Abstract:
Vector flow imaging(VFI)is an innovative ultrasound flow measurement technology.Compared with the traditional color Doppler and spectral Doppler,VFI has the advantages of independence of angle correction and direct acquisition of real-time amplitude and direction of flow.Transverse oscillation(TO)method is one of the effective methods for vector flow imaging.However,a complete and detailed algorithm validation process based on commercial ultrasound machines is still lacking due to more complex convex probes.This study starts with introducing the imaging process and principle of transverse oscillation vector flow technique,and calculates the error between the set velocity value and the measured velocity value through the simulation experiment,and verifies the error between the set velocity value and the measured velocity value through the Doppler flow phantom experiment.Among them,the velocity value measured by the TO vector flow technique in the simulation experiment is 0.48 m/s and the preset value is 0.50 m/s,the error between them is-4％.The velocity values are 8.33,11.14,14.44 and 16.67 cm/s measured by the Doppler flow phantom experiment,the actual velocity values are 7.97,10.78,14.06 and 17.34 cm/s,the errors between them are all within±5％.Both experiments verify the feasibility of using vector flow technique on abdominal convex probe.
