Breast patients treated with intensity-modulated proton therapy (IMPT) often experience more severe skin dose toxicity compared to those with photon 3DCRT. Here we quantitatively estimated the LET-dependent RBE (LET-RBE) vs clini...

Neon ions (²⁰Ne) offer substantially higher clinically achievable dose-averaged linear energy transfer (LETd) escalation in the target compared to protons or carbon ions. LETd escalation has the potential to enhance biological ef...

To leverage 3-D surface guidance (SGRT) to investigate the relationship between lung volume and tracked surface area to be used for personalization and optimization of inhalation-based solid nanoparticle treatment simulations.

Kinase-substrate interactions are inherently directional: kinases phosphorylate substrates, not vice versa, yet most network-based methods ignore this asymmetry, potentially discarding predictive signal.1 We investigated whether...

Traditionally, shielding design in PET facility relies on manually interpolating semi-logarithmic transmission curves from NCRP 147 and AAPM TG 108. This process is time-consuming and varies depending on the user. This study intr...

To utilize data from a dose tracking software to retrospectively track repeat rates for frequently used CT exams

ACR CT Dose Index Registry (DIR) benchmarking is commonly reviewed at discrete reporting intervals, but single-interval interpretation can be limited by benchmark shifts, transient variation, or incomplete reference data. This st...

Clinical centres currently employ institution-specific methods for patient imaging (including imaging protocols and preprocessing methods), register, and store information. This lack of semantic standardization creates significan...

To develop and evaluate patient-specific, deep learning-based autocontouring models that incorporate planning and prior fraction images/contours for improved contouring of the prostate, bladder, and rectum in prostate adaptive ra...

To update COMP members on the implementation and adoption of lifecycle licences for radiotherapy licensees, and to highlight efficiencies realized through this regulatory framework. It will also outline planned improvements to li...

To determine the most radiobiologically consistent method for accumulating dose from differing treatment schedules for both targets and organs-at-risk in reirradiation scenarios.

Prostate stereotactic body radiation therapy (SBRT) requires high geometric precision due to large fractional doses and tight margins. Intrafraction prostate motion as large as 7–10 mm has been reported in extreme cases. CyberKni...

To evaluate the relationship between fat volume fraction (FVF) and Hounsfield units (HU) in unenhanced fatty lesions and to identify virtual monochromatic imaging (VMI) settings that minimize FVF quantification errors, by compari...

To study the accuracy and reproducibility of liver lesion volume measurements using fully automated lesion segmentation at virtual monochromatic imaging (VMI) with photon-counting and dual energy CT (PCCT and DECT).

Cancer treatment planning requires clinicians to rapidly synthesize complex clinical information from detailed patient notes, a process that is time-consuming and cognitively demanding, particularly in multidisciplinary workflows...

Optimize patient dose for Lung Cancer Screening (LCS) using local diagnostic reference levels (DRLs).

MR-guided radiotherapy, especially adaptive therapy, involves complex, multi-stage clinical workflows that are challenging to quantify using conventional manual metrics. In-depth, quantitative, understanding of the clinical workf...

In clinics operating multiple helical delivery systems, treatment plan transfer between machines is frequently desired to improve scheduling flexibility. Despite beam matching, vendor guidance commonly recommends repeating full p...

SRS MapCheck has been widely used for SRS pretreatment patient-specific quality assurance (PSQA); however, it requires multiple machine deliveries due to limited array size. To improve the pretreatment PSQA efficiency for Single...

Tumor hypoxia drives radio-resistance in Head & Neck cancer (HNC) and can guide radiation dose de-escalation. Tumor hypoxia can be imaged using 18F-fluoromisonidazole (FMISO-PET; non-standard-of-care). Because hypoxia drives glyc...

Grayscale ultrasound is widely used in breast screening, diagnosis, and ultrasound-guided biopsy, particularly for detecting breast lesions. However, current Quality Control (QC) methods provide limited and often subjective asses...

Ring artifacts were observed on our photon-counting CT (PCCT) daily quality control images, with 40 keV virtual monoenergetic images (VMIs) exhibiting the most pronounced artifacts. Because these artifacts may reflect degraded sy...

This presentation shares insights gained over 6 years of implementing a dose monitoring software for Computed Tomography (CT) exams across a large, multi-campus hospital. By sharing our experience, we aim to help other institutio...

A gamma camera is used as part of a standard process at nuclear medicine centers or hospitals to measure the glomerular filtration rate (GFR) in chronic kidney disease (CKD) cases. However, the gamma camera is not able to offer c...
