Getting usable images with a 500$ DIY ultrasound machine

Another couple of hours worth of playing - full lab log on github (Session 6) !

We finally get some images from the fantoms (that is, condoms filled with agar gel and tapioca balls).. and below is the setup, upper left the clinical image (coming from a 100k$ machine) and our image (lower). We clearly see the bigger tapioca balls (orange circles) and smaller (blue marks).

Mission accomplished =)

Same type of config, from a different angle: seeing low diffusion areas =)

Last but not least, the noise (circled in red) is due to the bitscope itself, I'm getting a USB isolator to get rid of this damn noise.

Hey Jan, just posted new images, less noise, and a scale :)

  Are you sure? yes | no

Thats purely amazing progress! Keep up the good work!
Just curious: Is the image resolution tied to the sensor/hardware or can we expect
images with higher resolution soon?

  Are you sure? yes | no

Many thanks for your comment Jan !
The sensor we're using is not perfect, and we have a really cheap servo.. However, as a first step, the resolution could be made better with another algorithm to improve the spatial resolution in the lower part of the image. There are raw data files, and a python framework.. would you be up for the challenge? :)

With this two, I'm curious to see what are going to be the next generation of images!
