An Optimization Approach for Radiosurgery Treatment Planning
We outline a new approach for radiosurgery treatment planning, based on solving a series of optimization problems. We consider a specific treatment planning problem for a specialized device known as the Gamma Knife, that provides an advanced stereotactic approach to the treatment of tumors, vascular malformations, and pain disorders within the head. The sequence of optimization problems involve...
متن کاملTreatment Planning for Image-Guided Robotic Radiosurgery
Radiosurgery is a non-invasive procedure that uses focused beams of radiation to destroy brain tumors. Treatment planning for ra-diosurgery involves determining a series of beam conngurations that will destroy the tumor without damaging healthy tissue in the brain, particularly critical structures. A new image-guided robotic radiosurgical system has been developed at Stanford University in a jo...
متن کاملInverse treatment planning for Gamma Knife radiosurgery.
An inverse treatment planning system for Gamma Knife radiosurgery has been developed using nonlinear programming techniques. The system optimizes the shot sizes, locations, and weights for Gamma Knife treatments. In the patient's prescription, the user can specify both the maximum number of shots of radiation and a minimum isodose line that must surround the entire treatment volume. After satis...
متن کاملTreatment Planning for Self-Shielded Radiosurgery
A five degree of freedom, robotic, radiosurgical system dedicated to the brain is currently under development. In the proposed design, the machine is entirely self-shielded. The main advantage of a self-shielded system is the simplification of the system's installation, which can reduce the cost of radiosurgery. In this way, more patients can benefit from this minimally invasive and highly effe...
متن کاملEvaluation of a dedicated brain metastases treatment planning optimization for radiosurgery: a new treatment paradigm?
PURPOSE To investigate the feasibility of a novel dedicated treatment planning solution, to automatically target multiple brain metastases with a single isocenter and multiple inversely-optimized dynamic conformal arcs (DCA), and to benchmark it against the well-established multiple isocenter DCA (MIDCA) and volumetric modulated arc therapy (VMAT) approaches. MATERIAL AND METHODS Ten previous...
