CAMPEP Reaccreditation Granted
(2018-01-12) The Duke University Medical Physics Graduate Program has received a five-year reaccreditation through December 2022 from the Commission on Accreditation of Medical Physics Education Programs (CAMPEP). CAMPEP is a nonprofit organization which offers accreditation of graduate and residency programs to ensure and promote quality education of medical physicists. We would like to especially thank and congratulate our faculties, staff members, and students for contributing to this successful effort!
3D Dosimetry Protocol for MRgIMRT
(2018-01-12) A paper by Stewart Mein (MS 2016), Leith Rankine (PhD 2019), Dr. Mark Oldham (Radiation Oncology), along with collaborators from Washington University at St. Louis and Rider University, titled “Development of a 3D remote dosimetry protocol compatible with MRgIMRT,” was recently featured in the Medical Physics Web. The paper discusses the development of a high-resolution 3D remote dosimetry protocol to verify MR-guided radiotherapy (MRgIMRT) treatments using PRESAGE. MR-guided radiotherapy uses permanent high-strength magnetic field which further complicates treatment verification. While most conventional dosimeters do not work in high magnetic fields, PRESAGE is a chemical dosimeter which is unaffected by the magnetic field presence and enables true high-resolution 3D dosimetry. This new PRESAGE formulation also allows dosimeters to be shipped and stored at room temperature throughout the protocol. For more information: http://medicalphysicsweb.org/cws/article/research/70722
Johnson Named 2017 Distinguished Investigator

Allan Johnson, PhD (Radiology) was recently named as one of the 19 researchers to receive the 2017 Distinguished Investigator Award from the Academy for Radiology and Biomedical Imaging Research. Over the past few decades, the radiology research community has been responsible for many important advances that have had a profound impact on healthcare. This prestigious honor recognizes and awards individuals for their accomplishments in the field of medical imaging and academic radiology. Click here to read more.
AuntMinnie Reports Duke Research
(2017-12-15) Dr. Ranish Khawaja, along with Dr. Gary Schooler and Dr. Ehsan Samei from Duke Radiology recently presented during RSNA meeting 2017 about their development of an automated image quality assessment tool for pediatric radiographs based on 10 perceptual attributes of adult chest radiographs, such as lung gray levels, lung details, rib-lung contrast, and mediastinum. Traditionally, image quality has relied on just a few physical measures such as noise and contrast, while observer studies are highly subjective by nature. This adaptation improved the performance of the algorithm, which now can be used for a variety of applications beyond image quality assessment, including protocol development, quality monitoring, and integration with dose estimates to improve benchmarks for pediatric chest radiography. The group also plans to explore whether machine learning could be used for the application. Click here to read more.
