Ultrasound transducer
Ultrasound Transducer
An Ultrasound Transducer (pronounced: ul-truh-sound trans-doo-ser) is a device that converts one form of energy into another, specifically, electrical energy into ultrasound waves and vice versa. The term is derived from the Latin ultra meaning "beyond", and the Greek sound, meaning "wave". The term transducer comes from the Latin transducere, meaning "to lead across" or "to transfer".
Function
The primary function of an Ultrasound Transducer is to emit ultrasound waves into the body and then receive the echoes produced by the waves as they bounce off different tissues and structures. The transducer then converts these echoes back into electrical signals that can be processed by the ultrasound machine to create an image.
Types
There are several types of ultrasound transducers, including:
- Linear Transducer: This type of transducer produces a linear image and is often used for vascular and small parts imaging.
- Curvilinear Transducer: This transducer produces a sector-shaped image and is commonly used for abdominal and obstetric imaging.
- Phased Array Transducer: This transducer is used for cardiac imaging due to its small footprint and ability to provide images at multiple angles.
