Full Matrix Capture
Full Matrix Capture (FMC) describes a pulse / receive method implemented in data acquisition hardware. There is no beam forming done in the hardware. Once the data is captured and streamed to the PC, the software must implement a post-processing or visualization algorithm. One popular processing technique is the Total Focusing Method (TFM).
The Pulse / Receive sequence is:
- Pulse on Element 1, then receive raw data on all channels in parallel without beam forming in the hardware…
- Then pulse on Element 2, receive all, pulse 3, receive all…and so forth.
One FMC for an OEM-PA 64/64 HW is 64 x 64 = 4,096 raw A-scans
Full Matrix Capture is Not to be confused with Matrix Phased Array
