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.

An ultrasound treatment comprises applying ultrasound at a first energy level () to a region of interest () in a subject for activating a cavitation nucleation agent during a first portion of a treatment cycle (t-t). Ultrasound at a second energy level () is applied to the region of interest () during a second portion of the treatment cycle (t-t) for implementing a desired thermal therapy in the presence of the cavitation nucleation agent activated during the first portion of the treatment cycle. The second energy level is at an energy level different from the first energy level.

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

System and method for enabling intra-operative selection of an image registration transformation for use in displaying a first image dataset and a second image dataset in correspondence with one another. Image dataset acquisition devices () obtain the first and second image datasets. A similarity function indicative of a likelihood that the first and second image datasets are in correspondence with one another is computed by a processor () and then a ranking of each of a plurality of local maxima of the similarity function is determined. Registration transformations derived from a plurality of the local maxima are displayed on a display (), and using a user-interface (), a physician can select each registration transformation to ascertain visually whether it is the clinically-optimal registration transformation for subsequent use.

A therapy system comprises a therapy module to direct a therapeutic action to a target along successive trajectories in a target region that includes the target. A thermometry module is provided to measure temperature a measurement field and in particular to compute a thermal dose. A control module to controls the therapy module to apply the therapeutic action along the respective trajectories on the basis of the measured temperature and/or thermal dose. The successive trajectories are located in the target zone outward or inward relative to one another within the target zone. In particular the therapeutic action subsists in application a focused ultrasound beam to the target. Temperature measurement is done on the basis of magnetic resonance signals.

A therapy system comprises a therapy module to perform successive deposits of energy in a target zone, the therapy system being provided with a control module is configured to prior the deposits of energy produce an a priori estimate of the induced heating. For example a thermometry module is provided to measure temperature in a measurement field. The induced heating may be derived on the basis of a tissue model from the settings of the therapy module. In particular the therapy module is a high-intensity focuses ultrasound transmitter. A magnetic resonance examination system configured for thermometry is employed as the thermometry module.
