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...

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...

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...

It is recommended that a significant number of the seed sources for low-dose-rate permanent brachytherapy (BT) be assayed and their source strengths validated against those stated by the manufacturer before seed implantation. The...

Accurate dose accumulation in cervical cancer radiotherapy combining external-beam radiotherapy (EBRT) and High-Dose-Rate brachytherapy (HDR) requires reliable Deformable-Image-Registration (DIR) between two drastically different...

Many of the mathematical principles used in medical physics such as geometric reasoning, exponential decay, iterative improvement, and basic probability originate from concepts introduced in high school. This study illustrates ho...

To evaluate long-term calibration stability and measurement uncertainty in reference dosimetry systems through systematic intercomparison analysis, establishing evidence-based quality assurance recommendations for radiation oncol...

Ring applicators are widely used in high-dose-rate (HDR) brachytherapy, where accurate source positioning is essential for achieving dosimetric precision. Following each radioactive source exchange, positional accuracy is routine...

To develop and evaluate a treatment planning method for the Venezia HDR applicator that utilizes interstitial needles to enhance High Risk Clinical Target Volume (HRCTV) coverage and reduce dose to organs at risk (OARs) through a...

As HDR Brachytherapy has the potential to increase in popularity due to changes in reimbursement models, the potential of new treatment sites for the modality can be increased through increased oargan-at-risk sparing via integrat...

The primary objective of this study is to evaluate the clinical application of the ROSA robotic system in facilitating high-precision interstitial applicator placement for patients with Glioblastoma Multiforme (GBM), ensuring tar...

This study details the formal acceptance testing and clinical validation of the Elekta/Nucletron Geneva gynecological HDR applicators. The objective was to establish a standardized commissioning framework to verify physical integ...

Episcleral plaque brachytherapy is the standard eye-preserving treatment for medium-sized ocular melanoma (OM), yet dosimetric evaluation remains challenging due to steep dose gradients, plaque curvature, and anisotropic source g...

High dose rate (HDR) brachytherapy is a well-established modality for treating prostate cancer. Imaging used for treatment planning is typically transrectal ultrasound (TRUS) or CT. This study aims to compare the volumetric accur...

We aim to compare cervical cancer brachytherapy treatment plans created using custom 3D-printed patient-specific cylindrical templates (PSCTs) to commercially available hybrid interstitial applicators (Geneva/Venezia, Elekta).

Brachytherapy is a standard component in cervical cancer treatment. Venezia applicators allow addition of limited needle positions to tandem and ovoid procedures, but needle selection and insertion depth largely rely on physician...

To develop a simple protocol for dose verification of Leipzig surface HDR applicators using Gafchromic EBT3 film.

Cervical cancer remains a major global health burden, with Image-guided High-Dose-Rate Brachytherapy (HDR-BT) serving as a critical treatment modality. While MRI is the gold standard for defining the Gross Tumor Volume (GTV), Hig...

The goal of this study is to develop a simple treatment planning system (TPS) to assess the dosimetry of a Y-90 source train-based treatment for intravascular brachytherapy (IVBT) using data from Monte-Carlo simulations.

To evaluate dosimetric characteristics and biological dose delivered via abbreviated regimen combining single-fraction HDR brachytherapy (15 Gy) with ultra-hypofractionated elective pelvic radiation therapy (ePUHRT, 25 Gy in 5 fr...

To determine the dosimetric impact of 3D-printed patient-specific cylindrical templates (PSCTs) printed with Formlabs Biomed Clear (BC) resin in gynecologic (GYN) high-dose-rate brachytherapy (HDRBT), and to validate clinical int...

Commercial cylindrical applicators used for vaginal brachytherapy may not always ensure sufficient contact with the vaginal mucosa, particularly in patients with reduced tissue compliance, leading to air gaps and dose uncertainty...

To compare and evaluate the benefit of having dual activity on LDR prostate implants as opposed to one single activity to either decrease dose in organs at risks (OARs) urethra and rectum or increase dose to inaccessible areas as...

To quantify the geometric accuracy of an automatic applicator anchor point placement framework for cervical cancer (CC) high-dose-rate (HDR) brachytherapy implemented in Oncentra Brachy (Elekta).
