Ultrasound-based liver examination device, ultrasound apparatus, and ultrasound imaging method

An ultrasound-based liver examination device, comprising:

• a receiving circuit configured to acquire an ultrasound echo signal which is obtained by scanning a target tissue with an ultrasound wave, wherein the target tissue is a tissue of a liver;
• an ultrasound echo signal processor configured to perform different processes on the obtained ultrasound echo signal according to usage of the obtained ultrasound echo signal, wherein a gain compensation for enhancing image quality is performed on a first ultrasound echo signal for obtaining an ultrasound image of the target tissue and a gain compensation for preserving original information is performed on a second ultrasound echo signal for calculating a quantitative parameter of the liver;
• and
• a data processor configured to generate the ultrasound image of the target tissue according to the processed first ultrasound echo signal and calculate the quantitative parameter of the liver according to the processed second ultrasound echo signal, wherein the quantitative parameter comprises a quantitative parameter representing an ultrasound attenuation degree in the liver, a quantitative parameter representing a difference between ultrasound echoes from the liver and another tissue, and a quantitative parameter representing an ultrasound velocity in the liver.

An ultrasound imaging method, comprising:

• transmitting an ultrasound wave to a target tissue and receiving an ultrasound echo from the target tissue to obtain an ultrasound echo signal, the target tissue being a tissue of a liver;
• performing a gain compensation for enhancing image quality on a first ultrasound echo signal for obtaining an ultrasound image of the target tissue;
• performing a gain compensation for preserving original information on a second ultrasound echo signal for calculating a quantitative parameter of the liver;
• generating the ultrasound image of the target tissue according to the processed first ultrasound echo signal;
• calculating the quantitative parameter of the liver according to the processed second ultrasound echo signal, wherein the quantitative parameter comprises a quantitative parameter representing an ultrasound attenuation degree in the liver, a quantitative parameter representing a difference between ultrasound echoes from the liver and another tissue, and a quantitative parameter representing an ultrasound velocity in the liver;
• and
• displaying the ultrasound image and the quantitative parameter.
