Robust deformable image registration using cycle-consistent implicit representations

1 code implementation3 Oct 2023 Louis D. van Harten, Jaap Stoker, Ivana Išgum

To improve robustness, we propose a deformable registration method using pairs of cycle-consistent Implicit Neural Representations: each implicit representation is linked to a second implicit representation that estimates the opposite transformation, causing each network to act as a regularizer for its paired opposite.

Exploiting Clinically Available Delineations for CNN-based Segmentation in Radiotherapy Treatment Planning

no code implementations12 Nov 2019 Louis D. van Harten, Jelmer M. Wolterink, Joost J. C. Verhoeff, Ivana Išgum

We empirically assess how many clinical delineations would be sufficient to train a CNN for the segmentation of OARs and find that increasing the training set size beyond a limited number of images leads to sharply diminishing returns.

Automatic Online Quality Control of Synthetic CTs

no code implementations12 Nov 2019 Louis D. van Harten, Jelmer M. Wolterink, Joost J. C. Verhoeff, Ivana Išgum

We show that this uncertainty measure can be used for two kinds of online quality control.
