Analysis of 2D Phase Contrast MRI in Renal Arteries by Self Organizing Maps
We present an approach based on self organizing maps to segment renal arteries from 2D PC Cine MR images to measure blood velocity and flow. Such information are important in gradi...

Automatic Correction of Intensity Nonuniformity from Sparseness of Gradient Distribution in Medical Images
We propose to use the sparseness property of the gradient probability distribution to estimate the intensity nonuniformity in medical images, resulting in two novel automatic metho...
