(EPSRC DTP) Image translation using multichannel generative adversarial networks for automatic tumour delineation

Project Description

Inter-observer error in tumour delineation is a significant source of uncertainty in the cancer patient pathway. Presently, the individual practice of the observing clinician dictates the treatment plan. While mandatory peer review helps to reduce this variation, it is time consuming and unstandardised. The variable nature of tumour location and physical anatomy means consistency becomes very difficult to achieve when performing delineations by hand. This project seeks to explore the application of various machine learning techniques to automate tumour volume delineation for radiotherapy of glioblastoma, aiming to shift the paradigm of radiotherapy treatment planning towards unbiased computational methods driven by Multi-Channel Generative Adversarial Networks (MCGADs) [1].

The ideal network should consist of a generator which will be trained to take a CT and/or PET image [2] of a brain with a Glioblastoma Multiforme (GBM) type tumour and manipulate the image such that it removes the tumour from the scan. The model will learn through the use of tumour free brain scan images. Through the analysis of areas with statistically significant variation during translation, a tumour can be identified. Simultaneously, a discriminator should be trained to differentiate between synthesised and real data. Ideally, the dynamic model could also be trained in reverse to allow the manipulation of images in order to create a tumour in the image from a healthy scan to be used as a training tool. While the model will clearly have clinical relevance, its applications will not be confined to oncology. The architecture should be able to modify data such that the high-level features are preserved; this form of image synthesis is applicable to any form of image and potentially adaptable to any form of input.
