Title:
CONTROL DEVICE AND CONTROL METHOD OF ULTRASONIC DIAGNOSIS DEVICE
Document Type and Number:
Japanese Patent JP2018075142
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a control device of an ultrasonic diagnosis device that can suppress mixing of switching noise into a Doppler shift frequency detection result.SOLUTION: A control device 10 of an ultrasonic diagnosis device includes: an operation mode setting part 10b for setting at least first and second operation modes as objects to display an observation result in a screen simultaneously from a plurality of operation modes with different pulse waveforms of ultrasonic pulses to be transmitted; an operation type setting part 10c for setting an operation type that regulates a transmission timing of each ultrasonic pulse of the first and second operation modes; and a switching frequency setting part 10d for setting a switching frequency of a switching signal so that a fundamental frequency and a harmonic wave of the switching signal when driving a switching power source 12 is not included in a Doppler observation frequency band determined based on the first and second operation modes and operation types.SELECTED DRAWING: Figure 1
