Latest Patents

Yan Xu's latest patents include innovative frameworks aimed at improving medical image registration. One of his notable inventions is a method for preserving tumor volumes during unsupervised medical image registration. This framework addresses the challenge of disproportionate volume changes in tumor regions by employing a two-stage process. The first stage utilizes similarity-based registration to identify potential tumor regions, generating a soft tumor mask. The second stage implements a volume-preserving registration network that adapts the loss function based on the calculated masks, ensuring a balance between image similarity and volume preservation.

Another significant patent involves a weakly-supervised framework for 3D medical image segmentation. This framework incorporates geometric prior and contrastive similarity to enhance the distinguishability of organs amidst complex shapes and image artifacts. By utilizing bounding-box annotations for training, the framework builds a geometric prior based on point-cloud representations, which are more flexible than traditional volume representations. The use of contrastive similarity further aids in effectively distinguishing low-contrast tissues from the background.
