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.

Two new difference schemes are derived for numerically solving the transport equation in spherical geometry. The first difference method is positive; i.e., the calculated fluxes are never negative. Furthermore, for the first method, the error expansion is suitable for applying Richardson extrapolation with respect to both spatial and angular variables to increase the accuracy of the approximate fluxes. Numerical experiments illustrate the accuracy obtained using this procedure, as well as demonstrate that the accuracy of the second difference method is significantly improved through application of Richardson extrapolation. In addition, the numerical results indicate that the second method is significantly more accurate than the standard nonextrapolated diamond-difference method for numerically solving the transport equation in spherical geometry.
