Sonographic Physics Chapter 12: Arrays and Transducers

What kind of transducer uses simple A-Mode machines and mechanical scanning transducers?

• Single Element Transducers

• Multi Element Transducers

• Mechanical Transducers

• Electronic Transducers

What shoots a straight beam into tissue?

• PZT

• Crystals

• A single crystal

• A simple transducer

What does the returning echoes create?

• Vibration

• Images

• Straight line

• Oblique line

How can you get a slice of tissue while using a straight line?

• Sweeping

• Rocking

• Tilting

• Sliding

How can we get the beam to sweep from one direction to another without having to move the probe?

• Beam

• Motor

• Transducer

• Wire

This is a single, circular, disc-shaped active element mounted on a motor

• Electronic Transducer

• Mechanical Transducer

• Single Element Transducer

• Multi Element Transducer

What is the shape of the mechanical transducer?

• Fan or sector

• Squared

• Straight

• Oblique

The scan lines on the mechanical transducer will

• converge with depth

• narrow with depth

• widen with depth

• diverge with depth

If the crystal becomes defective the entire image is

• ruined

• lost

• damaged

• partly ruined

On a mechanical transducer, each rotation created a single scan or

• depth

• zoom

• frame

• gain
