Statistical inference of the inter-sample Dice distribution for discriminative CNN brain lesion segmentation models

no code implementations4 Dec 2020 Kevin Raina

For a trained discriminative CNN to be used in clinical practice, the patient's radiological features are inputted into the model, in which case a conditional distribution of segmentations is produced.

Modelling brain lesion volume in patches with CNN-based Poisson Regression

no code implementations26 Nov 2020 Kevin Raina

The ISLES2015 (SISS) data is used to train and evaluate the model, which by estimating lesion volume from raw features, accurately identified the lesion image with the larger lesion volume for 86% of paired sample patches.

Exploiting bilateral symmetry in brain lesion segmentation

no code implementations18 Jul 2019 Kevin Raina, Uladzimir Yahorau, Tanya Schmah

Specifically, we use nonlinear registration of a neuroimage to a reflected version of itself ("reflective registration") to determine for each voxel its homologous (corresponding) voxel in the other hemisphere.
