| bchintada | Thank you 5M5PLH9S. Congratulations on the versatile US board that you made! I am here to digest the information of different US board designs and the discussions around. Sure!
I am looking forward to learning and contributing. | 16:55:39 |

| brewster.joshua1 | Hey everyone, I'm a hardware & software designer doing low cost FNIRS and EEG, would love to dive into ultrasound. | 17:14:45 |
| brewster.joshua1 | I can help with scalability too but ultrasound still can't be done as cheap as those. | 17:15:35 |
 adamsonjesse | Hey Josh, cool deal and welcome. I'm a power electronics engineer in Seattle. I joined the group a few months ago to learn about ultrasound and photoacoustics. FNIRS and EEG look pretty cool, I also was interested in learning how the infrared measurements of hemoglobin work and if we could measure other molecules in the blood too. | 23:06:32 |

 mhough | Hey 028M4FEK8Q, I lead the NeuroTechX chapter in San Francisco and it is how I first met 02PANQKS0H | 03:27:15 |
| mhough | We are kind of lucky that not much else absorbs at least at the same frequency or we would need to know the mixture proportions | 03:30:32 |
| mhough | Check out https://openfnirs.org for more information about the instrumentation and what is being measured | 03:33:48 |
| mhough | And feel free to join us Thursday evenings 6-9pm https://www.meetup.com/NeuroTechSF/ | 03:34:58 |
| adamsonjesse | Oh wow that looks really cool. Ok I signed up for the meetup so I can check it out sometime. One thing I was looking into was measuring blood cholesterol, but it definitely looks more complicated than hemoglobin. | 22:16:33 |

 kelu | A bit late but welcome 02PANQKS0H and happy to see you're already connecting 😃 | 08:28:05 |

| kelu | You may have seen this for multi array probes : https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=9281323 .. but the cost of the chips is ... not cheap 😉 | 21:38:09 |

| kelu | Interesting technique to cast PDMS-embedded piezos 😃 | 08:47:07 |

| kelu | Welcome here 02SZ48C3M2 ! I trust you have an interest in https://www.nature.com/articles/s41746-020-0240-8 -- so have 6E49CNV6 and GJ8GJGNR to cite only them 😃 | 21:00:33 |
|  raphael.hotter joined the room. | 21:08:11 |
| raphael.hotter | Thanks 5M5PLH9S! Yes, I've been exploring reproducing the work and setting up benchmarks for ultrasound neuroimaging | 21:08:11 |
| raphael.hotter | I'd be excited to talk with others who are also interested in ultrasound neuroimaging! | 21:09:05 |
| kelu | Very cool! What hardware have you been using? I've seen some videos online 😃 | 21:23:53 |
| 7 Jan 2022 |
| raphael.hotter | Just simulations for now | 16:33:53 |
| mhough | Hi 02SZ48C3M2, super interesting! I’d love to know how you are doing your simulations. I know Jean is doing other things now but GJ8GJGNR made an OpenEIT kit/software https://github.com/OpenEIT for doing electrical impedance tomography in 2D and the we developed Fijee https://github.com/Fijee-Project/Fijee to do FEM skull impedance tomography (conductivity scanning) a long time ago now. I would recommend the SimNIBS project for doing brain/physics simulations https://simnibs.github.io/simnibs/build/html/index.html. I would love to be able to do the ultrasound brain simulations they are doing in the FWI paper. | 20:03:43 |

 jean.rintoul | The full wave inversion stuff is pretty cool as a new form of imaging. | 20:31:14 |
| mhough | https://www.sciencedirect.com/science/article/pii/S2352711021001849 | 21:20:55 |
| mhough | I feel like Physics Informed NNs (PINNs) would also be very efficient computationally. | 21:25:19 |
| kelu | Plugged in a shameless ad - thanks for sharing 😃 | 21:26:24 |
| mhough | But as I understand it the “trick” with FWI in seismology is having a computational model of the physics of the area of interest - in other words a FEM of the head | 21:27:07 |
