• OSI² ONE

  Open-source low-field MRI scanner using a 50 mT permanent magnet, portable at roughly 150 kg, for head and extremity imaging.

• OCRA

  Open-source MRI console built on low-cost Zynq FPGA hardware, providing spectrometer and acquisition control.

• MaRCoS Client

  Graphical and command-line client for the MaRCoS open magnetic resonance control system.

• COSI Measure

  Open-source three-axis measurement system with sub-millimetre precision, used to map magnetic fields for MRI construction.

Computed from shared tags, weighted so a rare tag counts for more than a common one. These are suggestions, not curated relationships.

• echOmodsopen-hardware · imaging

  Open-source ultrasound processing modules and building blocks — analogue front ends, FPGA acquisition and pulser boards for do-it-yourself echography.

• un0rickopen-hardware · imaging

  Compact iCE40 FPGA and Raspberry Pi ultrasound board providing pulse-echo acquisition for imaging and non-destructive testing.

• COSI Transmitmri · open-hardware

  Open-source software and hardware transmission system for magnetic resonance imaging radiofrequency chains.

• LIBREhub.github.iomri · open-hardware

  This is repository for LIBRE hub project web page. We use Jekyll to run our GitHub page.

• MaRCoS Servermri · open-hardware

  Embedded server component of the MaRCoS open magnetic resonance control system, running on the scanner hardware.

• MRI-education-resourcesmagnetic-resonance-imaging · mri

  Resources for learning the principles of magnetic resonance imaging (MRI)

   Described as documentation for building the open source ultra low-field MRI at Utrecht University. 105 stars, last pushed 2025-04-29, hence status maintained rather than active. All three CERN-OHL v2 variants are present in the repository, so all three are recorded; GitHub reports NOASSERTION.
