Enhanced analysis of gating latency in 0.35T MR‐linac through innovative time synchronization of a motion phantom and plastic scintillation detector

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose This study aims to evaluate how different gantry angles, breathing rates (BPM), cine image speeds, and tracking algorithms affect beam on/off latency and the subsequent impact on target dose for a 0.35T MR‐Linac with a 6 MV FFF beam.

Energy dependence of the GAFCHROMIC LD‐V1 in the diagnostic radiographic modalities

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract The GAFCHROMIC LD‐V1 radiochromic film is widely used in dosimetry because it can provide high‐resolution two‐dimensional dose distributions without processing. This study aimed to evaluate the response characteristics at different effective energies, from the low‐energy range of mammography to the high‐energy range of computed tomography. Net

Automated rapidplan model validation using Eclipse scripting API

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract RapidPlan offers efficiency gains and quality improvements in treatment planning. Prior to its use in the clinic, it requires an extensive validation procedure in which established clinical plans and those generated by the model are compared. The manual iterative nature of this process is resource intensive, as numerous iterations are required

Towards better understanding of factors contributing to medical physicist well‐being in academic medical centers: A systems‐analysis approach

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract The well‐being of medical physicists can impact overall system performance, patient safety, and quality of patient care. There are limited formal assessments of factors contributing to physicists well‐being. Nine medical physicists at a US academic medical center were surveyed on 21 workplace factors, drawn from the National Academy of ...

THE NORMAL DISTRIBUTION [PDF]

Essentials of Pattern Recognition, 1991
The chapter begins by presenting a mathematical expression used to describe a model for the Normal or Gaussian distribution. In the absence of any other information, the Normal distribution is assumed to apply whenever repetitive measurements are made on a sample, or a similar measurement is made on different samples.

The Normal distribution [PDF]

BMJ, 2010
Researchers investigated whether antidepressant drug prescribing and referrals to specialist services for depression by general practitioners were associated with patients’ scores on depression severity questionnaires measured at the start of treatment. Anonymised data from the medical records of 38 general practices were investigated.
