Abstract: A method for guiding resection of local tissue from a patient includes generating at least one image of the patient, automatically determining a plurality of surgical guidance cues indicating three-dimensional spatial properties associated with the local tissue, and generating a visualization of the surgical guidance cues relative to the surface. A system for generating surgical guidance cues for resection of a local tissue from a patient includes a location module for processing at least one image of the patient to determine three-dimensional spatial properties of the local tissue, and a surgical cue generator for generating the surgical guidance cues based upon the three-dimensional spatial properties. A patient-specific locator form for guiding resection of local tissue from a patient includes a locator form surface matching surface of the patient, and a plurality of features indicating a plurality of surgical guidance cues, respectively.

Abstract: A system for performing radiation treatment of a patient with a proton beam from a particle accelerator uses a high-sensitivity camera to capture dose images of patient surface, a video processor that integrates the dose images, beam-on detection apparatus, and apparatus to eliminate interference of room lighting. In embodiments, the system registers dose images to a surface model of the patient derived from stereo image pairs captured by a stereo camera. In embodiments, the surface model is registered to three-dimensional images of the patient from MRI or CT, and an integrated three-dimensional energy deposition map of the patient is prepared.

Abstract: A patient-specific device for guiding resection of a tumor located in local tissue of a patient includes a locator form and a surgical guidance cue. The locator form has a locator-form surface matching a surface of the local tissue of the patient near the tumor's location when the local tissue is imaged in a preoperative position, such that the locator form, when fit to the surface of the local tissue, restores the local tissue to the preoperative position. The surgical guidance cue is integrally formed with the locator form and based on images including only preoperative images of the local tissue in the preoperative position, to indicate a spatial property of the tumor in the preoperative position.

Abstract: A Cherenkov imaging system includes a high-speed radiation detector configured to provide a first timing signal synchronized with pulses of radiation to control operation of at least one pulse-gated, multiple-pulse-integrating, (PG-MPI) CMOS camera synchronized through the digital time signal to pulses of the radiation beam source, to image Cherenkov radiation; and a digital image-processing system. The high-speed radiation detector is either a solid-state radiation detector or a scintillator with a photodetector. The system images Cherenkov light emitted by tissue by using a timing signal synchronized to pulses of a pulsed radiation beam to control the PG-MPI camera by integrating light received by the PG-MPI camera during multiple pulses of the radiation beam while excluding light received by the camera between pulses of the radiation beam.
