Algorithms for segmenting cerebral time-of-flight magnetic resonance angiograms from volunteers and anemic patients.
Abstract
Purpose: To evaluate six cerebral arterial segmentation algorithms in a set of patients with a wide range of hemodynamic characteristics to determine real-world performance.
Approach: Time-of-flight magnetic resonance angiograms were acquired from 33 subjects: normal controls (N = 11), sickle cell disease (N = 11), and non-sickle anemia (N = 11) using a 3 Tesla Philips Achieva scanner. Six segmentation algorithms were tested: (1) Otsu’s...
