Class Activation Map-based Weakly supervised Hemorrhage Segmentation using Resnet-LSTM in Non-Contrast Computed Tomography images

no code implementations28 Sep 2023 Shreyas H Ramananda, Vaanathi Sundaresan

In this work, we propose a novel weakly supervised DL method for ICH segmentation on NCCT scans, using image-level binary classification labels, which are less time-consuming and labor-efficient when compared to the manual labeling of individual ICH lesions.

Brain tumour segmentation using a triplanar ensemble of U-Nets

1 code implementation24 May 2021 Vaanathi Sundaresan, Ludovica Griffanti, Mark Jenkinson

Our method achieved an evaluation score that was the equal 5th highest value (with our method ranking in 10th place) in the BraTS'20 challenge, with mean Dice values of 0. 81, 0. 89 and 0. 84 on ET, WT and TC regions respectively on the BraTS'20 unseen test dataset.
