Reduction of artifacts in magnetic resonance imaging

Apparatuses, methods, and computer program products for reducing an appearance of an artifact in an image generated by a magnetic resonance imaging (mri) system are disclosed. The apparatus includes a magnetic field generating device configured to create an inhomogeneity in the magnetic field of an mri system and prevent at least one out-of-field excitation during imaging.. ... Viewray Incorporated

Radiation therapy systems and methods

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.. ... Viewray Incorporated

Assessment and improvement of treatment using imaging of physiological responses to radiation therapy

Edema in tissue of a patient undergoing a course of radiation therapy or treatment can be estimated based on one or more mri measurements used to measure changes in fluid content of various tissues. A correlation between observed changes in edema and one or more delivered fractions of radiation can be used to drive one or more clinical actions. ... Viewray Incorporated

Magnetic resonance imaging
