Title:
Ultrasonic diagnostic equipment and a noise reduction method for the same
Document Type and Number:
Japanese Patent JP6166255
Kind Code:
B2
Abstract:
This ultrasonic diagnostic device is provided with a control unit for performing control to satisfy the numerical formula below by controlling at least one from among a reference wave frequency (Fref), a switching frequency (Fsw), and a sampling frequency (Fadc), and the ultrasonic diagnostic device removes removal components (for example, clutter components) appearing near the reference wave frequency (Fref) and removes noise. Fref=n*Fsw (n-1)*Fsw<=Fref-(1/2)Fadc Fre+(1/2)Fadc<=(n+1)*Fsw N: positive integer Fref: reference wave frequency Fsw: switching frequency Fadc: Sampling frequency
