A single-optical kernel for a phosphor-screen-based geometric QA system (RavenQA < sup > TM < /sup > ) as a tool for patient-specific IMRT/VMAT QA.

Conclusions: It is feasible to perform the patient-specific IMRT/VMAT verification with a single kernel using a commercially available phosphor-screen-based mechanical QA device in accordance with AAPM TG-142. It is also practical to implement since it only requires to measure the optical intensities of the field centers of several square fields, in order to obtain the OSK. &#13.
