技術摘要 / Our Technology:
A method of calibrating ultrasound velocity is provided, including receiving an ultrasound non-delayed data set; performing a beam-forming process on the ultrasound non-delayed data set with a plurality of velocities to generate a plurality of aperture images; performing a Mean Absolute Percentage Error (MAPE) process to obtain a velocity and two sub-aperture images corresponding to an MAPE value located within an MAPE range; finding a first sub-aperture and a second sub-aperture corresponding to the two sub-aperture images, generating a first aperture image and a second aperture image with corresponding velocity; performing the MAPE process on the first aperture image and the second aperture image to generate an image error corresponding figure having an error curve; finding a trend curve according to the error curve; and finding a lowest point of MAPE value on the trend curve and finding a velocity correspondingly to obtain the calibrated ultrasound velocity.
