Abstract

The invention provides a method for extracting a liver region in an ultrasound image. The method is characterized by comprising the steps of: step 1, handling a situation of uneven illumination in the image, so that the brightness of the liver region in the image tends to be uniform; step 2, reducing noise in the image and completing image segmentation by using an FCM_I algorithm added with neighboring correlation information and priori shape information; step 3, acquiring a foreground region and a background region according to an FCM_I classification result and grey scale information; step 4, and acquiring an image of a complete liver region according to distribution and shapes of organs in a liver. The method for extracting the liver region in the ultrasound image provided by the invention improves the possible association of foreground pixels of the liver region, and reduces the association between the backgrounds of the liver region, thereby extracting the relatively complete liver region.

Description

technical field

[0001] The invention relates to a method for extracting an image of an organ region in an ultrasound image, in particular to a method for extracting a liver region in an ultrasound image. Background technique

[0002] Ultrasound examination is a technology that applies ultrasound to human body detection. It uses the human body to image the strength of ultrasound reflections, measure the shape and density of physiological or tissue structures, and find disease symptoms. Ultrasound has many advantages as a routine physical examination. First of all, it uses ultrasonic waves, which are harmless to the human body and are a safe means of inspection. On the contrary, the inspection using various rays has great harm to the human body. Secondly, the price of ultrasound examination is cheap, and the cost of an examination is usually tens of yuan, which is affordable by ordinary people. CT and MRI examinations are much more expensive. In addition, the detection acc...
