With the advancement in technology and science, machines and other equipment have also developed.
The latest innovations and inventions are applied in medical science to make things easier to diagnose problems and ailments of people. One such development in science is that of a cardiac ultrasound scanner. With gradual inventions and research, the machine’s features and utility is also enhanced.
Cardiac ultrasound, also known as echocardiography, is concerned with the ultrasound imaging of a very fast moving complex organ positioned deep within the body - the heart. It uses standard two-dimensional, three-dimensional, and Doppler ultrasound to create moving pictures of the heart with sound waves. It is neither a surgery nor does it hurt; it is only a test. Technological advances over the past decades have made ultrasound equipment quite portable, with functionality and good image quality. More recently, pocket-size ultrasound devices have been developed by various vendors. There has been a speedy development from a hand carried device to a portable ultrasound scanner. These devices have sizes just as those of mobile phones and are equipped with a battery and a single transducer. Although these devices currently do not have advanced features such as spectral or tissue Doppler, they allow for gray-scale imaging and color-flow Doppler: they are also capable of recording both still images and video clips. These attributes, along with their low cost, allow providers to use these devices like a stethoscope of the future. The greatest good point of echocardiography is that it is noninvasive and has no known effects or reactions.
The sonographer will make you to lie on a bed on your left side or back and will then put special jelly on a probe and move it over your chest area. Your heart’s movements can be seen on a video screen. An echocardiography examination generally lasts between 15-30 minutes.
Two-dimensional (2-D) echocardiography provides real-time imaging of the heart structures throughout the cardiac cycle. The recent development in cardiac ultrasound is that of 3-dimensional (3-D) echocardiography. Doppler echocardiography provides information on blood movement inside cardiac structures and on hemodynamics. Doppler Echocardiography is a method by which one is able to identify the direction and velocity of blood flow.
Tissue Doppler imaging (TDI) provides information about movement of cardiac structures. The relation between the dynamics of cardiac structures and the hemodynamics of the blood inside these structures provides information about cardiac diastolic and systolic function. Echocardiography is continuously evolving and constantly being augmented by newer modalities, such as tissue harmonics, speckle tracking, tissue Doppler strain, and tissue characterization. A Doppler ultrasound test may also help your doctor check for injuries to your arteries or to monitor certain treatments to your veins and arteries.
Technological developments in cardiac ultrasound are expanding the application of echocardiography in the evaluation of cardiac disorders. In addition to improvements that directly influences imaging capabilities, newer ultrasound systems are lighter, easier to transport, and consumes less physical efforts and produces better results. Not only you can purchase a new machine but also you can get
used cardiac ultrasound machines. Giving it these advantages, this scanner will gradually come into the hands of the ones who do not even know how to use it.
