Being the manner which decides the calcification level of the coronary artery

摘要

(57) Abstract Solutions Main invention of one feature is the method of forming the calcification level value with the CT graphics data making use of level attaching algorithm. According to one execution form of the aforementioned algorithm, the level attaching possible territory of the graphics data is identified, in the level attaching possible territory one attention territory is limited at least and calcium value is decided by calculating density value. After deciding the calcium value of each attention territory, total of calcium value is requested. Furthermore, total of the calcium value which is stressed for adjusting the non even interval and the discontinuous interval which are during graphics data slicing is requested.
