Seminar „Between physics, biology and medicine”

The seminar „Between physics, biology and medicine” is dedicated to the presentation of the latest achievements and research in the field of biophysics and medical physics. The hosts of the seminar are prof. Ewa Ł. Stępień, the head of the Department of Medical Physics, and prof. Paweł Moskal, the head of the Department of Experimental Particle Physics and Applications. The seminar is organized regularly every other Wednesday at 16:15 in lecture hall A-1-08.

The speakers of the seminar are invited guests from polish and foreign universities, our collaborators, scientists interested in application of physics in medical and biological research.

Photon-detecting imaging technologies play a crucial role both in diagnostics for nuclear medicine as well as for different tumour therapy modalities. Advanced techniques aim at exploiting the kinematical constraints of Compton scattering in a so-called Compton camera. In particle therapy there is a strong need for an in-vivo beam range verification in order to allow for reducing presently applied safety margins around the tumor volume, compromising the potential high precision of the treatment modality. Compton cameras aim at tracking the origin of (multi-MeV) prompt photons generated in the interaction of the therapeutic particle beam with tissue. In nuclear medicine, PET-based diagnostics could be enhanced in sensitivity by widening the scope of applicable radioisotopes to those β+ emitters which emit a third, prompt photon from an excited state of the β+-decay daughter nucleus. Registering the trajectory of this third photon with, e.g., a Compton camera in coincidence to the 511 keV annihilation photons leads to what is called ‘Whole Gamma Imaging (WGI)’ or ‘γ-PET’. Also, hybrid detector systems could be designed, e.g., to combine PET with Compton imaging. The presentation will describe the principle of Compton imaging and present the status and perspectives of ongoing developments on the Compton camera prototype under construction at LMU Munich.
