Title
(EN) RENDERING OF B-MODE IMAGES BASED ON TISSUE DIFFERENTIATION
(FR) RENDU D'IMAGES EN MODE B SUR LA BASE D'UNE DIFFÉRENCIATION TISSULAIRE
Abstract
(EN) In some examples, tissue types in B-mode images may be differentiated by multiparameter imaging and/or other segmentation techniques. The tissue types may be used to assign material properties to voxels of the B-mode image, such as color, translucency, and reflectivity. The material properties may be used to generate a rendered image. In some examples, one or more of the material properties assigned to the voxels may correspond to values of tissue parameters acquired during multiparameter imaging. The rendered image may include data based on both the B-mode image and the multiparameter imaging.
(FR) Dans certains exemples, des types de tissu dans des images en mode B peuvent être différenciés par imagerie multiparamétrique et/ou d'autres techniques de segmentation. Les types de tissu peuvent être utilisés pour attribuer des propriétés matérielles à des voxels de l'image en mode B, telles que couleur, translucidité et réflectivité. Les propriétés matérielles peuvent être utilisées pour générer une image rendue. Dans certains exemples, une ou plusieurs des propriétés matérielles attribuées aux voxels peuvent correspondre à des valeurs de paramètres de tissu acquis pendant l'imagerie multiparamétrique. L'image rendue peut comprendre des données basées sur l'image en mode B et sur l'imagerie multiparamétrique.
