ARGDYP: an Adaptive Region Growing and DYnamic Programming Algorithm for Stenosis Detection in MRI
Jing Jiang, Ming Dong, Ewart Mark Haacke · 2006
In this paper, a novel image analysis algorithm adaptive region growing and dynamic programming (ARGDYP) is proposed for stenosis detection in magnetic resonance (MR) images. ARGDYP combines an adaptive region growing method for 3D vessel tracking and a dynamic programming approach for 2D vessel boundary detection. Our experiments based on both real and simulated MR data show that the proposed algorithm is able to accurately measure the cross sectional area of a blood vessel and thus determine whether or not there is a stenosis.
