Deep Multimodality Image-Guided System for Assisting Neurosurgery
This project focuses on addressing the challenges in brain tumor surgery, particularly gliomas, one of the most common malignant brain cancers. It emphasizes the need for precise tumor delineation and overcoming issues related to brain deformation during surgery. The project aims to develop an innovative peri-operative image-guided neurosurgery system called DeepIGN. This system involves various components, including a glioma segmentation module, multimodal image registration, explainability module, and an interactive neurosurgical display. These components have been extensively validated in the laboratory and simulated operating room, showing promising results. DeepIGN is designed as open-source research software to advance research in the field of neurosurgery and improve the treatment of brain tumors.

Multimodal CNN Networks for Brain Tumor Segmentation in MRI
In this project, the focus is on automating the segmentation of gliomas, which is crucial for diagnosing brain tumors, predicting disease progression, and planning patient therapy. The challenge lies in accurately detecting gliomas and their sub-regions in MRI scans, considering variations in scanners and imaging protocols. The project’s contribution to the BraTS 2022 Continuous Evaluation challenge involves an ensemble approach that combines three deep learning frameworks: DeepSeg, nnU-Net, and DeepSCAN. This ensemble achieved top rankings in both the BraTS testing dataset and an additional Sub-Saharan Africa dataset, with high Dice scores and low Hausdorff distances, showcasing its effectiveness in glioma boundary detection.

DeepSeg: deep neural network framework for automatic brain tumor segmentation using magnetic resonance FLAIR images
DeepSeg is a generic deep learning architecture for fully automated detection and segmentation of brain lesions using FLAIR MRI data. The developed modular framework includes a convolutional neural network (CNN) responsible for spatial information extraction (encoder). The resulting semantic map is inserted into the decoder part to get the full-resolution probability map.
