To quantitatively compare image quality from HyperSight CBCT to dedicated CT Simulation scanners, using a standard image quality phantom and conventional imaging metrics to assess performance differences and their statistical significance.

This work introduces a framework to automate treatment planning of small-volume lattice radiotherapy applied to head and neck malignancies.

Modern radiation therapy incorporates advanced technologies including surface guidance, 6DoF couches, SRS, and combined-axis delivery. Traditional QA programs test these capabilities in isolation using multiple independent phantoms. This work characterizes a...

To evaluate the feasibility of HyperSight CBCT–based radiotherapy planning on the Varian Ethos v2.0 platform and to develop a clinically deployable simulation workflow that overcomes current system limitations.

VMAT based cerebrospinal irradiation (CSI) using photons has emerged as a palliative treatment approach for patients suffering from metastatic leptomeningeal disease. In this work we describe the experience introducing VMAT CSI into clinical use.
