In the last post on 2D Echocardiography in Mumbai, we have discussed about how transducers work. Let us now learn a little further about different type of transducers and their functioning. Transducers may be classified according to two main aspects; its frequency and the technology used for the manipulation of the ultrasound beam. Transducer frequency is probably the most important feature that decides which probe is going to be used in a given echo examination. The higher the frequency, the better is the resolution of the output image. But ultrasound penetration shall be poorer in this setting. So we have to strike a balance between the resolution required in the image, and the depth at which we need to examine the tissues. Given a choice, we will always prefer to use a probe that has the highest frequency, because that will give the best image resolution. But this is not always possible. For neonates, where the chest wall is thinner, we may use a probe that has a higher frequency; usually between 7 – 7.5 MHz. But on children we may not use these high frequencies. So, we use a probe that has a frequency between 3.5 – 5 MHz. In case of adults, we can use probes that have a much lower frequency; that is, between 2 to 2.5 MHz. Reputed diagnostic centers like those run by Way2Health India, which are highly recommended by doctors for the best services in 2D Echocardiography in Mumbai, would always be accurate in choosing the right probes with the right frequencies for each echo exam, as it is a matter of sufficient experience. As mentioned earlier, another aspect that determines what kind of transducer is going to be used for a particular echo examination is the technique that is used for the manipulation of the ultrasound beam. Earlier echocardiography machines had provision for imaging in only one direction; only one line. With this, it was not possible to obtain a cross-sectional image of the heart. So, it was necessary that a mechanism is developed to move the beam from one end to the other, so that the entire image of the heart could be generated. The earlier most devices were fitted with mechanical motors. These motors used to oscillate or rotate the elements, so that the ultrasound beam could be moved from one end of the sector to the other end. But these probes were very bulky and were prone to causing malfunction of the motor. So, these probes were given up and the probes used today use electronic mechanisms for manipulation of the beam. Way2Health India is not only reputed as the best service provider of 2D Echocardiography in Mumbai, but is also renowned for the state-of-the-art equipment they use.
