Gamma-MRI: towards high resolution single photon imaging using highly-aligned gamma-emitting nuclei

Video meeting
Gamma-MRI is a technique used for the detection of gamma ray emission of long-lived nuclear states with magnetic Resonance Imaging (MRI). It paves the way to a new medical imaging modality capable of overcoming the limitations of existing imaging techniques: spatial resolution and sensitivity.
Embarking on this study required a multistep approach and several milestones - of which a successful proof-of-concept experiment has recently been in the spotlight. The aim of that experiment was to optimize the degree of polarization for used isomers by observing changes in gamma decay anisotropy.
The experimental setups needed for the proof-of-concept experiment have been assembled, tested and verified. The radioactive Xe isotopes: 129mXe (t1/2 = 9 days) and 131mXe (t1/2 = 12 days), were produced at nuclear reactor in Grenoble (ILL), then transferred to MEDICIS and tested at ISOLDE with the assembled experimental setup.
The seminar will cover the progress that has been made so far in the project, primarily the progress made within the scope of the PhD.
