Outline of Final Research Achievements

The way how to decompress unreadable 4D-DSA images stored in a medical workstation and output time-resolved 3D images were established. Furthermore, most of the work from the process of extracting intensity of contrast agent from an arbitrary location in the region of interest to the process of making that graph was automated. This automation is important to execute this protocol on many cases or develop the medical software. Moreover, a time-intensity curve, which shows the relationship between time and intensity of contrast agent, was made for the inlet boundary in computational fluid dynamics simulations and the heart rate and hear state were successfully adjusted by referring to that curve.
