Abstract
A method of damaging a target tissue of a subject is disclosed. The method comprises: (a) imaging a region containing the target tissue; (b) determining a focal region of a damaging radiation; (c) positioning the focal region onto the target tissue; and (d) damaging the target tissue by an effective amount of the damaging radiation. The determination of the focal region is by delivering to the region bursts of ultrasonic radiation from a plurality of directions and at a plurality of different frequencies, and passively scanning the region so as to receive from the region ultrasonic radiation having at least one frequency other than the plurality of different frequencies.
Claims78
A method of determining a focal region of high intensity focused ultrasound (HIFU), the method comprising delivering to a region bursts of the HIFU from a plurality of directions and at a plurality of different frequencies, and passively scanning the region so as to receive from said region ultrasonic radiation having at least one frequency other than said plurality of different frequencies, thereby determining the focal region of the HIFU.
A method of damaging a target tissue of a subject by high intensity focused ultrasound (HIFU), the method comprising:
- (a) imaging a region containing the target tissue, using an imaging system;
- (b) determining a focal region of the HIFU;
- (c) positioning said focal region onto the target tissue;
- and
- (d) damaging the target tissue by an effective amount of the HIFU;
- wherein said determination of said focal region is by delivering to said region bursts of the HIFU from a plurality of directions and at a plurality of different frequencies, and passively scanning the region so as to receive from said region ultrasonic radiation having at least one frequency other than said plurality of different frequencies.
A method of damaging a target tissue of a subject, the method comprising imaging a region containing the target tissue by transmission ultrasound computerized tomography (TUCT) and damaging the target tissue by an effective amount of damaging radiation.
A method of imaging a region containing an internal target tissue of a subject, comprising:
- inserting an intracorporeal ultrasound device to the subject;
- positioning an extracorporeal ultrasound device opposite to said intracorporeal ultrasound device, such that at least a portion of the region is interposed between said intracorporeal ultrasound device and said extracorporeal ultrasound device;
- using said intracorporeal ultrasound device and said extracorporeal ultrasound device to transmit ultrasonic radiation through the region;
- scanning the region using at least one of said intracorporeal ultrasound device and said extracorporeal ultrasound device;
- and
- analyzing said ultrasonic radiation so as to generate an image of the region by transmission ultrasound computerized tomography (TUCT).
A high intensity focused ultrasound (HIFU) system, comprising:
- a HIFU device, capable of transmitting the HIFU from a plurality of directions and at a plurality of different frequencies, and receiving ultrasonic radiation having at least one frequency other than said plurality of different frequencies;
- and
- a data processor, designed and constructed to determine a focal region of said HIFU based on said at least one frequency other than said plurality of different frequencies.
A system for damaging a target tissue, comprising:
- (a) an imaging system, for imaging a region containing the target tissue;
- (b) a high intensity focused ultrasound (HIFU) device, capable of transmitting the HIFU from a plurality of directions and at a plurality of different frequencies, and receiving ultrasonic radiation having at least one frequency other than said plurality of different frequencies;
- and
- (c) a data processor, designed and constructed to determine a focal region of said HIFU based on said at least one frequency other than said plurality of different frequencies.
A system for damaging a target tissue, comprising:
- (a) a transmission ultrasound computerized tomography (TUCT) system, for imaging a region containing the target tissue by TUCT;
- and
- (b) a radiation system for transmitting to the target tissue an effective amount of damaging radiation to thereby cause damage to the target tissue.
A system for transmission ultrasound computerized tomography (TUCT), the system comprising an intracorporeal ultrasound device, an extracorporeal ultrasound device, and a data processor for analyzing ultrasonic radiation transmitted between said intracorporeal ultrasound device and said extracorporeal ultrasound device so as to generate an image of the region by TUCT.
