Nov 23, 1999
Appl. No.:

09/447144
Inventors:

Jeffrey M. Gilbert - ElCerrito CA
Alice M. Chiang - Weston MA
Steven R. Broadstone - Woburn MA
Assignee:

TeraTech Corporation - Burlington MA
International Classification:

A61B 800
US Classification:

600447
Abstract:

An ultrasound imaging system includes a scan conversion process for converting ultrasound data into a standard display format conversion and can be performed on a personal computer by programming the computer to convert data from polar coordinates to cartesian coordinates suitable for display on a computer monitor. The data is provided from scan head enclosure that houses an array of ultrasonic transducers and the circuitry associated therewith, including pulse synchronizer circuitry used in the transmit mode for transmission of ultrasonic pulses and beam forming circuitry used in the receive mode to dynamically focus reflected ultrasonic signals returning from the region of interest being imaged.

US Patent:

6552964, Apr 22, 2003
Filed:

Apr 6, 2001
Appl. No.:

09/828266
Inventors:

Alice M. Chiang - Weston MA
Steven R. Broadstone - Woburn MA
Assignee:

TeraTech Corporation - Burlington MA
International Classification:

H04B 102
US Classification:

367138
Abstract:

The need for multiple, cost-effective deployment of an underwater camera has resulted in the development of a low-power high-resolution imaging system using a sparse array. The system can be used for undersea acoustic mine-field reconnaissance and mine-hunting systems for example, this imaging sonar is portable enough for use in a divers hands or in a remote imaging sonar on an unmanned undersea vehicle in shallow waters. The present system can simultaneously focus many signals using multiple CCD/CMOS, programmable time-delay beamforming circuits connected to a sparsely-populated 2D acoustic array, is being developed. Using this approach, a real-time image can be formed to search for mine-like objects. To make a sparse array, the combination of low insertion loss and wide bandwidth performance is important for realizing acceptable imaging performance with low illumination levels.

US Patent:

6593880, Jul 15, 2003
Filed:

Nov 9, 1998
Appl. No.:

09/188835
Inventors:

Scott R. Velazquez - Revere MA
Steven R. Broadstone - Woburn MA
Alice M. Chiang - Weston MA
Assignee:

TeraTech Corporation - Burlington MA
International Classification:

H04B 700
US Classification:

342367, 3423571, 342383
Abstract:

A wireless communication system employs directive antenna arrays and knowledge of position of users to form narrow antenna beams to and from desired users and away from undesired users to reduce co-channel interference. By reducing co-channel interference coming from different directions, spatial filtering with antenna arrays improves the call capacity of the system. A space division multiple access (SDMA) system allocates a narrow antenna beam pattern to each user in the system so that each user has its own communication channel free from co-channel interference. The position of the users is determined using geo-location techniques. Geo-location can be derived via triangulation between cellular base stations or via a global positioning system (GPS) receiver. The system can be optimized by applying partially adaptive processing algorithms, which are seeded by geo-location data.

Appl. No.:

09/966810
Inventors:

Xingbai He - Waltham MA
Peter P. Chang - Arlington MA
Eric R. Kischell - Pepperell MA
Alice M. Chiang - Weston MA
Assignee:

TeraTech Corporation - Burlington MA
International Classification:

A61B 800
US Classification:

600443, 600447
Abstract:

The present invention is directed to an ultrasound imaging system and method for Doppler processing of data. The ultrasonic imaging system efficiently addresses the data computational and processing needs of Doppler processing. Software executable sequences in accordance with a preferred embodiment of the present invention determines the phase shift and the auto-correlation phase of filtered image data. In a preferred embodiment, the system of ultrasonic imaging also includes a sequence of instructions for Doppler processing that provides the functions for demodulation, Gauss Match filtering, auto-correlation calculation, phase shift calculation, frame averaging, and scan conversion implemented with Single Instruction Multiple Data (SIMD) or Multiple Instruction Multiple Data (MIMD) instructions. In a preferred embodiment, the ultrasound imaging system of the present invention includes a processing module; and memory operable coupled to the processing module, wherein the memory stores operational instructions that cause the processing module to map serial data to vector representation, calculate an auto-correlation function of the data, calculate a phase shift of the auto-correlation function to generate a monotonic function covering all values of the phase shift corresponding to a range of Doppler velocities and display the resultant images, for example, as color images.

Filed:

Feb 22, 2001
Appl. No.:

09/791491
Inventors:

Alice M. Chiang - Weston MA
Michael P. Litchfield - Winchester MA
Michael Brodsky - Brookline MA
Eric R. Kischell - Pepperell MA
Assignee:

TeraTech Corporation - Burlington MA
International Classification:

A61B 800
US Classification:

600437
Abstract:

A hand-held ultrasound system includes integrated electronics within an ergonomic housing. The electronics includes control circuitry, beamforming and circuitry transducer drive circuitry. The electronics communicate with a host computer using an industry standard high speed serial bus. The ultrasonic imaging system is operable on a standard, commercially available, user computing device without specific hardware modifications, and is adapted to interface with an external application without modification to the ultrasonic imaging system to allow a user to gather ultrasonic data on a standard user computing device such as a PC, and employ the data so gathered via an independent external application without requiring a custom system, expensive hardware modifications, or system rebuilds. An integrated interface program allows such ultrasonic data to be invoked by a variety of such external applications having access to the integrated interface program via a standard, predetermined platform such as visual basic or c++.

US Patent:

6842401, Jan 11, 2005
Filed:

Jul 19, 2001
Appl. No.:

09/909141
Inventors:

Alice M. Chiang - Weston MA, US
Steven R. Broadstone - Woburn MA, US
Assignee:

TeraTech Corporation - Burlington MA
International Classification:

H04B 102
US Classification:

367138
Abstract:

The present invention relates to sonar beamforming systems and methods, using a forward-looking sonar having transmit and receive transducer arrays with a beamforming device and at least one side-looking sonar having dynamically range-focused beams. The forward-looking sonar provides for obstacle avoidance and undersea survey. The systems include one-dimensional transmit and receive transducer arrays with beamforming electronics, a computing controller such as, for example, a personal computer host controller. The arrays and beamforming electronics can be packaged in a hermetically sealed housing unit and mounted in Unmanned Underwater Vehicles (UUV). The side-looking sonar system includes for example, 32-element, one-dimensional arrays that are mounted on either side of the UUVs. Further, a downward looking Bathymetric sonar may be mounted on the underside of the vehicle for high-resolution mapping.
