Patent number: 11813105Abstract: A computer-implemented system and method for generating a medical image is provided. In some embodiments, the medical image is generated by determining a location and an alignment for a first tracking detector with respect to a particle beam system. The direction of a beam generated from the particle beam system is determined. A first position of a first particle from a detected particle hit on the first tracking detector is also determined. A determination is made as to a first residual range of the first particle from a detected particle hit on a residual range detector. The system reconstructs a path for the first particle based on the location, the alignment, the first position, and the first residual range of the first particle. The resulting medical image that is generated by the system is based on the reconstructed path for the first particle.Type: GrantFiled: January 15, 2021Date of Patent: November 14, 2023Assignees: BOARD OF TRUSTEES OF NORTHERN ILLINOIS UNIVERSITY, PROTONVDA LLCInventors: Don F.
