Detection Method of Three-Dimensional Echocardiography Based on Deep Learning

In order to improve the detection and recognition ability of 3D echocardiography, a method of 3D echocardiography detection based on depth learning is proposed. The information conduction model of three-dimensional echocardiography is constructed. The edge pixel feature matching method is used to extract the key information of echocardiography, and the information compensation method is used to repair the missing area of three-dimensional echocardiography information. The feature decomposition and information fusion of 3D ultrasonic imaging are carried out by using five stage wavelet decomposition method, and the feature reconstruction and adaptive template matching of 3D echocardiography are processed by depth learning algorithm, modeling and detecting the rationality of three-dimensional echocardiography. The simulation results show that this method has better detection performance; the accuracy of detection and recognition is high, which is more reasonable in the application of 3D echocardiography repair and detection recognition.

Rheumatic Heart

Rheumatic heart disease (RHD) remains to be a very important health issue worldwide, mainly in underdeveloped countries. It continues to be a leading cause of morbidity and mortality throughout developing countries. RHD is a delayed non-suppurative immunologically mediated inflammatory response to the throat infection caused by a hemolytic streptococcus from the A group (Streptococcus pyogenes). RHD keeps position 1 as the most common cardiovascular disease in young people aged <25 years considering all the continents. The disease can lead to valvular cardiac lesions as well as to carditis. Rheumatic fever valvular injuries lead most commonly to the fusion and thickening of the edges of the cusps and to the fusion, thickening, and shortening of the chordae and ultimately to calcification of the valves. Valvular commissures can also be deeply compromised, leading to severe stenosis. Atrial and ventricular remodeling is also common following rheumatic infection. Mixed valvular lesions are more common than isolated valvular disorders. Echocardiography is the most relevant imaging technique not only to provide diagnostic information but also to enable prognostic data. Further, it presents a very important role for the correction of complications after surgical repair of rheumatic heart valvulopathies. Three-dimensional (3D) echocardiography provides additional anatomical and morphofunctional information of utmost importance for patients presenting rheumatic valvopathies. Accordingly, three-dimensional echocardiography is ready for routine use in patients with RHD presenting with valvular abnormalities.

And Function

Three-dimensional (3D) echocardiography allows the real-time acquisition of volumes containing entire cardiac structures. The analysis of 3D volumes does not require any assumptions as to the shape of structures.3D echocardiography is more accurate than two-dimensional (2D) in the assessment of left ventricular (LV) volumes, mass, and function, and is comparable to cardiac magnetic resonance imaging. This makes it an ideal modality for measuring LV function particularly when this will determine significant interventions such as implanting of cardioverter/defibrillators, biventricular pacing, and the commencement and continuation of cancer chemotherapy. 3D echocardiography makes it easy to visualize valves and define pathological mechanisms. 3D assessment of dyssynchrony, myocardial strain, and stress imaging are attractive.However, 3D echocardiography is limited by the need for specialist software and lower spatial and temporal resolution when compared to 2D echocardiography.

Three Dimensional Echocardiography

With the advent of live/real time three-dimensional (3D) echocardiography, 3D imaging as a research tool has evolved to a clinical mainstay. In this review, we discuss procedures for and application of 3D echocardiography to specific clinical questions. Although contemporary application remains primarily for assessment of left ventricular function, we review many more uses for this truly revolutionary technique.
