Embodiment 1

[0049] figure 1 It is a schematic flow chart of the method for processing liver scan images provided by Embodiment 1 of the present invention. This embodiment is applicable to the case of obtaining liver fibrosis degree parameters, and this method can be executed by a processing device for liver scan images. The device can be realized by software / hardware, and can be integrated into the ultrasonic imaging equipment.

[0050] see figure 1 , the processing method of the scan image of the liver, comprising:

[0051] S110. Acquire ultrasonic radio frequency signals of the scan region of the liver.

[0052] During ultrasound scanning, the ultrasound radio frequency signal is processed through a traditional B-mode imaging process to obtain a two-dimensional liver image. The acquired two-dimensional liver image at this time is generated based on the echo signal. All ultrasonic radio frequency signals corresponding to the region are determined according to the scanned region of th...

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and device for processing liver scan images. Background technique [0002] Ultrasound imaging has become one of the most widely used clinical diagnostic tools because of its non-invasive, real-time, convenient operation, and low price. The most basic and most important in ultrasound imaging is B-mode imaging. B-mode imaging is a two-dimensional imaging mode that converts the intensity of tissue ultrasound echo signals into gray scale (brightness), and reflects the two-dimensional section of the tissue. Morphological and structural information has the characteristics of strong real-time, good intuition, easy to grasp and easy to operate, and it is also the most widely used imaging method in clinical ultrasound. [0003] Ultrasound examination is currently the most widely used technique in clinical examination of liver diseases, and B-mode ultrasonography...
