Objective
The objective of this project is to propose an open-source, low-cost dev-kit ultrasound imaging to allow scientists, academics, hackers, makers or open hardware fans to hack ultrasound imaging.
What approach ?
- Going back to the time when ultrasound was all mechanical.
- Having a modular "approach"
- Simplify !
Bases of ultrasound imaging
Signals
Architecture
Proof of concept
Cost of the set: 325$
- A probe on ebay: 75$
- High voltage module: 80$ of components
- Analog processing module: 80$ of components
- PCBs: 40$
- Acquisition Raspberry Pi: 40$
- Raspberry Pi: 10$
Example of a probe image
Usage examples
- 2-D mode imaging
- Measurements (bladder, ...)
- Biofeedback for stroke recovery
- Doppler
- ...
Limitation and opportunity
Limits
- Material is not certified
- Probe sensor limits the quality
- Be careful!
Opportunity
- Using a Raspberry is cool!
- An open plat-form!
Lessons
What I learned tinkering with stuff
- Build the tools you need
- Document
- Do and share
Build the tools you need..
Acquisition
- BeagleBone PRU-DAQ
- BitScope
- STM32 Feather WICED
- ... custom made with a raspberry!
- Emulation & calibration tools
Documentation
- Documentation here is key.
- A website that builds itself based on proper, simple and un-redondant information is needed.
Doing and sharing
- Documentation on GitHub and GitBook
- "Blogging" on Hackaday
- A summary on Journal of Open Hardware (thanks GOSH!)
- Tindie for sharing "extra" boards
Issues for "real" medical biohacking and towards medical uses
- Certification
- Sensors sourcing
- Reliability of the device
- Training of users
We can discuss how
- to do a working dev-kit to share knowledge
- implement and efficient (err, lazy) way of documenting.
- share with a community
- better understand your "product"
Other approaches?
- Re-using and improving hardware
- Using old hardware for new approaches
Improving a "rogue" probe
Using differently
