts in digital subtraction angiography (DSA) images, noise reduction techniques for improved visualization and quantification of vascular anomalies in three-dimensional rotational angiography (3DRA) images, and interpolation techniques for the purpose of accurate geometrical transformation of medical image data in general. The results and conclusions of the evaluations described in this thesis provide general guidelines for the applicability and practical use of these techniques. |
