Jittering in medical diagnostic ultrasound imaging is reduced, such as in steered spatial compounding. A pattern of decorrelation is used to detect motion between component frames, register component frames, and/or reduce jitter in the motion correction. The ultrasound imaging adapts as a function of the pattern.

Reducing jittering in medical diagnostic ultrasound imaging

A portable ultrasound imaging system employs a mechanically focused multi-element circular annular transducer that is mechanically scanned using a motor. Received echoes are processed to form two dimensional gray scale B mode images or two dimensional color tissue flow images which are displayed on a display unit. In case of color flow imaging, a high pulse repetition frequency imaging sequence is employed for a reasonable frame rate and special down-sampling techniques are applied to achieve an effective low pulse repetition frequency for flow estimation with enough signal to noise ratio. The system also includes a docking subsystem which charges a system battery and transfers patient and image data between a PACS system, workstation or other information system and the portable ultrasound imaging system.

An ultrasound imaging system that can automatically adjust the imaging parameters based on the original or processed received echoes from the target is presented in this disclosed technology. The adjustment is done through a closed loop negative feedback control system iteratively. Imaging performance evaluation parameters calculated from the received echoes, original or processed, are compared with preset thresholds that represent desired optimal imaging performances. The differences are used to calculate the adjustment for the imaging parameters. The system reaches to an optimal system image quality for the current target or stops when a maximum number of iterations is reached.

Method and apparatus for an automatic ultrasound imaging system

Diagnostic ultrasound flow imaging is performed with coded excitation pulses. Due to the use of frequency coded excitation pulses, flow information may suffer from spatial misregistration and estimate errors. Spatial position shift in flow data is offset for alignment with B-mode or other imaging. The flow estimates are compensated for the imaging center frequency variation with depth. The wide bandwidth information available due to coded excitation may allow anti-aliasing by estimating velocities from two frequency bands.

Methods and system for controlling an ultrasound system are described. One method includes acquiring ultrasound data relating to an object and iteratively adjusting acoustic power output of the ultrasound system based on the acquired ultrasound data.
