Open Source Imaging Initiative (OSI²) https://cuddly.tube/c/osii/videos The Open Source Imaging Initiative (OSI²) represents a new approach to the development of medical imaging devices, aiming to make the health-care benefits of modern instruments accessible to many more people around the globe. The project will pool the knowledge and experience of many experts in open-source designs for Magnetic Resonance Imaging devices (MRI) which can be built and maintained for a fraction of the price of current instruments.

The presentation was given on 30th of September 2020 at the virtual conference of the European Society for Magnetic Resonance in Medicine (ESMRMB, https://www.esmrmb.org/congress/congress2020/).

Short overview of the topics covered:

  • Current progress in Open Source Soft- and Hardware development of low field MRI scanners
  • First standard on Open Source Hardware
  • Potential cost savings by an Open Source approach for the public healthcare system

We believe Open Source should be the standard in healthcare. In order to reach that, a big milestone has been achieved by assembling OSI² ONE, an MRI scanner that is nearly 100% open source hardware. Here is a short overview of this fantastic project.

The aim of the open source imaging initiative (OSI²) is to address this issue collaboratively by building a quality, affordable open source MR scanner. Combining innovation and open source approaches will generate global value by reproducible science and development and will allow a major reduction of investments and operational costs with the guiding principle: From the community, for the community.
