Experimenting with medical mechanical probes

Beware, the setup in these experiments was such as it yields raw ultrasound signals, allowing for image reconstruction, but not real-time images;

So far, I’ve had luck experimenting with a couple of mechanical probes:

  • HP 21412A: a simple piezo and motor driven relatively easily at 5V. Would you want to explore acquiring ultrasound images, this is a safe bet.
  • ATL3 probe: a great familly of mechanical probe. There are even annular ones. Great set of technology: reed switches, inductive pulses, three piezos per head.. and simple motor power supply. Plug in 5V and you’re done.
  • Bard: driven by electromagnets. Teardown is quite easy, access to the head more than easy.
  • Kretz AW14 5B A: first of the probes I’ve opened and extracted images. Can’t remember though how I powered it. Need to think.
