摘要： A collimating system for collimating a radiation beam having a first multileaf collimator and a second multileaf collimator configured such that the radiation beam will pass through the first multileaf collimator before passing through the second multileaf collimator, and pass through the second multileaf collimator before hitting its target. The leaves of the first multileaf collimator and the leaves of the second multileaf collimator may be configured to move independently of one another.

摘要： Magnetic resonance (MR) guided radiation therapy (MRgRT) enables control over the delivery of radiation based on patient motion indicated by MR imaging (MRI) images captured during radiation delivery. A method for MRgRT includes: simultaneously using one or more radiation therapy heads to deliver radiation and an MRI system to perform MRI; using a processor to determine whether one or more gates are triggered based on at least a portion of MRI images captured during the delivery of radiation; and in response to determining that one or more gates are triggered based on at least a portion of the MRI images captured during the delivery of radiation, suspending the delivery of radiation.

摘要： A system has a linear accelerator, ion pump and a compensating magnet. The ion pump includes an ion pump magnet position, an ion pump magnet shape, an ion pump magnet orientation, and an ion pump magnet magnetic field profile. The compensating magnet has a position, a shape, an orientation, and a magnetic field profile, where at least one of the position, shape, orientation, and magnetic field profile of the compensating magnet reduce at least one component of a magnetic field in the linear accelerator resulting from the ion pump magnet.
