Automation and geometric verification tools are increasingly important in radiotherapy for non-coplanar stereotactic treatments. This study implements a patient-specific 3D modeling–based method to generate gantry–couch collision...
Ultrasound-guided high-dose-rate (HDR) interstitial prostate brachytherapy is a technically demanding procedure requiring proficiency in imaging, catheter reconstruction, contouring, treatment planning, and quality assurance unde...
Motion-related effects remain a critical source of uncertainty in proton and carbon ion therapy. Sharp dose gradients, combined with the inherent sensitivity of the particle range, make dose delivery particularly susceptible to t...
To evaluate the impact of four-dimensional CT (4D-CT) reconstruction methods on lung tumor volume estimation and apparent tissue density under respiratory motion using dynamic phantoms with diverse geometries.
A multi-institutional journal club (MIJC) was introduced by the AAPM’s Working Group on Multi-Institutional Journal Clubs for Residency Programs (WGJCRP) in 2021. As of 2022, 40% of therapy programs were participating. The MIJC p...
Independent Monte Carlo (MC) dose calculation of clinical pencil beam scanning (PBS) proton treatment plans requires conversion of beam spot monitor units (MU) into the number of protons transported in MC simulations. This conver...
Monte Carlo (MC) methods are widely regarded as the gold standard for radiotherapy dose calculation; however, high computational cost can limit routine clinical application. This study evaluated two jaw-interaction–based event-co...
To develop and validate a combined model, based on multi-sequence magnetic resonance imaging (MRI), integrating immune checkpoint molecular markers and multiple independent prognostic factors, to predict overall survival (OS) in...
The spread-out Bragg peak (SOBP) technique uses ridge filters to broaden the depth-dose profile, producing a dose distribution similar to a single-field-uniform(SFU) approach. In contrast, the single-energy pristine Bragg peak(SE...
This study aimed to enhance safety during system upgrades of radiation therapy equipment by developing a comprehensive risk management framework that incorporates Failure Mode and Effects Analysis (FMEA) and Quality Indicators (Q...
High-dose-rate (HDR) brachytherapy (BT) is characterised by steep dose gradients and high doses delivered per treatment fraction in a short time. These features, together with the numerous steps involved in treatment delivery, ma...
Monte Carlo (MC) methods are widely used for proton therapy dose calculation due to their high physical accuracy, but their stochastic nature results in statistical noise and long computation times, particularly for high-resoluti...
The growing adoption of Digital Twin (DT) technologies in healthcare highlights the need to define how medical imaging tools (physical and digital phantoms, real and simulated CT studies, etc.) integrate with the virtual componen...
To evaluate the planning feasibility of spiral volumetric modulated arc therapy (SVMAT) for preserving ovarian function in cervical cancer radiotherapy. The SVMAT technique, which integrates longitudinal couch movement, combines...
High linear energy transfer (LET) IMNT faces practical delivery constraints: low output rates (~55 MU/min), manual gantry and couch rotations (~3-5 min/field), and mandatory wait times (~1-2 min/field) for neutron activation conc...
Radiopharmaceutical therapy (RPT) plays an important role in the management of oncology patients, particularly those with thyroid cancer, prostate cancer, and neuroendocrine tumor. The use of radionuclide therapy has expanded rap...
Auto-contouring (AC) of the pelvic nodal Clinical Target Volume (CTV) for prostate cancer radiation therapy can reduce contouring time and inter-physician variability. A vendor tool provides two AC models based on different conto...
Automatic intensity-based CBCT registration for initial spine treatment setup is challenging due to the similar appearance of vertebral bodies (VBs), which can lead to misalignment. This study evaluated the feasibility of using A...
Leptomeningeal metastases (LM), or the spread of cancer to the cerebrospinal fluid, is a neurologically devastating manifestation of cancer. Without treatment survival is limited to months, and few effective therapies exist. A ra...
Shortages of trained medical physicists persist across Africa. Needs-assessment surveys were utilized to determine trainee interest and medical physics curricular gaps to aid in design of hands-on outreach workshops for the Afric...
The purpose of this research is to develop a method for extracting and processing PET/CT and planning CT (pCT) with dose distribution. This method aims to address the challenge of co-registering data from different imaging modali...
We evaluate the performance of a 4-channel plastic scintillator for real-time dose monitoring during VMAT total body irradiations (TBI).
Improve accessibility of Modulation Transfer Function (MTF) metrics for implementing routine quality control (QC) of fluoroscopes.
To compare dosimetry audit results for 6 MV flattening-filter-free (FFF) photon beams between conventional C-arm linear accelerators (linacs) and a ring-based architecture (O-ring) linacs using IAEA/WHO postal dosimetry audit res...
