    Abstract: 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.

    Abstract: Systems, methods, and computer software are disclosed that can include receiving a treatment prescription for a patient, obtaining a diagnosis-driven magnetic resonance imaging guided radiotherapy treatment and planning workflow (MRgRT&P workflow) associated with the treatment prescription from a workflow library, the diagnosis-driven MRgRT&P workflow having a parameter list comprising parameters utilized for MRI-guided radiation therapy. With the diagnosis-driven MRgRT&P workflow, any of the following can be performed: imaging with the MRI-guided radiation therapy system utilizing radiation therapy imaging parameters in the parameter list, generating a radiation therapy treatment plan utilizing radiation therapy planning parameters in the parameter list, and/or controlling an MRI-guided radiation therapy system utilizing radiation therapy delivery parameters in the parameter list.

    Abstract: A radiofrequency receive coil assembly can include a first conductive loop and a second conductive loop electrically connected at a node. The first and second conductive loops can extend into a treatment beam region of the radio frequency receive coil assembly through which one or more beams of ionizing radiation pass. The first conductive loop and the second conductive loop can overlap each other to provide electromagnetic isolation and/or can use a common conductor combined with a shared capacitor to provide electromagnetic isolation, with the shared capacitor or other electrical components, as well as any conductive loop overlaps, being positioned outside of the treatment beam region. These features can, among other possible advantages, minimize and homogenize attenuation of the beams of ionizing radiation by the radiofrequency receive coil assembly.

    Abstract: A system including a diagnostic-quality CT scanner for imaging a patient, the diagnostic-quality CT scanner having an imaging isocenter and a radiation therapy device positioned adjacent the diagnostic-quality CT scanner, the radiation therapy device including a gantry carrying a radiation therapy beam source and having a radiation therapy isocenter separate from the imaging isocenter of the diagnostic-quality CT scanner. The system including a couch configured to position the patient for imaging and for radiation therapy by translating the patient between the diagnostic quality CT scanner and the radiation therapy device.
