Filed:

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.

International Classification:

G03B 4206

US Classification:

367 7

Abstract:

A multi-dimensional beamforming device that performs consecutive one-dimensional operations. For example, beamsteering for a two-dimensional array can be include a projection of a beam onto each of the respective axes of the array. In such a device, a first beamforming processing element is used to form multiple beams for each array output along a given row. In a preferred embodiment, sequential output vectors from the first processing element are then applied to a transposing or corner turning memory and the data are reformatted such that all elements on a given column of the array are applied to a second beam forming processing element.

US Classification:

600424

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.

Assignee:

TeraTech Corporation - Burlington MA

International Classification:

A61B 800

US Classification:

12866101

Abstract:

A portable ultrasound imaging system includes a hand-held scan head coupled by a cable to a portable battery-powered data processor and display unit, preferably in the form of a lap-top computer. The scan head enclosure houses an array of ultrasonic transducers and the circuitry associated therewith, including pulse synchronizer circuitry used in the transmit mode to time 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. Because the pulse synchronizer and beam forming circuits are integrated on small chips, they can be included in the scan head, resulting in a portable low-power system. Also, since the beam forming and summation functions are performed in the scan head in proximity to the transducer elements, signal loss is substantially reduced, resulting in much higher image quality. In addition, the focused summed signal is transferred to the data processor and display unit by a cable which is far less sophisticated and expensive than the cables used in prior systems to transfer all of the transducer signals to a console signal processing unit.

Inventors:

Alice M. Chiang - Weston MA

Assignee:

Massachusetts Institute of Technology - Cambridge MA

International Classification:

G06F 15332

US Classification:

364725

Abstract:

A three dimensional (3D) discrete cosine transform (DCT) uses one dimensional DCT networks for transforming and inverse-transforming blocks of data, such as image data. The 3D DCT configuration uses DCT transform coding to remove both the spatial and temporal redundancy of a sequence of image frames to achieve high bandwidth compression.
