    摘要： A system and method for real-time quantitative analysis of heart wall motion is provided. A Doppler imaging system is used to monitor the movement of a heart, or other organ. A B-mode reference image of the target organ is made and then a region-of-interest is defined through the use of a gate. Then pulsed wave spectral tissue Doppler data of the region-of-interest is formed and used to determine the velocity of a region of the target organ. The system may be used for determining appropriate biventricular pacemaker settings for patients suffering from heart disease.

    摘要： 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.

    摘要： A portable ultrasound imaging system includes a handheld 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.

    摘要： A full search block matching algorithm includes a charge-domain serial tapped delay line as an input buffer, and an array of charge domain signal processors. The delay line shifts and holds analog sampled data which are in the form of charge packets. At each stage of delay, the signals are nondestructively sensed and coupled to a corresponding signal processor, and the sampled data are transferred and subsequently processed in parallel. The processed data from all the processors can be read out either in a parallel or serial format through a parallel-in-serial-out output buffer. In this structure, only the serial input buffer has to be clocked at the system throughout rate; the internal clock rate of each processor is reduced by the number of parallel processors. Within each processor, all of the computation functions are performed in the charge domain, and local charge domain memories are included for storing the processed signal.
