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...

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...

Prior to clinical launch of the world’s first installation of MEVION S250-FIT combined with Marie® system we evaluated anatomical and dosimetric differences between conventional photon-based supine treatments and proton-based upr...

To investigate whether the apparent diffusion coefficient (ADC) from diffusion-weighted imaging (DWI) acquired at a 0.35T MR-Linac can determine prostate and intraprostatic lesion changes caused by adaptive radiotherapy performed...

Radiomics features are increasingly used for quantitative image analysis; however, their robustness to image acquisition and reconstruction parameters remains a critical concern. Field of view (FOV) variations can alter image sam...

To develop and evaluate an automated, log-file–based MLC positional accuracy QA method for routine and longitudinal assessment of MLC performance on the ViewRay MRIdian MR-Linac system.

This study investigates a model for the auto-segmentation of cranial nerves in the context of radiosurgery treatment planning for acoustic neuroma and trigeminal neuralgia. Current treatment planning systems are unable to perform...

Prone breast treatment is a known approach in radiation therapy. In addition to the benefits in lowering the OAR dose, an MRI imaging to guide preoperative radiation can be used. A fixed beam Proton PBS using a flat table top wit...

Mammography (compressed 2D) and MRI (uncompressed 3D) capture breast tissue under different conditions, complicating tumor localization across modalities. To bridge this gap, we developed a customizable physical platform to simul...

Patients who undergo stereotactic body radiation therapy (SBRT) for lung cancer can present with contraindications, making it difficult to achieve tumoricidal coverage and adequate organs-at-risk (OAR) sparing. MRI guided-adaptiv...

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...

Contrast-enhanced CT (CECT) is routinely used in radiotherapy planning to improve visualization of tumors, lymph nodes, and vascular anatomy for accurate target delineation. However, contrast administration is contraindicated in...

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...

In conventional MRI, bone and air appear as signal voids due to signal decay, making them difficult to distinguish. This remains a major limitation for synthetic CT (sCT) generation in MRI-based radiotherapy. Although AI-based ap...

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...

This study designed SIB-IMRT plans based on pathologically confirmed positive LNs and compared them with conventional IMRT plans to evaluate the feasibility and dosimetric advantages of SIB-IMRT for rectal cancer patients with me...

This study aimed to evaluate the clinical feasibility of a dual-target 3D-motion tracking workflow for 0.35T MRI-guided stereotactic body radiotherapy (MRgRT) in upper abdominal targets. The focus was on implementing real-time, d...

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).

MRI‑guided linear accelerators (MR‑Linacs) enable real‑time adaptive radiation therapy by allowing daily plan adaptation based on anatomical changes. In pancreatic cancer, substantial interfraction motion and proximity to gastroi...

Due to the dose engine algorithm, there is a gap between Independent secondary dose calculation (ISDC) and the treatment planning system algorithm for small fields, inhomogeneity environment correction, and online adaptive plan Q...

MRI guided Adaptive Radiation Therapy (MRgART) allows for daily plan adaptation to the patient’s anatomy. This is achieved by imaging the patient before each fraction, editing the contours to the new anatomy, and adapting the pla...

To assess the dosimetric impact of systematic source position uncertainty along the source path during MRI-guided gynecological high-dose-rate (HDR) interstitial brachytherapy (ISBT) treatment planning.

Aim of study is to compare MPC output measurements with daily output measured by PTW Quick-Check and Ion chamber Based measurements for Varian Ture-Beam linear accelerator (LINAC).

To contour the PCMs utilizing MRI/CT image fusion technology and to evaluate the feasibility of PCM-sparing in proton therapy for NPC.
