Chris Wagner: The role of Eden Radioisotopes in the future of nuclear medicine
Chris Wagner has more than 40 years of experience in nuclear medicine, beginning as a clinical practitioner before moving into leadership roles at companies like Mallinckrodt (now Curium) and Nordion. His knowledge of both the clinical and the manufacturing sides of nuclear medicine laid the groundwork for helping to found Eden Radioisotopes, a start-up venture that intends to make diagnostic and therapeutic raw material medical isotopes like molybdenum-99 and lutetium-177.

A type of “phase-space discontinuous diamond” difference scheme, or “phase-space linear discontinuous finite element” approximation, is implemented to solve the two-dimensional [(x-y) or (r-z)] neutron transport equation. The results obtained on some well-known transport benchmark problems are much more accurate than discrete ordinates solutions attained with spatial diamond differencing or discontinuous finite element approximations. Error studies show convergence to the phase-space fine-mesh limit solution with an approximate and convergence rate, at least in the case of rectangular cells on phase-space domain D × V. In addition, phase-space fine-mesh limit results have been estimated with the help of extrapolation procedures for some neutron transport benchmark problems. This phase-space linear discontinuous finite element approach can be easily enlarged to more general spaces.
