Abstract
Disclosed are a method, apparatus and device for calculating signal attenuation, and a computer-readable storage medium. The method comprises: receiving an ultrasound signal by an ultrasonic imaging system, performing signal recovery operation on the ultrasound signal propagating in a tissue to obtain a recovered ultrasound signal; determining a type of the recovered ultrasound signal, and calculating attenuation information of the recovered ultrasound signal by adopting a calculation mode corresponding to the type according to the type of the recovered ultrasound signal. As such, the signal attenuation calculation flow is simplified, thereby enabling use of commercial probes therein, bringing convenience in operation, and increasing applicability. Accuracy and efficiency of attenuation calculation can be improved by means of performing signal recovery on an obtained ultrasonic signal and then performing attenuation calculation thereon.
