摘要： A system for monitoring radiation treatment images Cherenkov emissions from tissue of a subject. A processor of the system determines densities of a surface layer of the subject from 3D images of the tissue to determine correction factors. The processor uses these factors to correct the Cherenkov images for attenuation of Cherenkov light by tissue, making them proportional to radiation dose. In embodiments, the system obtains reflectance images of the subject, determines second correction factors therefrom, and applies the second correction factors to the Cherenkov emissions images. In embodiments, the corrected images of Cherenkov emissions are compared to dose maps of a treatment plan. A method of correcting Cherenkov emissions images includes determining tissue characteristics from CT or MRI images in a surface volume where Cherenkov is expected, using; imaging Cherenkov emissions; and using the tissue characteristics to correct the images for variations in Cherenkov light propagation through the tissue.

摘要： Particle radiation therapy and planning utilizing magnetic resonance imaging (MRI) data. Radiation therapy prescription information and patient MRI data can be received and a radiation therapy treatment plan can be determined for use with a particle beam. The treatment plan can utilize the radiation therapy prescription information and the patient MRI data to account for interaction properties of soft tissues in the patient through which the particle beam passes. Patient MRI data may be received from a magnetic resonance imaging system integrated with the particle radiation therapy system. MRI data acquired during treatment may also be utilized to modify or optimize the particle radiation therapy treatment.

摘要： Various approaches for disrupting target tissue for treatment include identifying a target volume of the target tissue; causing disruption of the target tissue in a region corresponding to the target volume so as to increase tissue permeability therein; computationally generating a tissue permeability map of the target volume; and based on the tissue permeability map, computationally evaluating the disruption of the target tissue within the target volume.

摘要： A reconstructed volume of a region of patient anatomy is processed to reduce motion artifacts in the reconstructed volume. Autosegmentation of high-contrast structures present in an initial reconstructed volume is performed to generate a 3D representation of the high-contrast structures. 2D mask projections are generated by performing forward projection on the 3D representation, where each 2D mask projection includes location information indicating pixels that correspond to the high-contrast structures during the forward projection process. The acquired 2D projections are modified via in-painting to generate corrected 2D projections, where the acquired 2D projections are modified using information from the 2D mask projections. For example, pixels in the acquired 2D projections that are associated with high-contrast moving structures are replaced with low-contrast pixels. These corrected 2D projections are used to produce an improved reconstructed volume with fewer and/or less visually prominent motion artifacts.

摘要： Described herein are methods for beam station delivery of radiation treatment, where the patient platform is moved to a series of discrete patient platform locations or beam stations that are determined during treatment planning, stopped at each of these locations while the radiation source rotates about the patient delivering radiation to the target regions that intersect the radiation beam path, and then moving to the next location after the prescribed dose of radiation (e.g., in accordance with a calculated fluence map) for that location has been delivered to the patient.
