DOPPLER SIGNAL PROCESSING UNIT AND ULTRASONIC DIAGNOSTIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To realize a Doppler signal processing unit which efficiently uses a Doppler signal to be intermittently input and to realize an ultrasonic diagnostic apparatus using such a Doppler signal processing unit. SOLUTION: The Doppler signal processing unit comprises: a first removing means (502) for removing a DC component from the intermittent Doppler signal having a predetermined time width; a window means (504) for window-processing the signal after the removal; a conversion means (506) for converting the signal after the processing into a signal of a frequency domain; and a second removing means (508) for removing the low-frequency component from the signal after the conversion.
