About
Ashu Abhishek is a radiation oncology researcher whose work centers on precision and motion management in stereotactic radiosurgery (SRS) and stereotactic body radiotherapy (SBRT). His major contributions lie in quantifying and mitigating intrafraction motion—the subtle patient movements that occur during treatment—to improve targeting accuracy. In his most cited work (12 citations), he analyzed intrafraction motion in frameless, mask-based CyberKnife stereotaxy using 6D-skull tracking, providing critical data that helps clinicians set appropriate treatment margins and ensure safe delivery of high-dose radiation to intracranial targets. This study directly informs clinical protocols for patients receiving frameless SRS. Abhishek also contributed to the expanding role of SBRT beyond the brain, co-authoring an early report on CyberKnife fractionated radiotherapy for adrenal metastases (2 citations), demonstrating the technique’s potential for achieving durable disease control in extracranial sites. His work bridges the gap between technological capability and clinical application, offering evidence that supports the safe adoption of non-invasive, high-precision radiotherapy. For students and researchers, Abhishek’s research underscores the importance of rigorous motion analysis in making advanced radiosurgery both safer and more accessible.
