Non invasive quantitative myocardium flow appraisal

摘要

The heart computer legible medium in order to appraise flow quantitatively, the device and method. The myocardium which is displayed in the consecutive heart picture is divided by the picture segment, the picture segment has the picture pixel of 1 at least. The heart flow parameter, is decided concerning each of the aforementioned picture segment. The picture segment of 1 where it possesses proper flow parameter value is selected, at least. After that, the heart of the remaining picture segment flow parameter the normality is done to that is based on aforementioned proper flow parameter value of aforementioned picture segment which possesses flow. According to one execution example, as for flow parameter, it is largest up-grade of the time - strength profile regarding the distribution of the contrast medicine in the aforementioned myocardium. Proper largest up-grade, is deduced at least concerning the picture segment of 1, relative largest up-grade, is calculated concerning the respective segment, vis-a-vis proper largest up-grade. On the basis of these values, when loading the myocardium which is deduced ratio of flow parameter and the myocardium which is deduced at the time of repose flow parameter, can be calculated concerning the respective segment. For example the myocardium flow extra talent exponent (MPRI), is calculated as a time of repose and when loading a ratio of the relative largest up-grade which is deduced, concerning the respective picture segment.
