摘要： Velocity scale is automatically determined for ultrasound imaging. Receive signals corresponding to different pulse repetition intervals are used to estimate velocities. The different velocities are used to determine the velocity scale. For example, the different pulse repetition intervals are obtained by selecting different sets of signals from a group of signals for a scan line. As another example, the different pulse repetition intervals are obtained by transmitting for a scan line with changing, such as increasing, pulse repetition intervals. The lower pulse repetition interval of a pair of intervals associated with a sign change in the phase is used for the velocity scale. In yet another example, at least two demodulation frequencies are used for a broadband transmit in at least two sets, each set with a different pulse repetition interval. Velocities are estimated for a greater number of pulse repetition intervals than transmitted using the broadband pulses.

摘要： Ultrasound transducer temperatures are measured in response to a temperature dependent property of the ultrasound transducer. The temperature is measured without addition of new electronics or hardware retrofits of the transducer. By implementing software and/or hardware on the ultrasound system rather than the transducer, the temperature is measured in order to provide a level of fault protection. The upgraded or new ultrasound system uses either old or new transducers while still providing temperature measurement. For example, the temperature of the lens or window is measured as a function of changes in attenuation or acoustic velocity. The receive beamformer already implemented on many ultrasound systems is used to measure a temperature dependent property of the lens or window. As another example, the dielectric constant or capacitance of one or more transducer elements is measured using additional hardware in the ultrasound system. The signal line and associated cable for one or more piezoelectric elements is switchably connected between hardware for measuring a capacitance and the receive beamformer for imaging. Rather than temperature, the operational state of the transducer may be diagnosed using acoustic energy response of the lens.

摘要： An ultrasonic imaging system generates Doppler and B-mode image signals, and then uses a modulated, non-linear mapping function to combine the Doppler and B-mode image signals into an output signal. In another mode of operation the imaging system generates fundamental and harmonic frequency intensity values and maps these intensity values to display indicia, preferably with a modulated, non-linear mapping function.

摘要： Color Doppler data is acquired only over a portion of the cardiac cycle, such as during diastole in order to increase the sensitivity of detection. Ultrasound system parameters such as clutter filter coefficience, temporal and spatial filter coefficients and demodulation frequencies may be altered only for a portion of the cardiac cycle to increase detection sensitivity, to improve myocardial border estimation and to avoid the loss of color Doppler image at end-diastole.

摘要： An ultrasound imaging system generates a legend on a display device. This legend includes at least two axes and an array of display indicia, and the indicia are responsive to a mapping function used to generate a displayed ultrasonic image as a modulated, non-linear, multi-bit function of at least first and second image signals. At least one of the axes of the legend varies as a function of a B-mode value range. Preferably, one axis of the legend varies as a function of a fundamental image signal, and the other axis varies as a function of a harmonic image signal. The imaging system can be controlled such that a B-mode processor automatically alternates between a fundamental mode of operation and a harmonic mode of operation on a line-by-line, group-of-lines by group-of-lines, or frame-by-frame basis. A user selects the desired mapping function as one of a series of alternative mapping functions included in a selected family of mapping functions, and the user also selects the family of mapping functions from a plurality of available families.
