3D-Mode
1.) CPC
see:
5-2-4-1 B-Mode
2.) CPR
see:
5-2-4-1 B-Mode
3.) CPG
see:
5-2-4-1 B-Mode
4.) CPF
Arranges the CFM-Processing. WMF (Wall Motion Filter), Autocorrelator, Post-processing.
(In case that 3D-Color is active, else CPF not used)
5.) CPS
Data from CPG and CPF go to both:
a.) to the LineMemory,...FrameMemory,...CKV (see:
5-2-4-1 B-Mode
) and
b.) via DMA-Controller and PCI-Bus to the PC-Memory.
The way from the Line Memory to the CKV is the same as in B-Mode.
This is the only case that the Line Memory-Frame Memory-Path is active in context with 3D-Mode
and Real Time 4D-Mode – just for displaying the actual scanned 3D-Acquisition Sweep-B-Frame.
All other displayed B-Frames in 3D-, 4D- or SonoView-Mode are PC-generated and do not need
CPS any more.
6.) CKV

Real Time 4D-Mode
1.) CPC

5-2-4-1 B-Mode
2.) CPR
see:
5-2-4-1 B-Mode
3.) CPG

4.) CPF
Arranges the CFM-Processing. WMF (Wall Motion Filter), Autocorrelator, Post-processing.
(In case that 4D-Color is active, else CPF not used)
5.) CPS
In Real Time 4D the signal path is even simpler than in 3D, because we do not have to display the
actual scanned 3D-Acquisition Sweep-B-Frame. Data from CPG and CPF go via DMA-Controller
and PCI-Bus to the PC-Memory.
All displayed B-Frames are PC-generated and do not need CPS any more.
