Hand Held MRI Device for Local MRI Measurements

Posted by Yissum - Research Development Company of the Hebrew UniversityResponsive · Innovative Products and Technologies · Israel

Summary of the technology

Cluster10a
alternative method for measuring MRI signals, using NV defects in diamond
Project ID : 6-2017-4449

Description of the technology

Keywords

Diamond, defects, MRI, nitrogen-vacancy

Current development stage

TRL3 - Hypothesis testing and initial POC is demonstrated

Application

  • 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).

Our Innovation

  • 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.

Opportunity

  • 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)
