摘要:
A method for generating an ultrasound image includes receiving an image frame having consecutive ultrasound scan lines obtained using a rotating ultrasound imaging arrangement and determining first and second cross-correlation values for a plurality of the scan lines. For each individual scan line, the first cross-correlation value includes a cross-correlation coefficient between a first subframe of consecutive scan lines including the individual scan line and a second subframe of scan lines shifted from the first subframe by a first integer value. The second correlation value includes a cross-correlation coefficient between the first subframe and a third subframe of scan lines shifted from the first subframe by a second integer value. The method further includes evaluating, individually for multiple scan lines, whether that scan line exhibits non-uniform rotation distortion using at least one of the first and second cross-correlation values. A correction for non-uniform rotation distortion is applied.
