1. A method, comprising:
- assigning points of interest (POIs) on blood vessels within an image dataset of a subject generated by a medical imaging system based on defined characteristics that may be associated with an aneurysm;
calculating one or more features of each POI; and
identifying, from among the assigned POIs, one or more aneurysm suspects based on the calculated features.

Abstract
A computer-aided system identifies aneurysm suspects in 3D image datasets. The system takes the raw image dataset as input and assigns one or more points of interest (POIs) in the image data. The system determines one or more features for each POI and identifies one or more aneurysm suspects from among the assigned POIs based on the determined features.

14. A method, comprising:
-
assigning points of interest (POIs) on blood vessels within an image dataset of a subject based on defined characteristics that may be associated with an aneurysm; for each assigned POI, calculating one or more features that may be indicative of the presence of an aneurysm; generating a list of aneurysm suspects from among the assigned POIs based on whether the one or more features for each assigned POI satisfy one or more threshold values; assigning a probability score to each aneurysm suspect; ranking the aneurysm suspects based on the probability score assigned to each aneurysm suspect; and displaying the list of aneurysm suspects and the probability score assigned to each aneurysm suspect. - View Dependent Claims (15, 16)
