Abstract: A method for high-dose Grid radiotherapy utilizing a three-dimensional (3D) dose lattice formation is described herein. The 3D dose lattice can be achieved by, but not limited to, three technical approaches: 1) non-coplanar focused beams; 2) multileaf collimator (MLC)-based intensity modulated radiation therapy (IMRT) or aperture-modulated arc; and 3) heavy charged particle beam. The configuration of a 3D dose lattice is comprised of the number, location, and dose of dose vertices. The optimal configuration of a 3D dose lattice can be achieved by manual calculations or by automating the calculations for a generic algorithm. The objective of the optimization algorithm is to satisfy three conditions via iteration until they reach their global minimum. With 3D dose lattice, high doses of radiation are concentrated at each lattice vertex within a tumor with drastically lower doses between vertices (peak-to-valley effect), leaving tissue outside of the tumor volume minimally exposed.

Abstract: Disclosed herein are systems, methods, and computer-readable storage devices for manufacturing patient-specific bolus for use in targeted radiotherapy treatment. Based on dose calculations without a bolus and based on three-dimensional scan data of a patient, the example system generates a model of a bolus for targeting radiotherapy treatment to a planning target volume or target region within the patient. The system can perform several iterations to generate a resulting model for the bolus. Then, the system can generate instructions for controlling a three-dimensional printer to generate the bolus that conforms to the patient's skin surface while also specifically targeting the planning target volume for the radiotherapy treatment. In this way, the amount of radiotherapy treatment administered to other tissue is reduced, while the costs, time, and human involvement in creating the bolus are significantly reduced.
