A method is provided for making a backing layer for an ultrasonic matrix array transducer useful in medical imaging and the like. A conductive grid is provided which includes a plurality of micro-contacts each joined together by a common base so that spaces are provided between the free ends ...
A transducer originally designed for transesophageal echocardiography (TEE) was adapted for real-time volumetric endoscopic imaging of the brain. The transducer consists of a 36 × 36 array with an interelement spacing of 0.18 mm. There are 504 transmitting and 252 receive channels placed in a reg...
This matrix-array transducer can generate both a narrow calibration beam and a broad spectral Doppler measurement beam using electronic beamwidth control over both the lateral and elevational apertures. Ultimately, the two beams need to be generated simultaneouslyto make calibration and measurement a one...

With these multiple rows of crystals (64 rows in some), the transducer footprint has more than 8,000 elements, hence the name “matrix array transducers”. In conventional mechanical 3D probes, a single row of crystals is used to generate the 2D image and once the 3D acquisition is ...
The array concept features separated transmit and receive subarrays. The element geometry was studied using finite element modeling and a transmit subarray prototype was examined both acoustically and with laser interferometry. The transmit subarray is suitable for its role, with a 3 MHz resonance ...
