This imaging system function CANNOT be altered by the sonographer.
The purpose of this receiver function is to equalize echo amplitudes from all depths.
This imaging system component coordinates and organizes the other imaging system components.
What imaging receiver function processes the received signal into a video signal?
What system control is related to the sound intensity that is delivered to the patient?
To improve the signal to noise ratio, what system adjustment should be made?
If all of the echoes on the image display are too high in amplitude, what adjustment should the sonographer first make?
If noise is present in the image, what control should the sonographer use to suppress it?
If only the echo information that is located in the far field of an image can be visualized, what adjustment should the sonographer make?
A reduction in the ratio of echo signal amplitudes is made using?
An ultrasound image containing many shades of grey is altered to appear more “black and white”, showing greater contrast. What function was used to achieve this change?
The amplifier increases the voltage amplitudes of the returning signals.
