Drag and Drop

The basic principle of ultrasound:

The

(aka probe) produces

waves. These waves enter tissues. Tissues have different

, which affect the intensity and speed of the waves. The sound can be

by the tissue, reflected by the tissue, or scattered by the tissue.

Tissues have different densities. What are the three things that can happen to an ultrasound wave when it reaches a tissue?

Transmission, scattering, and reflection

Reflection, refraction, and distortion

Absorption, refraction, and emission

Reflection, absorption, or scattered.

Multiple Choice

Which of the following is like the "volume" know on an ultrasound?

Image contrast

Gain control

Depth control

Frequency adjustment

Multiple Choice

Gain modifies the ____________________ and therefore affects the brightness of the image.

strength of the returning echo

frequency of the ultrasonic waves

colour saturation of the doppler image

Drag and Drop

Too little gain = image will be too

Too much gain = image will be too

Multiple Choice

What does Time-Gain Compensation do?

Adjusts signal gain based on the time delay to improve image clarity.

Eliminates all noise from the signal.

Is used to increase the size of the image.

Reduces image resolution for faster processing.

Multiple Choice

What does the "depth" knob control on an ultrasound?

Changes the color of the ultrasound image.

Adjusts the volume and amplitude of the ultrasound sound waves.

Sets the frequency of the ultrasound waves.

Adjusts how far the transducer can send and receive sound waves.
