Treating multiple oligometastatic lesions typically requires creating separate SBRT plans, resulting in longer treatment time and an increase in planning complexity. In this work we evaluate biology-guided multi-target treatment (MTT) approach for a PET-linea...

Patient coaching on the Elekta Unity MR-Linac is challenged by an enclosed bore that limits direct observation and by high acoustic noise during MR imaging that can reduce comprehension of verbal commands. We developed a synchronized, dual-interface visual co...

Online adaptive prostate MR-guided radiotherapy (MRgRT) is time-sensitive, and contouring with structure preparation can require upwards of 15 minutes per fraction. While vendor-TPS provided contours can be useful, performance and consistency vary by site, pr...

Lattice radiotherapy (LATTICE) is a spatially fractionated technique that delivers high doses to discrete peak regions within the target while maintaining lower doses in surrounding valley regions, yielding a high peak-to-valley dose ratio (PVDR). Conventiona...

To compare MR-simulation motion emulation with measured respiratory gating performance for ultra-central lung treatments on 1.5T MR-linac and to identify the dominant factors affecting gating efficiency. The study focuses on the role of tracking surrogate sel...

Lattice stereotactic body radiation therapy (Lattice SBRT) delivers spatially fractionated high-dose vertices embedded within a lower-dose tumor base, producing steep dose gradients potentially sensitive to interfractional anatomical change. This study evalua...

Direct-to-unit (DTU) radiotherapy, which bypasses CT simulation and prospective planning, offers an opportunity to markedly shorten the interval from consultation to treatment and expand access to timely breast cancer care. Building on prior feasibility work,...
