METHODS AND SYSTEMS USING MAGNETIC RESONANCE AND ULTRASOUND FOR TRACKING ANATOMICAL TARGETS FOR RADIATION THERAPY GUIDANCE

摘要

Methods and systems using magnetic resonance and ultrasound for tracking anatomical targets for radiation therapy guidance are provided. One system includes a patient transport configured to move a patient between and into a magnetic resonance (MR) system and a radiation therapy (RT) system and an ultrasound transducer coupled to the patient transport, wherein the ultrasound transducer is configured to acquire four-dimensional (4D) ultrasound images concurrently with one of an MR acquisition or an RT radiation therapy session. The system also includes a controller having a processor configured to use the 4D ultrasound images and MR images from the MR system to control at least one of a photon beam spatial distribution or intensity modulation generated by the RT system.

1. A system comprising:
a patient transport configured to move a patient between and into a magnetic resonance (MR) system and a radiation therapy (RT) system; an ultrasound transducer coupled to the patient transport, the ultrasound transducer configured to acquire four-dimensional (4D) ultrasound images concurrently with an MR acquisition session and with a separate RT radiation therapy session; and a controller having a processor configured to use the 4D ultrasound images and MR images from the MR system to control at least one of a photon beam spatial distribution or intensity modulation generated by the RT system.
