The implications of the American Board of Radiology's decision to relinquish its specialty board designation on prospective authorized medical physicists (AMPs) and radiation safety officers (RSOs)

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract In order to independently supervise the medical use of byproduct material, physicists in the United States (US) must legally meet the qualifications defined by the Nuclear Regulatory Commission (NRC) in the 35th part of the tenth title of the Code of Federal Regulations (§ 10 CFR Part 35). The American Board of Radiology (ABR) relinquished its

Determination of appropriate energy threshold range for accurate estimation of effective atomic number considering statistical uncertainty in photon‐counting techniques

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose The energy threshold is an important parameter for precise material identification employing photon‐counting techniques. However, in such applications, the appropriate energy threshold has not been clarified. Therefore, we aimed to determine the appropriate energy threshold range for precise material identification, focusing on ...

Review of the application of dual‐energy CT combined with radiomics in the diagnosis and analysis of lung cancer

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Lung cancer is one of the most common malignant tumors in the world. Early detection and precise treatment are of great significance to clinical decision‐making and patient prognosis. As an emerging imaging technology, dual‐energy computed tomography (DECT) has increasingly prominent advantages in multi‐parameter and quantitative analysis in ...

Expert panel on monitoring radiation doses from recurrent medical diagnostic procedures: Sixth Gilbert W. Beebe Webinar

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Recurrent imaging is an essential tool for patient care but with an attendant dose from radiation exposure. Recurrent imaging has been the subject of increasing scrutiny and debate based largely on the risk from increasing cumulative doses. However, the accountability for and actions with recurrent imaging as a special component in the general

Dose rate correction of a diode array for universal wedge field dosimetric verification

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose To study the performance of MapCHECK 3 (MC3) in measuring universal wedge fields and propose a dose rate correction strategy to improve MC3 measurement accuracy. Materials and methods Universal wedge fields with different wedge angles and field sizes were measured at different depths using MC3.
