Title: Hichem Maaref: Inventor in Medical Image Segmentation
Introduction
Hichem Maaref is an inventor associated with Évry-Courcouronnes, France. His work includes a patented method for identifying a thrombus and a related lesion in three-dimensional brain images.
Latest Patents
Maaref is associated with 1 patent, titled “Automatic Method for Segmentation of a Thrombus and a Lesion in a Three-Dimensional Brain Image.” The method uses supervised training of two recurrent artificial neural networks: one predicts lesions, and the other predicts thrombi. Their predictions are applied to image sets derived from a three-dimensional brain image and combined into segmentations. When multiple lesion segmentations are produced, the method selects the widest one as the lesion segmentation.
