Ultrasonic diagnosis device and method capable of recognizing liver cancer automatically

Abstract

The invention discloses an ultrasonic diagnosis device and a method capable of recognizing liver cancer automatically. The method includes the following steps: an area of a detected body is scanned by ultrasound, wherein the area includes at least one part of the liver; an echo signal of the liver part is obtained through an ultrasonic sending unit and an ultrasonic receiving unit; a pre-processing unit pre-amplifies the signal and converses the signal from analog to digital; a signal processing unit processes the signal with demodulation, digital scanning conversion (DSC), noise-reducing, filtering and the like; an image synthesis unit produces an ultrasonic image of the liver area; an image computing unit analyzes texture of the obtained ultrasonic image and recognizes liver cancer tissues in the image; and at last the liver cancer tissues are displayed in an image display unit. The ultrasonic diagnosis device and the method are capable of recognizing cancer tissues automatically by extracting texture features of the ultrasonic image and diagnosing the occurrence and the development of cancer assistantly. Further, the ultrasonic diagnosis device and the method are convenient and high in accuracy.

Description

Technical field: [0001] The present invention relates to the field of medical image processing, in particular to an ultrasonic diagnosis device and method for automatically identifying liver cancer, in particular for detecting diseased tissue in medical images. Background technique: [0002] Liver cancer is one of the most common malignant tumors. In China, the mortality rate of liver cancer ranks second, after lung cancer. Early diagnosis and treatment are important measures to reduce the mortality rate of liver cancer patients. Liver cancer can be detected early through medical imaging equipment. Ultrasonography has the advantages of simple operation, no radiation, and real-time performance. It has always been regarded as the screening and diagnosis of liver entities. It is the preferred method of examination for orthotopic lesions and plays a huge role in the identification and diagnosis of intrahepatic lesions. In reality, sonographers have to receive many patients ever...
