Abstract: A device for ultrasound tests, includes one or more transducers for generating ultrasound beams with different powers/frequencies to be projected in direction of multiple targets, to ensure separate control of the temperature both of the targets and of the transducers and allows performing several tests contemporarily, by optimizing the functionality and the efficiency of the device, and guaranteeing results comparable therebetween for each test.

Abstract: The invention relates to an ultrasonic transmitter arrangement (1) with a plurality of ultrasonic transmitters (2) arranged on the arrangement whose emittable ultrasonic waves are focused toward a common focus (3). The arrangement (1) is embodied as a cranial bone implant (4) that can be implanted in the cranial bones (5) of a person as a replacement for one or more parts of the cranial bone (5), with the common focus (3) of the entire arrangement being arranged in a defined region of the brain (6) in the implanted state.

Abstract: A phased-network ultrasound transducer for medical use, includes a single support (2) and a group of transducer elements (3) distributed randomly on the surface of the support (2), the transducer elements (3) being fixed. The group includes at least two sub-groups of transducer elements (3), each of the sub-groups having a different geometric point of convergence such as to focus an ultrasound energy in a different coverage volume (4, 5) such that the arrangement of the coverage volumes covers a target volume to be treated. In addition, the transducer includes control elements for controlling the transducer elements (3) independently of one another.

Abstract: The inventive device for treating a biological tissue volume by a localised hyperthermy comprises a plurality of active percutaneous electrodes (1-N), at least one return electrode (120) and a high-frequency (100) electric generator for applying an alternating voltage between said active electrodes and return electrode.
