摘要： Method and system for ultrasound imaging of body tissue in which a focused ultrasound (FUS) transducer (20) is oriented relative to the body such that ultrasonic waves generated by the FUS transducer (20) are directed toward the tissue being imaged. The FUS transducer (20) is operated to cause the formation of microbubbles (28) in the tissue and an ultrasound image of the tissue with the microbubbles (28) is acquired. Phase aberration in the acquired ultrasound image may be corrected, if necessary, using each microbubble (28) as a point source or point-like scatterer. Microbubble (28) formation can therefore be obtained in a non-invasive manner since FUS-induced microbubble (28) formation does not require the insertion of interventional tools into the body.

摘要： An invasive medical device includes a fluid path of microbubbles which is imaged by ultrasound during use of the device. The fluid path extends through the device, preferably to the distal end of the device, so that the diffuse reflection of ultrasound from the microbubbles can be received to image the location of the device. The fluid path can be open, terminating at the tip of the device, or can be a closed path of a circulating microbubble fluid used for imaging and/or cooling.

摘要： The present invention relates to monitoring the focus of a therapeutic transducer in an interactive real-time manner by turning off the ultrasound transmits of the imaging transducer but continuing to receive in all directions with an imaging probe in order to identify the therapeutic beam focus. The therapeutic focused beam acts as the only transmit and as long as there is a scatterer at the focus, a strong receive signal will be generated to identify the focus.

摘要： The present disclosure provides for effective systems and methods for increasing target tissue conspicuity within a particular anatomy of a particular patient. In an exemplary embodiment, a system associated with the present disclosure includes: (a) a MRI-guided HIFU system for generating ablation markings on a target tissue region, the MRI-guided HIFU system including a transducer for delivering HIFU to the target tissue region, the delivered HIFU generating the ablation markings on the target tissue and an MRI imaging system adapted to generate a three dimensional image of the target tissue region during HIFU delivery for guiding the delivery of the HIFU to the target tissue region; (b) a radiotherapy delivery system for delivering radiotherapy treatment to the target tissue region; and (c) a CT imaging system operable within the radiotherapy delivery system for generating a three dimensional image of the target tissue region. The markings generated on the target tissue region by the MRI-guided HIFU are visible in the image generated by the CT imaging system. The image generated by the CT imaging system guides the location of the radiotherapy treatment delivered to the target tissue region.

摘要： A therapy system comprises a therapy module to direct a therapeutic action to a target along successive trajectories in a target zone that includes the target. A thermometry module is provided to measure temperature in a measurement field and to compute a thermal dose. The measurement field at least partially covers the target zone. A control module controls the therapy module to switch the therapeutic action to a next successive trajectory on the basis of the measured temperature or thermal dose. The successive trajectories are located inside of or outside of one another within the target zone. The therapeutic action comprises application of a focused ultrasound beam to the target. Temperature measurement is done on the basis of magnetic resonance signals.
