摘要： Transducer assembly transmits ultrasonic energy towards a zone acoustically coupled to an object or area of interest, and comprises a piezoelectric subassembly matching a curved support layer disposed behind said subassembly. Piezoelectric subassembly comprises piezoelectric elements and metal connections. Piezoelectric elements are disposed along a first azimuth direction to form parallel curved segments of piezoelectric elements extending in a second elevation direction, each being in contact with a corresponding metal connection extending in the elevation direction for transmitting/receiving electric signals to/from each piezoelectric segment. The subassembly has a central part comprising piezoelectric material and a lateral part comprising resin material incorporating the metal connections so that each curved segment results in a sequence of resin/piezoelectric/resin materials disposed along the elevation direction with the extension and curvature of the piezoelectric material in the central part defining the elevation focusing of the transducer assembly. A corresponding manufacturing process is also disclosed.

摘要： A tracker-less method is provided for registering images acquired with different modalities for generating fusion images from registered images acquired with different modalities. The method acquires a sequence of ultrasound images by interlacing wide, high depth ultrasound scans to zoomed ultrasound scans; and registers image data obtained from the high-depth ultrasound scans with image data of the same anatomical region acquired with a different modality and determining registration data. The image data obtained from the high-depth ultrasound scan and/or the image data acquired with the different modality is not displayed to the user. Image data acquired by the zoomed ultrasound scan is registered with the zoomed image data obtained with the different modality by applying the registration data to the image data acquired by the zoomed ultrasound scans. Registered image data is combined with the zoomed image data obtained with the different modality and the combined or image data is displayed.

摘要： A method for automatically detecting of the probe which is selected for the use by the user without manual commands by the user and comprising monitoring the operational status of the probe by discriminating between probe not in use and probe in use by sensing at least the motion of the probe and by setting automatically a probe in an active status if a motion of the probe is sensed and setting the probe in an inactive status if the probe is stationary.

摘要： In a dematerialized ultrasound system, i.e. comprising a probe for transmitting and receiving ultrasound signals and a generic processing hardware made of one or more distributed processing units, the functions relating to the processing steps for the generation and processing of the images are in the form of software programs that encode instructions for the aforementioned generic hardware which make it capable of executing said processing steps. In order to make the computational and data interchange burden less heavy between the units of the distributed architecture of the system and to make the distribution of processing steps more flexible between one or more of the components of the distributed system, the programs are created under form of applications included in containers managed by a container management engine.
