Algorithm for Automatic Placement of ROI’S and Calculation of Contrast Recovery and Background Variability in Nema-IQ Phantom

Abstract: The present work deals with A new approach for the automation tool for the analysis and evaluation of images as per the requirements of NEMA standards so that change in orientation of spheres in the phantom can be well taken care of. This tool supports automatic segmentation of lesions in the phantom images, calculation of Background Variability & Contrast Recovery for various orientations of spheres.

Keywords: Automation tool, NEMA standards, automatic segmentation of lesions in the phantom images.
