Three Dimensional Echocardiography: History and Current Applications

Three Dimensional Echocardiography: History and Current Applications. The agreement was realized between 3D echocardiography and volumetric cine magnetic resonance imaging. There were no differences existing between the two techniques and volumetric magnetic resonance imaging. Three-dimension echocardiography was different by one functional category in just 8% of patients handled. The advantage of mass and volume calculation by 3D echocardiography over 2D echocardiography has in the recent past been observed in children having functionally single left ventricles. The measurement of volume by 3D echocardiography is more accurate and had shorter acquisition time as compared to the 2D echocardiography.The aim of three-dimensional echocardiography was to give cardiologists a more accurate rendition of the human heart as well as the face or surgical views of cardiac structures semi-invasively and non-invasively.

The images found by the interpolation and reconstruction technique, however, was cumbersome and time-consuming. This is because the process of reconstructing many 2D images into a single 3D image needed scan conversion where the scanned information had to be changed into a 3D grid, and volume rendering with interpolation to fill in the gaps resulting to the complete 3D image. A big part of this process took place over a period of 30 minutes (Lange et al 407).Apart from the clumsy acquisition process and time constraint, three-dimensional images that resulted from reconstruction were not of the quality that would be useful for diagnosis. In order to counter these limitations, Von Ramm developed an online acquisition technique in the 1990s. This technique could give details on the volume using a sparse matrix array transducer. Each piezoelectric crystal at the sparse array transducer is meant to either receive or transmit ultrasound. The elements are arranged in a grid to allow the possibility of steering the beam in many directions, thus producing a 3D full volume. This technique was further improved to be able to produce near real-time 3D images. This is what was referred to as real-time 3D echocardiography in cardiology is.  .
