ARGDYP: An Adaptive Region Growing and Dynamic Programming Algorithm for Stenosis Detection in MRI

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 3-D vessel tracking and a dynamic programming approach for 2-D 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.
