Quality control (QC), according to ISO definitions, represents the most basic level of quality. It is considered to be the snapshot of the performance or the characteristics of a product or service, in order to verify that it complies with the requirements. Although it is usually believed that "the role of medical physicists in Diagnostic Radiology is QC", this, not only limits the contribution of medical physicists, but is also no longer adequate to meet the needs of Diagnostic Radiology in terms of Quality...

Assessments of the extent of knowledge in a domain can be important since non-identified lack of knowledge may lead to decisions that do not consider the effect of relevant factors. Two studies examined experts' and novices' perception of their own ignorance and knowledge out of everything there is to know within their own and other disciplines and their assessments of their discipline's, and other disciplines' knowledge of all there is to know in each discipline. In total 380 experts and 401 students from the disciplines of history, medicine, physics, and psychology participated...

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...

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...
