Low-rank based motion correction followed by automatic frame selection in DT-CMR

Autor: Wang, Fanwen, Ferreira, Pedro F., Munoz, Camila, Wen, Ke, Luo, Yaqing, Huang, Jiahao, Wu, Yinzhe, Pennell, Dudley J., Scott, Andrew D., Nielles-Vallespin, Sonia, Yang, Guang

Publikováno v: ISMRM 2024 Digital poster 2141

Motivation: Post-processing of in-vivo diffusion tensor CMR (DT-CMR) is challenging due to the low SNR and variation in contrast between frames which makes image registration difficult, and the need to manually reject frames corrupted by motion. Goal

Stain Consistency Learning: Handling Stain Variation for Automatic Digital Pathology Segmentation

Autor: Yeung, Michael, Watts, Todd, Tan, Sean YW, Ferreira, Pedro F., Scott, Andrew D., Nielles-Vallespin, Sonia, Yang, Guang

Stain variation is a unique challenge associated with automated analysis of digital pathology. Numerous methods have been developed to improve the robustness of machine learning methods to stain variation, but comparative studies have demonstrated li

Style Transfer and Self-Supervised Learning Powered Myocardium Infarction Super-Resolution Segmentation

Autor: Wang, Lichao, Huang, Jiahao, Xing, Xiaodan, Wu, Yinzhe, Rajakulasingam, Ramyah, Scott, Andrew D., Ferreira, Pedro F, De Silva, Ranil, Nielles-Vallespin, Sonia, Yang, Guang

This study proposes a pipeline that incorporates a novel style transfer model and a simultaneous super-resolution and segmentation model. The proposed pipeline aims to enhance diffusion tensor imaging (DTI) images by translating them into the late ga

Efficient Post-processing of Diffusion Tensor Cardiac Magnetic Imaging Using Texture-conserving Deformable Registration

Autor: Wang, Fanwen, Ferreira, Pedro F., Wu, Yinzhe, Munoz, Camila, Wen, Ke, Luo, Yaqing, Huang, Jiahao, Pennell, Dudley J., Scott, Andrew D., Nielles-Vallespin, Sonia, Yang, Guang

Diffusion tensor cardiac magnetic resonance (DT-CMR) is a method capable of providing non-invasive measurements of myocardial microstructure. Image registration is essential to correct image shifts due to intra and inter breath-hold motion and imperf

Random walk diffusion simulations in semi-permeable layered media with varying diffusivity

Autor: Alemany, Ignasi, Rose, Jan N., Garnier-Brun, Jérôme, Scott, Andrew D., Doorly, Denis J.

In this paper we present analytical and random walk based solutions to diffusion in semi-permeable layered media with varying diffusivity. We propose a new random walk transit model (hybrid model) based on treating the membrane permeability and the c
