Been working on a MAX14866 MUX - allowing to drive 8 transducers separately on the Tx and/or Rx path. Not so bad, I've managed to plug a 5-ring annular element and run some tests. I assume some connections need to be reviewed, as not all paths seem connected.

Setup. Inclusion at 15-30mm depth.

Images for 25 pairs of piezos (5 piezos, 1TX/1RX each time)

Filtered

Details of the bottom of the phantom at 50mm

Some fun ahead!
