The goal of this report is to provide a framework from which an institution can develop a competency and credentialing program. It is not intended to be adopted as written, but rather as a list of suggestions from which the institution develops their program. A clear distinction should be made between the initial evaluation of the competency of new staff (credentialing) and the ongoing verification of the competency of existing staff. Furthermore, whenever new technologies are implemented, the entire staff would be subject to the credentialing process...

Carmel J Caruana, J Adam M Cunha, Colin G Orton
In addition to their clinical duties, many medical physicists find themselves in a situation where they have to do managerial work such as strategic planning and communication within a hospital or with outside agencies. Typically, these skills are obtained on-the-job or by taking extra-curricular courses. However, some believe that such strategic planning and communication and management skills are so important that courses on these topics should become an integral part of the medical physics curriculum. This is the claim debated in this month's Point/Counterpoint...

Clive Baldock, L John Schreiner, Colin G Orton
Medical physics is a rapidly developing, technologically dependent, field. New discoveries are being made almost daily, as demonstrated by papers in this and other similar journals. Many of the authors are early in their careers. Some are concerned, however, that more famous medical physicists often get credit for discoveries due to their fame rather than less prominent scientists who may have, in fact, contributed more to the development in question. This is the claim debated in this month's Point/Counterpoint...

Radiation dose monitoring solutions have opened up new opportunities for medical physicists to be more involved in modern clinical radiology practices. In particular, with the help of comprehensive radiation dose data, data-driven protocol management and informed case follow up are now feasible. Significant challenges remain however and the problems faced by medical physicists are highly heterogeneous. Imaging systems from multiple vendors and a wide range of vintages co-exist in the same department and employ data communication protocols that are not fully standardized or implemented making harmonization complex...
