Development of a residency program in radiation oncology physics: an inverse planning approach.

Over the last two decades, there has been a concerted effort in North America to organize medical physicists' clinical training programs along more structured and formal lines. This effort has been prompted by the Commission on Accreditation of Medical Physics Education Programs (CAMPEP) which has now accredited about 90 residency programs. Initially the accreditation focused on standardized and higher quality clinical physics training; the development of rounded professionals who can function at a high level in a multidisciplinary environment was recognized as a priority of a radiation oncology physics residency only lately.

Characterizing 3D printing in the fabrication of variable density phantoms for quality assurance of radiotherapy.

Purpose: To present characterization, process flow, and applications of 3D fabricated low density phantoms for radiotherapy quality assurance (QA).

Material And Methods: A Rostock 3D printer using polystyrene was employed to print slabs of varying relative electron densities (0.18-0.
