Open-faced thermoplastic masks are widely used for immobilization in stereotactic radiosurgery (SRS) to achieve submillimeter treatment accuracy. This study compared the performance of two commercially available mask designs for SRS patients: the dual-layer O...
Winston-Lutz (WL) testing is routinely used to assess coincidence between a linac’s mechanical and radiation isocenter. Although dedicated commercial phantoms exist for off-axis target verification, they require additional resources and training. The QUASARTM...
Craniospinal irradiation (CSI) can be delivered using a multi-isocentre technique. This requires a time-consuming alignment process using kV orthogonal imaging followed by cone-beam CT (CBCT) to ensure alignment accuracy across multiple anatomical regions. Su...
