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.

Instrumentation A device that transforms one form of energy to another–eg, a photocell that converts light into electrical energy; it is the major component in ultrasonographic devices, and contains an emitting and receiving piezoelectric crystal

(trans-doo'ser, tranz-, -du') [L. traducere, transducere, to lead across]
1. A device that converts one form of energy to another. The telephone is an example. It is used in medical electronics to receive the energy produced by sound or pressure and relay it as an electrical impulse to another transducer, which can either convert the energy back into its original form or produce a record of it on a recording device. Synonym: probe
2. In ultrasonography, an electromechanical device that emits high-frequency sounds and receives their echoes.

pulse-echo transducer

An ultrasonic transducer that sends out intermittent (pulsed) signals rather than continuous sound waves and receives the echo signal. Pulsed-wave Doppler ultrasound is used to measure blood flow and the depths from which echoes originate.

continuous wave transducer

An ultrasonic transducer that sends a constant and continuing signal that is not pulsed.

transrectal transducer

A cylindrical ultrasonic transducer inserted into the rectum to evaluate the prostate, rectum, and urinary bladder and to guide prostate biopsy.

In conclusion, this study reports the effectiveness of a protocol used in our institution to process the linear array transducer and ultrasound system that is used for peripherally invasive single-shot ultrasound-guided nerve blocks.
Over a four-week period, 120 swabs were taken from multiple sites on our ultrasound machines and linear array transducers for microbial culture.
Transducer options include an adult phase-array transducer for cardiac applications, a curved array transducer for abdominal and obstetrical (OB) scanning; a linear array transducer for imaging of the breast, small body parts, and nerves, as well as vascular intima-media thickness (IMT) measurement; an intracavitary transducer for OB and gynecologic (GYN) examinations; and a transesophageal probe for transesophageal echocardiography scanning.
