Long‐term stability analysis of beam shape in a robotic radiosurgery system

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose This study aimed to investigate the long‐term stability of CyberKnife beam profile parameters and assess their compliance with existing quality assurance (QA) guidelines. We evaluated beam profiles in both standard and diagonal planes over 3.5 years post‐installation to detect potential issues and ensure consistent beam quality.

Dosimetric evaluation and clinical application of collimated apertures with proton beam line scanning in stereotactic radiotherapy

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Stereotactic radiotherapy (SRT) is a highly effective treatment with precision for small, localized lesions. Proton therapy, characterized by the Bragg peak, offers superior dose conformity compared to photon‐based approaches. However, challenges remain in minimizing lateral penumbra and optimizing dose delivery, particularly for small
