Ultrasound transducer

Ultrasound transducer

An Ultrasound transducer is a device that converts one form of energy into another, specifically, it converts electrical energy into ultrasound waves and vice versa. It is a key component of ultrasound imaging systems, which are widely used in medical imaging and diagnostic medicine.

Function

The primary function of an ultrasound transducer is to emit ultrasound waves and then receive the echoes of these waves. This is achieved through the piezoelectric effect, where certain materials generate an electrical charge in response to mechanical stress. In the case of an ultrasound transducer, the piezoelectric material generates an electrical signal when it receives the mechanical pressure of the returning ultrasound waves.

Types

There are several types of ultrasound transducers, including linear, convex, phased array, and endocavitary transducers. Each type has a different shape and is used for different types of ultrasound examinations.

Linear transducer

A Linear transducer is a high-frequency transducer that provides high-resolution images of superficial structures. It is often used for vascular, small parts, and musculoskeletal imaging.

Convex transducer

A Convex transducer, also known as a curved transducer, is a low-frequency transducer that provides a wide field of view. It is often used for abdominal, obstetric, and gynecologic imaging.

Phased array transducer

A Phased array transducer is a small, low-frequency transducer that provides a wide field of view. It is often used for cardiac and transesophageal imaging.

Endocavitary transducer

An Endocavitary transducer is a high-frequency transducer that provides high-resolution images of internal structures. It is often used for gynecologic, obstetric, and prostate imaging.
