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.
Claims43
A method for treating a moving tissue, the method comprising:
- acquiring at least one volume of the tissue;
- acquiring at least one ultrasound data set, image or volume of the tissue using an ultrasound transducer disposed at a position;
- computing a similarity measure between:
- the ultrasound data set, image or volume and
- the acquired volume or a simulated ultrasound data set, image or volume therefrom;
- configuring a robot in response to the similarity measure and the position of the transducer;
- and
- firing a radiation beam from the configured robot.
A method for treating a heart, the method comprising:
- acquiring at least one volume of the heart;
- acquiring at least one ultrasound data set of the heart using a transducer;
- simulating an ultrasound data set from the volume;
- computing a similarity measure between the ultrasound data set and the simulated ultrasound data set;
- configuring a robot dependent on the similarity measure;
- and
- firing a radiation beam dependent on the configuration of the robot.
A method for treating a target on a moving heart, the method comprising:
- acquiring at least one volume of the target;
- acquiring at least one ultrasound volume of the target using a volumetric transducer;
- computing a similarity measure between the ultrasound volume and the volume;
- configuring a 6 DOF robot dependent on the similarity measure and on a position of the transducer;
- and
- firing a radiation beam at the target dependent on the configuration of the robot.
A system for treating a moving tissue, the system comprising:
- a volume acquisition system for acquiring at least one volume of the tissue;
- a transducer with a position sensor for acquiring at least one ultrasound data set, image or volume of the tissue and associated position information;
- a processor coupled to the acquisition system and the transducer, the processor configured for computing a similarity measure between:
- the ultrasound data set, image or volume and
- the acquired volume or a simulated ultrasound data set, image or volume therefrom;
- a robot coupled to the processor so as to be configured in response to the similarity measure and data and the associated position information;
- and
- a radiation source supported by the robot.
