An Overview of Ultrasound Transducers

When we talk of ultrasound machines, ultrasound transducer stands out as one of the most vital component of the general imaging mechanism as without this component images cannot be obtained in any other way. Coming to their mechanism of working, a high frequency sound wave is sent inside the patient’s body through a probe which has a set of sensors attached to its body. Now, the sensors senses the movements and different physical specifications of the body parts and sends back the obtained data to the transducer which converts the obtained data to electrical data in human readable form in the form of images which in turn is processed and displayed through the monitor. So, it is pretty obvious that in absence of the transducer, the much required data conversion from sound to image form cannot be achieved anyway which makes their role imminent and vital in this context. There are several different types and varieties of the ultrasound transducers, with the differences being based on the part of the body to be examined. To elaborate on this subject, the shapes and sizes are commonly governed by the body part to be treated. For example, for abdominal diagnosis, frequencies falling within the range of 2MHz to 7.5MHz is used whereas for viewing thyroid glands, frequencies of around 10MHz is used whereas in case of detecting pregnancies, a relatively lesser frequency is used as higher frequencies have been proved to have left a negative effect on both the mother and the baby. Depending on the purpose of use, transducers are designed in different shapes and specifications for subsequent forms of treatments and healings. Some of the best quality products come with dual or even greater number of specifications but operating them is never going to be that easy, especially for the new and the non technical users
