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.

Method to register an optical tracking system with a particle detector system

A medical imaging system includes a first tracking detector and a second tracking detector. The tracking detectors are spaced to allow for an object to be present between the first tracking detector and the second tracking detector. The system also includes a residual range detector adjacent the first tracking detector. The residual range detector includes: (1) a scintillator material having a first surface at least partially covered with an anti-reflection material and a second surface facing the first tracking detector and (2) at least one photon detector coupled to the scintillator material at a third surface of the scintillator material different than the first surface and opposite the second surface.
