Modules

What are the arduino-like ultrasound module ?

Creating modules to facilitate ultrasound hacking : the principles of the echOmods is to enable a full chain of ultrasound image processing and hardware control.

We have chosen to use a module approach to make sure that each key component inside ultrasound image processing can easily be replaced and compared with another module, while providing logical logic blocks and corresponding interfaces for these modules to communicate. There’s a module for high-voltage pulsing, one for the transducer, one for the analog processing, one for data acquisiton, … and many more!

What images does it give ?

What does it look like?

The modules sit on a breadboard, and communicate through the tracks laying below. The configuration represented below show the Basic dev kit.

and used in a wider context:

A recap of the modules

Name	In	Out
goblin: The aim of this echOmod is to get the signal coming back from a transducer, and to deliver the signal, analogically processed, with all steps accessible to hackers.	<ul><li>ITF-1_GND</li></ul><li>ITF-2_VDD_5V</li></ul><li>ITF-7_GAIN</li></ul><li>ITF-4_RawSig</li></ul><li>ITF-3_ENV</li></ul><li>ITF-18_Raw</li></ul><li>ITF-mET_SMA</li></ul>	<ul><li>ITF-4_RawSig</li></ul><li>ITF-3_ENV_signal_envelope</li></ul><li>ITF-mEG_SPI</li></ul>
