At the same spatial resolution, high-frequency ultrasound scattering intensity compared to the low frequency ultrasonic weak, high-frequency ultrasound image can not be obtained higher than the SNR (signal-to-noise ratio, SNR).
At the same spatial resolution, the scattering intensity of high-frequency ultrasound is weaker than that of low-frequency ultrasound, so high-frequency ultrasound images cannot obtain a high signal-to-noise ratio (signal-to-noise, SNR).
In the same spatial resolution, the scattering intensity of high-frequency ultrasound is weaker than that of low-frequency ultrasound, so high-frequency ultrasound image can not get high signal to noise ratio (SNR).<br>
