: The medical physics community has lost one of its great pioneers with the passing of John R. Cunningham O.C., B.Eng., M.Sc., Ph.D., FCCPM, FAAPM, FCOMP in Calgary, Alberta, Canada, where he lived most recently with his wife, Sheila Cunningham. He was known universally, simply as "Jack". He passed away on 04 January 2020, one day before his 93rd birthday, as a result of progression of prostate cancer.

Abstract Background With increasing recognition of growing cancer incidence globally, efficient means of expanding radiotherapy capacity is imperative, and understanding the factors impacting human and financial needs is valuable. Materials and methods A time-driven activity-based costing analysis was performed, using a base case of 2-machine departments, with defined cost inputs and operating parameters. Four income groups were analysed, ranging from low to high income. Scenario analyses includ...

The past few years have seen a significant growth of interest in the global radiation therapy (RT) crisis. Various organizations have quantified the need and are providing aid in support of addressing the shortfalls existing in many low-to-middle income countries. With the tremendous demand for new facilities, equipment, and personnel, it is very important to recognize the quality and safety challenges and to address them directly. An examination of publications on quality and safety in RT indic...

AbstractBackground: Radiotherapy technology continues to advance and the expectation of improved outcomes requires greater accuracy in various radiotherapy steps. Different factors affect the overall accuracy of dose delivery. Institutional comprehensive quality assurance (QA) programs should ensure that uncertainties are maintained at acceptable levels. The International Atomic Energy Agency has recently developed a report summarizing the accuracy achievable and the suggested action levels, for...

Purpose: There is an increasing awareness of the disparity in Medical Physics needs between high income countries (HICs) and low-to-middle income countries (LMICs). This is especially evident with the growing incidence of cancer in LMICs. Projections from the recent Lancet Oncology Commission on Expanding Global Access to Radiotherapy indicate that an additional 22,000 Medical Physicists will be required by 2035 to provide uniform access to radiation therapy globally. This paper addresses possib...
