摘要： Twinkle artifacts are suppressed in color flow. The color flow data itself, such as temporal decorrelation and spatial variance of the velocity and/or power, is used to identify the twinkle artifact. The aliased or high velocities caused by the twinkle artifact are suppressed, such as by reducing the velocity or by spatial filtering that adapts to the locations of the artifact. The powers caused by the twinkle artifact are suppressed.

摘要： Responsive power saving is provided for ultrasound imaging, such as in portable ultrasound systems. By reducing scan line density in response to removal of a transducer from a patient, power usage may be reduced while still monitoring for return of the transducer to the patient. By disabling the display, power usage may be reduced while still monitoring for return of the transducer to the patient. All or most electronics not associated with monitoring for the return of the transducer to the patient may be disabled or not used to conserve power.

摘要： Gap filling is provided in spectral Doppler ultrasound. Due to the cyclical nature of the cardiac system, data likely to be similar to data that would have been acquired without interleaving is copied into the gap generated by interleaving. Acquired data associated with the gap, such as adjacent to the gap, is correlated with other acquired data. By identifying similar data, acquired data temporally related to the similar data as the gap associated data is temporally related to the gap is found. This found data is likely to be similar to data that would have been acquired during the gap. The gap is filled with a copy of this data.

摘要： Sidelobe and clutter suppression techniques in ultrasound imaging are described and referred to as Dual Apodization with Cross-correlation or “DAX”. DAX dramatically improves the contrast-to-noise ratio (CNR) allowing for easier visualization of anechoic cysts and blood vessels. These techniques use dual apodization or weighting strategies that are effective in removing or minimizing clutter and efficient in terms of computational load and hardware/software needs. This dual apodization allows for determination of the amount of mainlobe versus clutter contribution in a signal by cross-correlating RF data acquired from two apodization functions.
