  • Patent number: 11813105
    Abstract: 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.

  • Publication number: 20230126392
    Abstract: A novel method and a related system are configured to place measured trajectories into a voxel space, which moves with respect to a particle detector system. The trajectories are measured in a detector reference frame. The voxel space, typically fixed with respect to the object being imaged, is tracked optically with markers and a camera system. A decipherable correlation is established between a set of markers and a set of detector elements. This correlation provides coordinate transformation definitions to place the trajectories into the voxel space in medical imaging, treatment planning, and/or therapeutic applications. The novel method provides a clever process to register an optical tracking system with a particle detector system, which improves quality assurance, accuracy, speed, and operating cost efficiencies of ion, particle, and/or radiation-based imaging, treatment planning, or therapies. This novel method may be utilized in proton imaging, helium imaging, other ion-based imaging, or x-ray imaging.

  • Patent number: 6459085
    Abstract: A device and method for determining the x- and y-positions, as well as the depth of interaction, of an interaction between a gamma ray and a scintillation crystal. In one embodiment, a first and a second sensor array are disposed on opposite sides of a scintillation crystal which is subjected in incident gamma radiation resulting in the release of photons. The first sensor array provides a measurement of the x- and y-positions of the interaction while the second sensor array provides a measurement of the depth-of-interaction. In one embodiment, the first sensor array is a photomultiplier array and the second sensor array is an array of wavelength-shifting fibers.
