CyberKnife Stereotactic Radiosurgery for Cholangiocarcinoma

open access: yesInternal Medicine, 2018
Cholangiocarcinoma is a devastating cancer with a poor prognosis. Patients are often diagnosed at the advanced stage, and curative surgery is impossible. Radiation therapy is used for cases of advanced cancer. A 50-year-old woman with stage IVb intrahepatic cholangiocarcinoma was diagnosed with unresectable cancer, and had chemotherapy; however, the ...

A pathway away from measurement‐based patient‐specific QA: A review of contemporary quality assurance for external‐beam radiotherapy sub‐systems

open access: yesJournal of Applied Clinical Medical Physics, Volume 26, Issue 12, December 2025.
Abstract Background Prior to the development of the IMRT and VMAT treatment techniques the quality assurance (QA) paradigm was one of routine linac QA supplemented by plan specific independent Monitor Unit checks and manual checks of data transfer.

Single-Isocenter Volumetric Modulated Arc Therapy vs. CyberKnife M6 for the Stereotactic Radiosurgery of Multiple Brain Metastases

open access: yesFrontiers in Oncology, 2020
Introduction: Stereotactic radiosurgery (SRS) is becoming more frequently used for patients with multiple brain metastases (BMs). Single-isocenter volumetric modulated arc therapy (SI-VMAT) is an emerging alternative to dedicated systems such as ...

Feasibility of markerless real‐time tumor tracking volumetric modulated arc therapy using diaphragm‐based respiratory offset vectors

open access: yesMedical Physics, Volume 52, Issue 12, December 2025.
Abstract Background Real‐time tumor tracking (RTTT) is an effective strategy for managing respiratory motion during radiation therapy; however, it typically requires invasive fiducial markers. As a non‐invasive alternative, markerless RTTT (ML‐RTTT) has gained increasing interest, especially with the growing use of volumetric modulated arc therapy ...
