    摘要: A medical diagnostic ultrasound imaging system is responsive to a user position. A sensor determines the position of the user. One or more components of the ultrasound imaging system move as a function of the sensed position. For example, the display and/or control panel of the ultrasound imaging system rotate or translate based on motion or a current position of the user. As the user leans or moves during an examination, at least a component of the ultrasound system compensates for the change in position. As another example, the ultrasound imaging system follows the user from one patient to another patient. As another example, the ultrasound imaging system packages itself. The user may move for purposes other than adjusting a position of the ultrasound imaging system or a component thereof, but the system or component moves to aid the user.

    摘要: Automated analysis of ultrasound data is provided to extract event times, such as valve opening and closing times. Different types of ultrasound data, such as B-mode, M-mode, tissue velocity or flow velocity, are processed by a processor to identify automatically the event times. The event times are used for the processing of ultrasound data or to assist diagnosis. The event times may be used to estimate other event times in different heart cycles, such as with interpolation or extrapolation.

    摘要: The phase or associated amplitude analysis of a sequence of images is improved by, first, providing quantifications in response to the phase or amplitude information. For example, a value or values representing asynchrony between different locations through a sequence of images may provide useful diagnostic information. Second, since heart motion or other motion within a body may become complex, multiple harmonics may be used in addition to the first harmonic or fundamental information for parametrically imaging a motion. Third, where different portions of a cycle have different characteristics, such as the systolic phase and diastolic phase of a heart cycle, images associated with each of the portions may be separated from other portions. A phase or amplitude analysis of the sequence of images for each portion is handled separately.

    摘要: Dynamic steered spatial compounding is provided in ultrasound imaging. The compounding adjusts for variance. The compounding dynamically reacts to variance due to motion and/or view direction. For each location, the weights are set based on the motion or signal variance for the respective location. The weighting used for compounding or the results of the compounding adapt to maintain or increase signal fidelity.

    摘要: A system and method of detecting acousto-photonic emissions in optically turbid media that provide increased levels of detection sensitivity. The detection system includes an ultrasonic transducer, a laser, a photo-detector for detecting ultrasound-modulated laser light, and circuitry for processing the detected signals for subsequent analysis. The ultrasonic transducer generates an ultrasonic wave that propagates within an optically turbid medium. The laser generates a coherent light beam, which is split to form signal and reference beams. The signal beam is sent through the turbid medium, where it is phase modulated by the ultrasound. The ultrasound-modulated signal beam is provided to a photo-refractive crystal for subsequent interference with the reference beam to convert the phase modulation to intensity modulation. The DC offset of the signal beam intensity provides a measure of the magnitude of the mean phase shift induced by the ultrasound on the multiply scattered optical field within the turbid medium.

    摘要: A multimode flow meter can use both the time-of-transit of upstream and downstream ultrasonic signals and time for transmission of downstream-only signals to determine a flow velocity of a medium flowing through a conduit. Based on factors, such as previously computed flow velocity and signal-to-noise ratio of the upstream signal, a mode of operation may be switched and only the time for transmission of the downstream signals may be used to determine flow velocity. The multimode flow meter can compute cross-flow to reduce its effect on the determination of flow velocity.

    摘要: Frequency variation is used in frequency compounding. A phase inversion harmonic image is compounded with a downshift harmonic image. The depths for downshifting fractional harmonics are determined based on a signal-to-noise ratio of the harmonic information at a given harmonic. The depth for transition between one type of harmonic imaging (e.g., phase inversion) and another (e.g., downshifted harmonic) is determined based on a similarity of the one type with noise. Weights used for frequency compounding are determined based on a difference between noise and one of the types of data to be compounded, and spatially steering angles.
