RADIOTHERAPY SYSTEM INTEGRATING A RADIATION SOURCE WITH A MAGNETIC RESONANCE IMAGING APPARATUS WITH MOVABLE MAGNET COMPONENTS

摘要

Various embodiments are described herein for a Radio-Therapy (RT) system and an associated method and in particular to an integrated radiation source with an MRI system featuring a variable imaging Field Of View (FOV). The FOV can be tailored for various RT-specific applications such as, but not limited to, patient setup verification and real-time tumor tracking, for example, as well as for various imaging volumes of interest.

主权项

1. An MRI system for generating MR images of a volume of interest from an object, wherein the MRI system comprises:
an operator unit for controlling the operation of the MRI system; and an MRI scanner coupled to the operator unit and configured to perform MRI imaging of the volume of interest, the MRI scanner including:
interface circuitry for coupling to the operator unit;at least one moveably adjustable magnetic component that can be moved to different positions relative to the volume of interest for performing different MR imaging of the volume of interest; anda magnet positioning assembly that is coupled to the at least one moveably adjustable magnetic component to move the at least one moveably adjustable magnetic component to one of the different positions.
