Googled it. DDC1128ZKLT ADC costs 212€ a piece, but can sample at 6.25 kS/s what is way too low for this application. 8 fast 16 channel ADCs cost a fortune. They also require at least one FPGA with high pin count and these aren’t cheap either. My conclusion: decent ultrasound scanner can’t be cheap from bill of materials perspective alone.
