Dear all,
Next week, we have the pleasure of having Prof. Leo Joskowicz give a talk in the colloquium.
The seminar will be held on Monday, February 5th, at 14:00. Location: C220.
The title, abstract and bio appear below.
Looking forward to seeing you, Sagie and Liat
*Title:* Three is better than two and better than one: simultaneous deep learning for lesion changes analysis in medical images.
*Abstract:* Monitoring cancer patients undergoing treatment requires the analysis by an expert clinician of radiological images acquired every few months. With improvements in treatments leading to longer patient lifespans and increased accessibility of scanners, longitudinal patient studies have increased in their number of CT and MRI scans, making their interpretation more challenging and time-consuming. While numerous AI and deep learning based methods have been developed for medical image analysis, they fail short of providing a viable solution for radiological follow-up.
In this talk, we present a novel fully automatic end-to-end pipeline for the comprehensive detection and segmentation of cancer lesions and the analysis of their evolution over time. The key novelties are: 1) SimU-Net, a simultaneous multi-channel 3D deep learning model trained on pairs of registered scans of each patient that identifies the lesions and their changes based on the lesion and healthy tissue appearance differences; 2) a model-based bipartite graph lesions matching method for the analysis of lesion changes at the lesion level; 3) a method for longitudinal analysis of consecutive scans of a patient based on SimU-Net. We demonstrate the method with experimental studies on liver and lung metastases in CT scans and brain metastases in MRI scans that establish state-of the-art results.
