20090016163 | LINEAR ARRAY ULTRASOUND TRANSDUCER WITH MICROBEAMFORMER - An ultrasonic diagnostic imaging system has a two dimensional array arranged in multiple patches of multiple transducer elements. Each patch of transducer elements is coupled to a group of microbeamformer delay lines having outputs coupled to a channel of a system beamformer, which beamforms the partially summed beams of each patch into a final beamformed signal. The outputs from multiple patches which are not simultaneously used in the active receive aperture are coupled to a common beamformer channel, enabling the number of patches of the array to exceed the number of channels of the system beamformer without the use of multiplexers. | 01-15-2009 |
20090171213 | LINEAR ARRAY ULTRASOUND TRANSDUCER WITH VARIABLE PATCH BOUNDARIES - An ultrasonic diagnostic imaging system has a two dimensional array arranged in multiple patches of multiple transducer elements. Each patch of transducer elements is coupled to a group of microbeamformer delay lines having outputs which can be coupled to a selected channel of a system beamformer, which beamforms the partially summed beams of each patch into a final beamformed signal. The ability to direct a delayed signal from a transducer element to a selected beamformer channel enables the patch boundaries to be changed as the aperture is translated across the array. | 07-02-2009 |
20090203996 | ULTRASOUND-IMAGING SYSTEMS AND METHODS FOR A USER-GUIDED THREE-DIMENSIONAL VOLUME-SCAN SEQUENCE - An ultrasound-imaging system and method is provided that permits an operator to acquire an image of a volume-of-interest in a time critical fashion, that is capable of referencing the volume rendering to a standard two-dimensional imaging mode, and permits the operator to selectively choose a number of display-mode parameters that result in an operator directed view of the volume-of-interest. The ultrasound-imaging system comprises an input device configured to receive a plurality of imaging parameters and a controller in communication with the input device. The ultrasound-imaging system generates an operator-directed transmit-beam scan sequence in response to the imaging parameters and transmits a spatially modified transmit-beam scan sequence over a portion of the volume-scan range of the ultrasound-imaging system. Moreover, the ultrasound-imaging system provides the flexibility for an operator to direct a plurality of operator-configurable multi-dimensional views. | 08-13-2009 |

20140058270 | MATRIX ULTRASOUND PROBE WITH PASSIVE HEAT DISSIPATION - A matrix array ultrasound probe passively dissipates heat developed by the matrix array transducer and beamformer ASIC away from the distal end of the probe. The heat developed in the transducer stack is coupled to a metallic frame inside the handle of probe. A metallic heatspreader is thermally coupled to the probe frame to convey heat away from the frame. The heatspreader surrounds the inside of the probe handle and has an outer surface which is thermally coupled to the inner surface of the probe housing. Heat is thereby coupled evenly from the heatspreader into the housing without the development of hotspots in the housing which could be uncomfortable to the hand of the sonographer. | 02-27-2014 |
20150085617 | ULTRASOUND TRANSDUCER ARRAYS WITH VARIABLE PATCH GEOMETRIES - A two dimensional ultrasonic array transducer receives echo signals from increasing depths of a volumetric region. The 2D array is configured into patches of elements which are processed by a microbeamformer and summed signals from a patch are coupled to a channel of an ultrasound beamformer At the shallowest depth the 2D array receives echoes from small patches in the center of the aperture. As signals are received from increasing depths the aperture is grown by symmetrically adding patches of progressively larger sizes on either side of the small patches in the center. The inventive technique can improve the multiline performance of both 1D and 2D array probes. | 03-26-2015 |

20150241397 | TWO DIMENSIONAL ULTRASOUND TRANSDUCER ARRAYS OPERABLE WITH DIFFERENT ULTRASOUND SYSTEMS - A matrix array transducer probe has a two dimensional array of transducer elements coupled to adjustable delays for each element. A controllable switch matrix combines a plurality of differently delayed element signals to form a patch signal and produces a plurality of patch signals in this manner. The switch matrix determines the patch configuration in consideration of the number of channels of a system beamformer which completes the beamformation, and the element delays are set in consideration of the configuration of the elements to be used in each patch. Patch signal formation may be done in two stages, including a stage which includes a hard-wired signal combiner. The matrix array probe can be operated with differently sized system beamformers or the same transducer stack used in different probes configured for specific beamformer configurations. | 08-27-2015 |
