Abstract: An ultrasound system for an ultrasound therapy (ablation or hyperthermia) of a region of interest comprising: a patch comprising a two-dimensional array of ultrasonic transducers (preferably CMUTs) arranged on a support, wherein a plurality of the transducers is adapted to operate in a variable frequency range; a transducer controller means adopted to activate at least two groups of the plurality of the transducers in the array for a transmission of the ultrasound signals, wherein each of the at least two groups: is arranged in a pattern; and operates at a frequency different from other group's frequency.

Abstract: The invention relates to a system for assisting a user in positioning a thermal ablation device (1) on the basis of a planned ablation position. The system comprises an evaluation unit (6) adapted to (i) compute an optimized thermal dose distribution deliverable to the treatment region by means of the device (1) operating at a current position thereof, (ii) determine a path for steering the device (1) from the current position to the planned position and to assign a cost to the determined path, the cost quantifying estimated detrimental effects of steering the device (1) along the computed path, and (iii) present information about the optimized thermal dose distribution and about the cost assigned to the computed path to the user.

Abstract: The invention relates to a therapy planning device for planning a therapy to be applied to tissue of a subject (2). A tissue parameter distribution, which has been generated based on a magnetic resonance fingerprint scan of the tissue, and a therapy goal distribution, which defines a distribution of at least one parameter being indicative of a desired effect of the therapy, are provided. A machine learning module (13), which has been trained to output at least one therapy application parameter defining the application of the therapy based on an input tissue parameter distribution and an input therapy goal distribution, is used for planning the therapy by determining the at least one therapy application parameter based on the provided tissue parameter distribution and the provided therapy goal distribution. This allows for a consideration of the actual quantitative tissue parameter distribution of the patient, thereby improving planning quality.

Abstract: An ultrasound probe positioning system (100) comprises a positioning unit (102) for holding an ultrasound probe unit (104) and for moving the ultrasound probe unit and positioning it at a target position and a positioning control unit (106) configured to provide target positioning data indicative of a target position that establishes a mechanical contact of the ultrasound probe unit with an external object (110) and to control the mechanical positioning unit in moving and positioning the ultrasound probe at the target position. The positioning unit comprises a force actuation unit (108) configured to adapt a pressing force amount of a mechanical pressing force exerted on the object in response to a variation of a counterforce amount so as to maintain a predetermined net pressing force amount exerted by the mechanical pressing force against the counterforce.
