Evaluation of internal target volume of abdominal tumors using cine‐MRI

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Introduction The detailed anatomy visualization with magnetic resonance (MR)‐guided radiotherapy is particularly attractive for abdominal treatments, but patient respiratory motion can compromise image quality. The “navigator technique” produces high‐quality 3D images, triggered by diaphragm displacement, in exhale phase only.

DICOM attribute manipulation tool: Easily change frame of reference, series instance, and SOP instance UID

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose In radiation oncology, the integration and registration of multiple imaging modalities is a crucial aspect of the diagnosis and treatment planning process. These images are often inherently registered, a useful feature in most cases, but possibly a hindrance when registration modifications are required.

Interfaces of Incompleteness

open access: yes, 2019
Science constructs tools for knowledge and, occasionally, this bold enterprise may let a few believe in the “completeness” of a given theoretical frames: as for these phenomena, we can predict, derive, compute ... everything. Yet, negative results, often based on the very tools proposed by the scientific approaches, set the limits to knowledge ...

Evaluating feature extraction reproducibility across image biomarker standardization initiative‐compliant radiomics platforms using a digital phantom

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Background The aim of this study was to thoroughly analyze the reproducibility of radiomics feature extraction across three Image Biomarker Standardization Initiative (IBSI)‐compliant platforms using a digital phantom for benchmarking. It uncovers high consistency among common features while also pointing out the necessity for standardization ...

Automated rapidplan model validation using Eclipse scripting API

open access: yesJournal 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
