Teams Description

VisAGeS U746

This research unit is part of the University of Rennes I, jointly affiliated to INRIA (National Institute of Research in Computer Sciences and Automation) and INSERM (National Institute of Health and Scientific Research). It belongs to the IRISA Institute (UMR CNRS 6074) and is located in Rennes, France.

VisAGeS activities are focused on the research and development of new algorithms in medical imaging, information processing and computer assisted intervention in the context of the pathologies of the central nervous system. In this context, we are addressing the general problems of conception of the surgical room of the future, the better understanding of normal and pathological brain organs and systems behavior, at different scales, and the promotion and the support of Virtual Organizations of biomedical actors by means of healthgrid’s technologies.

The medical application objectives are focused on pathologies of the central nervous system, with a particular effort on extraction of new imaging biomarkers for brain pathologies (e.g. Multiple Sclerosis, neuropediatrics, strokes, psychiatry, …) and in Image Guided Neurosurgery through the integration of new intra-operative sensors and the semantic modeling of surgical procedures. More generally, our application objectives concern Multiple sclerosis, epilepsy, dementia, neuro-degenerative brain diseases, brain vascular diseases, Deep Brain Stimulation, and tumor surgery.

Neurinfo Platform

The Neurinfo platform is currently conducted by the VisAGeS team. It offers resources for image acquisition, handling and processing in clinical, methodological and technological R&D. This facility covers in vivo human imaging and neuroinformatics, notably in the setting of nervous system disease. Neurinfo’s goal is to contribute to a better understanding of the healthy and diseased human brain. Neurinfo strives to integrate clinical research projects from the image to the patient and perform technology transfer of image processing methods to the clinic. Neurinfo is currently equipped with a 3T MRI system located at Rennes University Hospital. It is operated by dedicated technical staff with expertise in the field of MRI physics and image processing, in collaboration with staff from the University Hospital’s Radiology Service. The Neurinfo platform promotes networking between the various stakeholders in medical imaging. It is open to a broad community of medical and scientific users on the regional, national and international levels

Computational Radiology Laboratory

The Computational Radiology Laboratory (CRL) is a computer science oriented laboratory in the Department of Radiology at Children’s Hospital. Faculty in the CRL have appointments at Harvard Medical School, and work closely with colleagues at Brigham and Women’s Hospital, Massachusetts General Hospital and Massachusetts Institute of Technology.

The CRL was founded in 2001 with the mission of improving our understanding of the structure and function of the brain and other organs of the human body, in order to improve our capacity to diagnose and treat disease. Members of the CRL achieve this by developing novel technologies and computational modelling strategies for understanding and interpreting radiological images.

The CRL has dedicated facilities, office space, computer and peripheral equipment, as well as access to resources including high performance supercomputers, a high performance network and medical imaging devices including PET, SPECT, CT and 1.5T and 3.0T MRI scanners.  The CRL has dedicated file servers with a combined total of over 12 terabytes of online storage, providing rapid access to data and a capacity to simultaneously analyze large databases of imaging data. The local network of the radiology department at Children’s Hospital is connected by fiber optic links operating at 1 Gigabit per second, and are all connected to Harvard Medical School, which is a gateway to the Harvard University network and the internet. It provides an efficient network to store and process the imaging data.

Magnetic Resonance Imaging at Boston Children’s Hospital

The magnetic resonance (MR) facilities at Boston Children’s Hospital and satellite sites in Waltham, Peabody and Lexington consists of three 1.5 Tesla scanners (one Siemens, one Philips, one General Electric) and four 3.0T Siemens (two Trio, one Verio, one Skyra) MRI scanners. All of the scanners are maintained with up-to-date software and hardware upgrades and research programming capabilities. These scanners are on-site at the Boston Children’s Hospital site.  Children’s Hospital has installed an intraoperative 1.5T MRI system, known as the MR-OR, the first and only system of its kind at a pediatric hospital in the country. Developed by IMRIS, the iSPACE surgical imaging suite captures digital images through a unique, ceiling-mounted, movable MRI scanner that can be used to take high-resolution, real-time patient scans before, during and after a surgical procedure. Each of the scanners is equipped with the latest multi-channel coils. We have dedicated pediatric head coils and hardware motion tracking to facilitate pediatric imaging.  Furthermore, we have just completed installation of a 7T Bruker animal MRI scanner.
