Problems solved by technology

However, all the above-mentioned research work is based on the registration of the three-dimensional cardiogram data of the same person, and can only achieve the registration of two volume data changes within a certain range, and it is often invalid for two volume data with large changes.
3D registration has a large amount of calculation and poor real-time performance

Abstract

The invention relates to a method for realizing the three-dimension ultrasonic cardiogram four-chamber section image automatic check, which comprises that 1, extracting one three-dimension data from the end-diastolic phase of heart from the heart full-volume data; 2, extracting 180 section images from the three-dimension data to build an image database; 3, calculating out the similarity between each image of database and the template image, to be selected and using wavelet system statistic character to check out the image with highest similarity in the left image, to record the position in the data as the four-chamber watch position. The invention realizes the automatic search function of four-chamber section; therefore, medical staff can use real-time three-dimension ultrasonic technique to diagnose the patient.

Description

Technical field [0001] The invention relates to a method in the technical field of computer application, in particular to a method for automatically detecting four-chamber section images of three-dimensional echocardiography. Background technique [0002] Real-time three-dimensional ultrasound system is currently the main tool for diagnosing heart disease. It realizes the function of observing the structure and movement of the whole heart, and can observe the conditions inside the heart by selecting any section. At present, doctors mainly look for two-dimensional slices one by one in three-dimensional echocardiography based on experience to observe the distortion inside the heart. Many literatures have reported the importance of the four-chamber view for the diagnosis of heart disease; for the current clinical diagnosis of real-time three-dimensional echocardiography, doctors are also the first to look for the four-chamber view for observation. However, it is difficult for unskil...
