摘要： A method and system for generating transmit pulses for use with an electrostatic transducer in harmonic imaging are provided. The excitation waveforms are pre-distorted to account for the non-linear output of the electrostatic transducer. Additionally, the force on a multiple element electrostatic transducer array is measured. A bias voltage is applied to the electrostatic transducer where the bias voltage is responsive to the measured force.

摘要： An medical diagnostic ultrasonic image processing method estimates motion between first and second composite ultrasonic images that include both B-mode and Color Doppler information. First and second B-mode images are extracted from the first and second composite ultrasonic images, respectively, and then motion is estimated between the first and second B-mode images. The estimated motion is then used to compose a multi-frame image using at least portions of the composite ultrasonic images or derivatives of the composite ultrasonic images, such as the B-mode images.

摘要： Ultrasound data is generated by a receive beamformer. Ultrasound image processing is applied to the ultrasound data for presentation of an image. Various ones of the ultrasound image processing steps may be reversed. For example, persistence processing may be reversed in order to obtain ultrasound data associated with data prior to persistence processing. This recovered data may be used to generate an image or for application of a different amount of persistence. Other processes that may be reversed to recover ultrasound data include focal and depth gain compensation, dynamic range compression, intensity or color mapping, and various filtering, such as persistence or spatial filtering.

摘要： A method for imaging a target includes the steps of transmitting ultrasonic energy at a fundamental frequency and receiving reflected ultrasonic energy at a harmonic of the fundamental frequency. The ultrasonic energy is transmitted in power bursts, each having a respective envelope shape, wherein the envelope shapes rise gradually to a respective maximum value and fall gradually from the respective maximum value. Ultrasonic energy in the transmit beam is focused in an elongated high power region, as for example by means of a line focus.

摘要： A method for measuring Doppler ultrasound information transmits a transmit beam having a frequency dependent focus in which low-frequency components of the transmit beam are focused at long ranges and progressively higher frequency components of the transmit beam are focused at progressively shorter ranges. Beamformed receive signals are generated in response to receive signals from the transducers, and these beamformed receive signals are applied to Doppler processors. The frequency dependent focus of the transmit beam provides a transmit beam that is more uniform in width and intensity, and the Doppler processors thereby provide an improved Doppler image signal.
