Overall Effectiveness

Magnetic resonance (MR) imaging plays a central role in non-invasive focused ultrasound surgery in the brain, by providing maps of temperature during treatment. The temperature maps are used both to steer the ultrasound beam, and to measure thermal dose. However, current MR thermometry methods provide insufficient spatial coverage and suffer large distortions, which compromises patient safety and limits the overall effectiveness of the therapy. This project aims to develop a toolbox of brain temperature imaging sequences and processing algorithms that directly address the current shortcomings of MR thermometry at each stage of therapy.

The Way

Portable laser ablation is tested for Pb isotope analysis of silver, yielding results comparable to bulk analyses. This low impact method removes the need for invasive sampling, opening the way for analysis of archaeological silver worldwide.
