A very important reason why the New Zealand Medical Journal is considering naming ultrasound as the most important piece of medical equipment in use today is its medical use in echocardiography fetal. When 3D ultrasound is used, there are 3 stages that must be considered separately; volume acquisition, glass body with color Doppler and rendering. First, 3D volume acquisition is a key technique that uses ultrasound when examining the fetal heart. This technique contains digital information about cardiac structures and their spatial arrangement; therefore, cross-sectional views can be obtained in any desired orientation, direction and depth. An example of this is the reconstructed heart volume displayed as a single real-time hypothetical cardiac cycle played in a cine loop, which can be played in slow motion or stopped at any time for detailed analysis of specific parts of the heart. shown below in figure 1. According to Springer writing in Echocardiographic Anatomy in the Fetus (2008) Studies on multiplanar analysis of a cardiac cycle in a remote station using STIC (slow image slice acquisition) which supports average volume from 7.5 s to 15 s. the acquisition has proven reliable in the evaluation of different cardiac planes, in screening studies and in the evaluation of fetal heart anomalies, using a volume for an Internet link. Evaluation is also emphasized, possibly allowing a second opinion in the future, this technique using ultrasound allows doctors and surgeons to see into the heart of the fetus and have a detailed picture of the heart and see if there is has problems and, if so, to enable them to operate accurately and efficiently. 3D volume acquisition allows for safer and more detailed analysis...... middle of paper ......ar septal communication, this also made it possible to demonstrate the caliber and relative position of the large arteries and d Other congenital heart diseases, these examples allow doctors and surgeons to prove whether or not the fetus has abnormalities inside the heart or abnormal growths, allowing fetuses to be operated on sooner rather than later, when the heart may not be inoperable. These are other key facts that make ultrasound a great nomination for the New Zealand Medical Journal as the most important piece of medical equipment in use today. In conclusion, volume acquisition, glass body with color Doppler and rendering are key techniques used in echocardiography through the use of ultrasound. The last point is perhaps the most important, because rendering proves whether fetuses have heart defects, allowing doctors and surgeons to operate and save lives..
