Ultrasound B-mode and doppler flow imaging

摘要

An ultrasound scanning system (10) includes a plurality of range gates (71-74) responsive to ultrasound waves for generating a plurality of Doppler signal samples representing different depth increments within a subject (S) being studied. A logic unit (30) generates Doppler frequency signals and generates B-mode data. A display (60) generates a B-mode image and a Doppler image which may be superimposed on the B-mode image. The Doppler image (DI) is arranged to illustrate depth increments within the subject being studied versus Doppler velocity or frequency.
