IMAGE PROCESSING
Frame correlation, line filter, mass memory, etc.
DSC
Ultrasound line scanning data stored in memory is transferred to Scan Converter for format conversion into TV format scanning.
OPTIONAL
Doppler, Color flow, additional board for an specific probe, etc.
DISTRUBUTOR
Distributor is the block that receives form outside the equipment all kind of signals and also output from the equipment signals like ultrasound images, audio from Doppler, PCG, any of these signals to red.
PHYSIO
This is the block that receives and output via the distributor physiologic signals like PCG, ECG etc.
PERIPHERIC
The peripheric are the different devices that are connected to the equipment like a PC, a printer, a DVD burner etc.

Random Quiz:
Question 1: Why is the switching PS is efficient than the linear PS? ________
a. Because do not use transformer for lowering the input voltage
b. Because are used for output low voltage
c. Because the power device consumes energy only part of the time for output
d. Because are smaller than the linear PS
Question 2: Why is every probe model has its own code? _______
a .To identify the working voltage of each one
b. To identify the focus during the transmission and reception, the frequency
of transmission and reception Doppler capability, etc.
c. To prevent the use of other manufacturers probes
Question 3: Why if useful create a focal zone in transmission? ________
a. To permit the echoes to go deepen
b. To create a zone of higher refletion
c. To improve the image quality
d. To improve the axial resolution
Question 4: What is the function of the (TGC) Time Gain Compensation? _______
a. To apply a logarithmic amplification to the echoes for compensating the
attenuation as the echoes go deep inside the human body
b. To set all the echoes to the same amplitude no matter how deep they
come from
c. To delay the echoes coming near the probe
Question 5: What is the function of the (DSC)? _______
a . Format conversion into TV format scanning.
b. To set all the echoes to the same amplitude no matter how deep they
come from
c. For improve the quality of image on the monitor
