Functional Ultrasound Imaging (fUSI) from scratch

📝 Discussion Summary (Click to expand)

DIY ultrasound hardware and home‑lab experimentation

“I've recently built my own ultrasound machine at home with only the probe being an ebay buy from a previously working machine.” – polishdude20
“Please do! That makes me wonder how hard it would be to make a probe.” – jacquesm
Open‑source and community‑driven ultrasound projects

“That's cool. Ultrasound imaging should be much more broadly available, like household object next to your toothbrush.” – kanzure
“I wonder how OpenWater open-source focused ultrasound stimulation is doing.” – kanzure
Emerging multimodal neuro‑imaging (EEG + fNIRS + fUSI) and future prototypes

“MMW: trimodal EEG+fNIRS+fUSI dry headsets are going to change everything. Each technique has its strengths, and there are already people hacking together trimodal prototypes as we speak.” – bbor
“I never got to invest serious time in this idea…” – bbor (showing interest despite limited personal involvement).

🚀 Project Ideas

A plug‑and‑play open‑source ultrasound probe hardware design plus companion imaging software that turns raw RF data into B‑mode images on a laptop.
Core value: lowers the barrier to entry for DIY ultrasound by providing vetted schematics, firmware, and a user‑friendly UI, letting hobbyists and researchers get imaging results without building everything from scratch.

Key	Value
Target Audience	Hobbyists, makers, academic researchers, educators
Core Feature	USB‑connected probe with open‑source firmware and Qt‑based B‑mode viewer
Tech Stack	STM32/FPGA for beamforming, C++ firmware, Python/Qt (PyQt5) for UI, optional WebGL for web preview
Difficulty	Medium
Monetization	Revenue-ready: kit sales ($199) + optional cloud processing subscription ($9/mo)

HN users crave broader availability: “Ultrasound imaging should be much more broadly available, like household object next to your toothbrush.” – kanzure
Provides a concrete path for the probe‑building enthusiasm shown by polishdude20 and jacquesm.

A modular, dry‑electrode headset that simultaneously records EEG, fNIRS, and fUSI with synchronized streaming and open‑source software for multimodal brain imaging.
Core value: enables researchers and biohackers to experiment with cutting‑edge trimodal neuroimaging without costly proprietary systems.

Key	Value
Target Audience	Neuroscientists, biohackers, university labs, makers
Core Feature	Synchronized triple‑modality acquisition with USB/Bluetooth and real‑time fusion dashboard
Tech Stack	ESP32/nRF52 per modality, Bluetooth LE, Python (MNE, NumPy, SciPy), React/WebGL dashboard
Difficulty	High
Monetization	Revenue-ready: headset kits ($1499) + optional analysis SaaS ($29/mo)

“MMW: trimodal EEG+fNIRS+fUSI dry headsets are going to change everything.” – bbor
Gives the community a tangible platform to build on the excitement expressed in the thread.

A web platform where users upload raw RF ultrasound data from DIY probes and receive processed B‑mode images, measurements, and AI‑assisted annotations.
Core value: turns raw hobbyist data into clinically useful images without needing local GPU expertise or software installation.

Key	Value
Target Audience	DIY ultrasound builders, educators, hobbyists
Core Feature	Upload → automated beamforming + B‑mode generation + measurement tools + optional AI lesion detection
Tech Stack	FastAPI backend, Python/NumPy/CUDA for beamforming, AWS S3 storage, React + TypeScript frontend, TensorRT models for AI
Difficulty	Medium
Monetization	Revenue-ready: freemium (free 100 MB/mo, $9/mo for 5 GB + AI)

DIY builders like polishdude20 need software: “I've gotta get on writing an article about it one day!” implies a desire for shareable results.
Provides a shared utility that could spark discussion and lower the barrier for home‑brew ultrasound projects.
