Title: Richard J. Brunelli: Medical Radiation Therapy Inventions

Introduction

Richard J. Brunelli is an inventor associated with San Jose, California, and Varian Associates, Inc. His work includes inventions designed to improve radiation therapy equipment and treatment planning. He is credited with 2 patents.

Latest Patents

Brunelli’s patents address radiation compensation and electron beam collimation.

“Apparatus for Producing Tissue Compensating Filter for Use in Radiation” describes equipment for fabricating a compensating filter. A stylus traces a patient’s surface profile while a cutter shapes a form. Linkages coordinate their movements at a ratio that accounts for the difference between radiation absorption in the compensating material and in human tissue. The resulting mold is filled with compensating material to create the filter.

“Collimation System for Electron Arc Therapy” describes a system for shaping and shielding an electron beam during arc therapy. A movable slit collimator provides dose compensation in the sagittal direction, while a hoop-and-clamp assembly shapes the treatment field. The design aims to provide uniform shielding without placing the shielding material’s weight on the patient.

Career Highlights

Brunelli’s listed inventions focus on practical challenges in radiation therapy, including adapting dose distribution to patient anatomy and shaping electron treatment fields. His work at Varian Associates, Inc. connects these patented technologies with the development of medical radiation equipment.
