transducer (redirected from sector transducer)

transducer /trans·du·cer/ (-doo´ser) a device that translates one form of energy to another, e.g., the pressure, temperature, or pulse to an electrical signal.

---

neuroendocrine transducer  a neuron, such as a neurohypophyseal neuron, that on stimulation secretes a hormone, thereby translating neural information into hormonal information.

---

Transducer

A device that converts electrical signals into ultrasound waves and ultrasound waves back into electrical impulses.

Mentioned in: Doppler Ultrasonography, Echocardiography, Endocarditis, Transesophageal Echocardiography

[-d(y)o̅o̅′sər]

Etymology: L, trans + ducere, to lead

a hand-held device that sends and receives ultrasound signals. It changes electric impulses into soundwaves, receives reflected soundwaves, and converts them back into electric energy.

transducer [trans-doo´ser]

a device that translates one physical quantity to another, e.g., pressure or temperature, to an electrical signal.

neuroendocrine transducer a neuron, such as a neurohypophyseal neuron, that on stimulation secretes a hormone, thereby translating neural information into hormonal information.

pressure transducer an electronic device that converts pressure (such as blood pressure) into electrical signals that can be recorded graphically and monitored.

transducer (tranzdoo´sur),

n a device that is activated by power from one system and then supplies a different form of power to a second system; used to convert electric energy into mechanical energy in ultrasonic and sonic scalers.

transducer

a device that translates one physical quantity to another, e.g. pressure or temperature to an electrical signal. In ultrasonography, the device that emits sound waves.

---

annular array transducer

an ultrasound transducer with crystals arranged in concentric rings with different frequencies of sound produced. It allows for a greater depth of focus.

linear array transducer

an ultrasound transducer with crystals arranged in a line. It gives a rectangular field of view.

neuroendocrine transducer

a neuron, such as a neurohypophyseal neuron, that on stimulation secretes a hormone, thereby translating neural information into hormonal information.

sector transducer

an ultrasound transducer which produces a fan-shaped field of view.
