Frameless, Virtual Cone Linac-Based SRS for Essential and Parkinsonian Tremor — the phase I/II prospective trial Dr. Thomas led as principal investigator, establishing incisionless thalamotomy on the modern linear accelerator.

Neurosurgery

VMAT vs. Gamma Knife for multiple cranial metastases — the plan-quality and delivery-time comparison that helped legitimize linac-based multi-metastasis radiosurgery.

Advances in Radiation Oncology

The virtual cone technique — co-developed method for generating tiny spherical dose distributions with a standard MLC, the basis of our frameless tremor treatments.
