Ultrasound Transducer Types . It can be used for abdominal examinations. The transducers are also useful in emergency and mobile settings, as they are portable and lightweight. As a result, ultrasound offers medical imaging professionals a safe and quick option in certain cases, although it has its limitations. Transducer types and associated scanning and image formats: A, linear array; B, phased array; C, convex or curved array; D, endo array; E, 2D or matrix array; F, mechanically scanned linear array; G, mechanically scanned convex array; and H, intravascular ultrasound transducer (courtesy of Boston Scientific, GE Healthcare, and Philips Healthcare). Curvilinear ultrasound probes also know as convex probe are low-frequency transducers. Ultrasound transducers that are used to scan over the surface of the skin are referred to as external (or surface) transducers. The more important ones are footprint and frequency. Each element is equal to or less than a ½ wavelength wide and transducer length is generally 5 to 15 cm. High frequency transducers are single element contact or immersion transducers designed to produce frequencies of 20 MHz and greater. Most people are familiar with using ultrasound for prenatal care and to observe the fetus as it develops. However, the density of the scan lines reduces as the image depth increases, which means you might have to compromise on the image quality. The probe is an important accessory in an ultrasound. Low-frequency US with Ultrasound Transducer Types and How to Select the Right Transducer (Updated 2019) – What is an ultrasound transducer and what does it do? Convex Transducers  The convex ultrasound transducer type is also called the curved transducer because the piezoelectric crystal arrangement is curvilinear. Intravascular ultrasound (IVUS) is one of the most useful tools available today to assist intravascular stenting procedures. In accordance with the needs of each ultrasound procedure, transducers come in different configurations and sizes. Convex probes also have a subtype called micro convex probes. Linear (also sometimes called vascular) probes are generally high frequency, better for imaging superficial structures and vessels, and are also often called a vascular probe. Physicians and medical imaging staff should take into account the unique features of each ultrasound probe. It is ideal for scanning small windows such as the cranial window in the temple or for cardiac imaging. Endocavitary transducers are commonly used in internal examinations of the patient. There are various electrical and electronic components are used to build the circuits and projects for engineering students. The probe is an important accessory in an ultrasound. However, the image resolution of the convex transducer decreases as the depth increases. Depending on whether the linear transducer is for 2D or 3D imaging, the footprint, applications, and frequency may change. We're so confident in the durability of our ultrasound transducers that we created an industry-first warranty to cover them. Ultrasound therapy also uses high-frequency sound waves but does not produce images. Targeted microbubbles and plasmid IFN-β (pIFN-β) are mixed and intratumorally injected. The frequencies can be anywhere between 1 and 18 MHz, though frequencies up to 50–100 megahertz have been used experimentally in a technique known as biomicroscopy in special regions, such as the anterior chamber of the eye. These investigators also showed that this system had potential for peripheral arterial clot dissolution in vivo in anima … This decision involves two components – choosing the right ultrasound according to your needs and the perfect transducer or probe (s)  for your ultrasound.
