摘要： An ultrasound imaging system may use a capacitive membrane or electrostrictive ultrasound transducer to realize isotropic volumetric imaging with bias-line element selection and a variety of aperture synthesis techniques. Two dimensional beam formation may be performed by using a beamformer to focus along one dimension, and then perform a second round of “off-line” or “retrospective” beam formation along the other direction.

摘要： Synthetic transmit aperture is provided for three-dimensional ultrasound imaging. A transducer may have separate transmit and receive elements. Broad beams are transmitted, allowing fewer transmit elements and/or more rapid scanning. A multidimensional receive array generates data in response to sequential transmissions, such as transmissions from different angles. The data is combined to increase resolution. A transducer array with offset transmit elements for forming a transmit line source may be used.

The switches are implemented with one or more transistors. The control causes the gates of the transistor to float during the “on” connection. While on, the switch connects, allowing ultrasound signals to pass through the switch.

摘要： Medical diagnostic ultrasound imaging is performed with a multi-dimensional transducer array and an imaging system for planar scanning. The elements of the array may be distributed on a periodic grid with aperiodic shifts in position. When a one-dimensional array is formed on the array, the aperiodic shifts better distribute acoustic energies, reducing peaks in side lobes. Using a layered structure of switches underneath the acoustic elements, side lobes may be further reduced. The switches are used for interconnecting elements to form macro elements of the one-dimensional aperture on the multi-dimensional array. The switches are distributed on a grid corresponding to the desired imaging frequency. The acoustic elements are distributed with a finer pitch. The finer pitch allows formation of the macro elements for the one-dimensional aperture where the edges of the macro elements have fewer or no periodic patterns.

摘要： A single chip transducer apparatus that includes on-chip electronic circuitry which, when connected properly to a two-dimensional matrix of ultrasonic transducer elements, provides enough information to an external imaging system to form three-dimensional images of the subject of interest. In a preferred embodiment, the circuitry provides an amplifier for each transducer element, and then conditions the output of the amplifier in several ways. In one embodiment of the invention, the elements' analog voltages are stored in a sample and hold circuit, and time multiplexed into a high speed line driver that sends many elements data down the interconnect to the system's high speed Analog to Digital converters. In another embodiment, the gain of the amplifiers can be controlled in time to provide aperture translation and time based expansion for translating and focusing image slices in the elevation direction.
