100
This is another name for the pulser.
What is beamformer?
100
This is the machine function which performs compensation.
What is TGC?
100
More pixels result in this kind of resolution in an image.
What is worse or reduced?
100
This is the result on an image when SNR is increased.
What is improved?
100
This is the number of shades of gray commonly believed to be visible by the human eye.
What is 64?
200
This is what is created within the pulser.
What is the scan line?
200
These are the signals which receive compensation in step 2 of the receiver.
What are far field signals (last received)?
200
This is when read zoom occurs.
What is postprocessing?
200
This is the SNR when there is low amplitude and high noise.
What is low?
200
This is another name for compression.
What are:
Compression
Dynamic Range
Grayscale
Post processing “curves” or “maps”
Display Contrast
300
This is the part of the machine which is responsible for phasing and time delays.

This is number 4 on the following image:
What is the knee?
300
This is the color of 1111.
What is white?
300
This is the display mode where the y-axis displays amplitude.
What is A-mode?
300
This is the name for a binary digit (1 or 0).
What is a bit?
400
This is the first function of the receiver.
What is amplification?
400
This is the function of the receiver which minimizes the number of shades of gray in the received signals.
What is compression?
400
The size of this determines the number of pixels.
What is matrix?
400
This is the function in which the machine assigns a grey number to a specific pixel by evaluating the neighboring pixels.
What is interpolation?
400
This is the harmonic frequency compared to the transmitted frequency.
What is double?
500
These are the signals which are subject to amplification in step 1 of the receiver.
What are all the signals?
500
This is the function of the receiver which can be additionally adjusted by the operator with wall filter.
What is rejection?
500
This is the number of shades of grey in an 8-bit system.
What is 256?
500
This is the function in which the machine adjusts a specific pixel's shade of grey based on the surrounding pixel shades.
What is spatial averaging?
500
This is the display mode in which the z-axis displays amplitude.
What is B-mode?
