Project ID : 6-2017-4449
Description of the technology
Diamond, defects, MRI, nitrogen-vacancy
Current development stage
TRL3 - Hypothesis testing and initial POC is demonstrated
- The standard MRI approach requires large magnetic fields, yielding bulky and expensive machines. Moreover, the inductive measurement is limited in terms of sensitivity and resolution.
- These downsides result in limited availability of MRI machines, as well as poor applicability for analyzing small objects (e.g. ovarian status in IVF, gastrointestinal ESD specimens).
- A novel method for measuring MRI signals that relies on a different modality of magnetic sensing:
- High-sensitivity due to the sensor’s proximity to the measured sample, together with an optical readout of the signal, provides orders-of-magnitude higher sensitivity.
- High-resolution – the optical readout of the MR signal allows high-spatial resolution, down to several 10’s of microns.
- Small package – the sensor modality consists of a measurement head of mm-scale, which is therefore portable and cheap, and could be integrated into endoscopic configurations.
- The development addresses medical diagnostic scenarios for currently inaccessible applications
- Hand held MRI has potential to become a portable device with high availability.
- The development serves for further research of miniature nuclear magnetic resonance (NMR)
