Flow characteristic imaging in medical diagnostic ultrasound

摘要

Flow is characterized in medical diagnostic ultrasound imaging. The flow information over time for each spatial location may be broken down (36) into component parts using Fourier analysis. For example, the average or steady state component of the flow at each location may be determined (37) and used for imaging (40). The first harmonic may likewise be used. Imaging using one or more component parts of the flow information over time may provide diagnostically useful information. In addition or independently, the flow information may be analyzed to identify (42) a vortex. The vortex characteristics may provide diagnostically useful information.
