Patent ID: 8019141

Claim:
A scan conversion method for color ultrasonic imaging, comprising: a storage step for storing ultrasonic echo data; a coordinate conversion step for performing coordinate conversion between an imaging coordinate system and a scan coordinate system; and an interpolation step comprising a substep of interpolation between neighboring points, for obtaining ultrasonic echo data of an interpolation point by interpolating ultrasonic echo data of the neighboring points, wherein the interpolation step further comprises a substep for determining whether or not aliasing is occurring in the ultrasonic data of the neighboring points and a substep for correcting ultrasonic echo data, wherein if aliasing is found to be occurring, the substep for correcting ultrasonic echo data is performed followed by the substep of interpolation between neighboring points; otherwise, the substep for correcting ultrasonic echo data is bypassed and the substep of interpolation between neighboring points is directly performed.
