METHOD AND SYSTEM FOR MAGNETIC RESONANCE (MR) IMAGE ANALYSIS

This abstract first appeared for US patent application 20250006346 titled 'METHOD AND SYSTEM FOR MAGNETIC RESONANCE (MR) IMAGE ANALYSIS

Original Abstract Submitted

existing magnetic resonance (mr) analysis approaches are either manual, which is time consuming and error prone, or automatic yet fail to identify correct landmarks. the disclosure herein generally relates method and system for mr image analysis. the system trains and uses a generative adversarial network (gan) for the mr image analysis. a generator network of the gan generates a heatmap of a plurality of landmarks, by processing input data. further, a discriminator network of the gan, which has gradients updated based on a modified discriminator loss (mdl) calculated based on a foreground pixel loss function and a standard discriminator loss, predicts each of a plurality of patches in a second input data as one of real and fake, based on presence of the one or more foreground pixel regions in the landmark heatmap in the ground-truth heatmap identified based on the foreground pixel loss function.
