ADAPTIVE DEMODULATION METHOD AND APPARATUS FOR ULTRASOUND IMAGE |
| 摘要 |
Disclosed are a method and an apparatus, which enhance a quality of an ultrasound image to provide an improved image. An adaptive demodulation method includes acquiring input radio frequency (RF) data, quadrature-demodulating the input RF data to output an inphase-quadrature (IQ) signal, determining a valid region for the input RF data, and estimating attenuation of a frequency of the IQ signal, based on data included in the valid region among the input RF data and performing frequency compensation corresponding to the estimated attenuation of the frequency. |

1. An adaptive demodulation method comprising:
acquiring input radio frequency (RF) data; quadrature-demodulating the input RF data to output an inphase-quadrature (IQ) signal; determining a valid region for the input RF data; and estimating attenuation of a frequency of the IQ signal, based on data included in the valid region from among the input RF data and performing frequency compensation corresponding to the estimated attenuation of the frequency. |
