Abstract
A method and system are disclosed for radiosurgical treatment of moving tissues of the heart, including acquiring at least one volume of the tissue and acquiring at least one ultrasound data set, image or volume of the tissue using an ultrasound transducer disposed at a position. A similarity measure is computed between the ultrasound image or volume and the acquired volume or a simulated ultrasound data set, image or volume. A robot is configured in response to the similarity measure and the position of the transducer, and a radiation beam is fired from the configured robot.
Claims9
An ultrasound tissue imaging system comprising:
- an ultrasound image sensor to generate ultrasound data of a target included within or adjacent to an anatomical site;
- an input for receiving other image data regarding the anatomical site from another imaging modality;
- a processor configured to generate ultrasound image correction data of the anatomical site from the other image data to compensate for distortion of the ultrasound data;
- and
- an image or measurement output coupled to the processor for communication of an ultrasound measurement or image of the target in response to the correction data.
