摘要： An ultrasound probe capable of scanning an ultrasound beam in a region of 3D space, characterized by that an ultrasound transducer array is mounted to a 1st shaft that can rotate in bearings mounted in a fork that can be moved. The fork can be rotated around a 2nd shaft in a bearing, or moved through a sliding system, or a combination of the two. The shaft and the fork are connected to two separate electric motors for electric steering of the array direction within a region of 3D space. Position measurement systems are mounted to the shaft and the fork so that the beam direction can be steered with a feed-back control system.

摘要： Elastic wave pulse complexes are transmitted towards said region where said pulse complexes are composed of a high frequency (HF) and a low frequency (LF) pulse with the same or overlapping beam directions and where the HF pulse is so close to the LF pulse that it observes the modification of the object by the LF pulse at least for a part of the image depth. Received HF signals are picked up by transducers from scattered and/or transmitted components of the transmitted HF pulses. The received HF signals are processed to form measurement or image signals for display, and combined in slow time to form noise suppressed HF signals or nonlinear scattering HF signals.

摘要： A design and a manufacturing method of ultrasound transducers based on films of ferro-electric ceramic material is presented, the transducers being particularly useful for operating at frequencies above 10 MHz. The manufacturing technique can involve tape-casting of the ceramic films, deposition of the ceramic films onto a substrate with thick film printing, sol-gel, or other deposition techniques, where manufacturing methods for load matching layers and composite ceramic layers are described. The designs also involve acoustic load matching layers that provide particularly wide bandwidth of the transducers, and also multi-band operation of the transducers. The basic designs can be used for elements in a transducer array, that provides the frequency characteristics of the single element transducers, for array steering of the focus and possibly also direction of a pulsed ultrasound beam at high frequencies and multi-band frequencies.

摘要： An ultrasound imaging probe for real time 3D ultrasound imaging from the tip of the probe that can be inserted into the body. The ultrasound beam is electronically scanned within a 2D azimuth plane with a linear array, and scanning in the elevation direction at right angle to the azimuth plane is obtained by mechanical movement of the array. The mechanical movement is either achieved by rotation of the array through a flexible wire, or through wobbling of the array, for example through hydraulic actuation. The probe can be made both flexible and stiff, where the flexible embodiment is particularly interesting for catheter imaging in the heart and vessels, and the stiff embodiment has applications in minimal invasive surgery and other procedures. The probe design allows for low cost manufacturing which allows factory sterilized probes to be disposed after use.

摘要： An ultrasound probe for three-dimensional scanning and focusing of an ultrasound beam in both an azimuth direction and an elevation direction normal to the azimuth direction. The probe is composed of an ultrasound transducer array which has a linear division of the elements in the azimuth direction for electronic steering of the beam direction and focus in the azimuth direction. The array elements have a coarse division in the elevation direction for electronic steering of the focus in the elevation direction, and possibly small angle direction steering of the beam in the elevation direction for parallel receive and/or transmit beams. Large angle direction scanning of the beam in the elevation direction is obtained by mechanical rotation of the array around an axis. The invention implies useful embodiments for insertion of the probe into the body, through mounting the array at the distal tip of an elongated device.
