Abstract:
Disclosed are a method and an apparatus for determining blood flow requirement, a method and an apparatus for producing a blood flow image, a method and an apparatus for processing a myocardial perfusion image. The method for determining blood flow requirement include a step of distinguishing the morphological information of coronary artery on a heart region; a step of dividing the heart image into at least one myocardium by using the distinguished morphological information of coronary artery; and a step of determining blood flow requirement according to the divided myocardium. [Reference numerals] (110) Apparatus for determining blood flow requirement; (120) Coronary identification unit; (130) Myocardial area division unit; (140) Unit for determining the blood flow requirement
Abstract:
Disclosed is a method of performing the segmentation of vessel using thresholds. One embodiment includes obtaining an image including slices (slice includes the cross section of the vessel) by using a contrast medium, setting adaptively the thresholds corresponding to each cross section based on modeling information related to the intensity of the contrast medium, and performing the segmentation of vessel based on the image and the thresholds. Here, the thresholds corresponding to each cross section can determine the boundary of each cross section.
