Given two connected subsets Y β X of the set of the surfels of a connected digital surface, we propose three equivalent ways to express Y being homotopic to X . The first characterization is based on sequential deletion of simple surfels. This characterization enables us to define thinning algorithm

In modern clinical practice, Digital Subtraction Angiography (DSA) is a powerful technique for the visualization of blood vessels in a sequence of X-ray images. A serious problem encountered in this technique is the presence of artifacts due to patient motion. The resulting artifacts frequently lead
## Abstract A bolus chase threeβdimensional (3D) MR digital subtraction angiography (MRDSA) technique was implemented using dynamic __k__βspace filling. This technique permits rapid 3D arterial imaging of the entire lower extremity at multiple stations using a single intravenous injection. Image ac
