Ultrasound transducers also called probes are important components of ultrasound systems, which generate and receive sound waves to provide images of the body's internal tissues and organs. Ultrasound probes are developed for certain purposes and have distinct characteristics to improve image quality. Here are the most common types of ultrasound transducers:
1 1- Linear transducer (also sometimes called vascular)
It is a high-frequency
transducer to improve image quality and a rectangular beam with excellent
near-field resolution. With a shape of flat array and appearance. Used in examining
the vascular,
breast, thyroid, and tendon.
2-Convex transducer also called curvilinear
It is a curved array-shaped probe with a wider and deeper field of view, ideally for abdominal examinations. It is also used for examining OB/GYN, vascular, nerve, and musculoskeletal.
3-Phased array transducer
It features a narrow, triangle-shaped beam and weaker near-field resolution than many different kinds of probes. However, it provides greater depth for imaging the heart. Most frequently used for cardiac and trans-cranial examinations.
There are also a variety of specialist transducers available, including:
1-
Endocavitary transducer
It is a “U” shaped lens and array but due to their form, endocavitary probes have a limited depth range, but they may cover a larger region than convex probes. It is applied for Internal examinations of the body, such as endovaginal ultrasounds.
2-
Transesophageal echo (TEE) transducer
It is intended to be introduced into the oesophagus and view the heart from behind. This type of probe can move in four distinct directions, which are managed by handle controls. It provides a clear view of the heart without the lungs and ribs getting in the way.
3- 3D/4D
transducer also called volume transducer.
It is a moving probe with the ability to sweep the motion of the array and show slices of images from various angles. It is applied in creating 3D still images or 4D live images, also it is used for cardiac and OB/GYN imaging.
