Introduction

Magnetic Resonance Imaging (MRI) capitalizes on the quantum properties of matter to emerge as the most versatile medical imaging technique available to date, making it possible to image tissues deep and superficial, soft and hard. The vast number of protons in the human body contribute to high quality images, both in terms of spatial resolution and signal-to-noise ratio. Combined with the possibility of manipulating and detecting the magnetization of protons with electromagnetic radiation in the radio-frequency range of the spectrum, this qualifies MRI as the only medical imaging technique enabling access to deep tissues, in vivo and with high resolution, while avoiding harmful ionizing radiation.

MRI finds use also beyond human and veterinary medicine or biology, and is employed for industrial, engineering and pharmaceutical applications with materials and inanimate objects to study their internal properties or observe their behavior when subject to variable environmental parameters.

Who are we?

The Magnetic Resonance Imaging Laboratory (MRILab) at i3M in Valencia was created in 2014. We are a rather unique blend of quantum and medical physicists and engineers with a focus on two related goals. The first is to boost the quantitative performance of current MRI systems. The second is to exploit the potential arising from the strong synergies between the fields of MRI and Quantum Information Processing (QIP) to advance MRI in directions thus far unfathomed, qualitatively distinct from established trends, and based on algorithms, protocols, techniques and technologies refined in the field of QIP and its most notorious branch, quantum computing.

Projects

Ongoing projects

In situ imaging of living tissues with cellular spatial resolution (Histo-MRI).
Funded by European Commission under the FETOPEN (H2020) program 2016

The main objective of HISTO-MRI project is to develop the technologies that will enable the non-invasive visualization of individual human cells in vivo and in real time, based on a radical
new Magnetic Resonance Imaging concept: Strong Pre-Polarized magnet field and Ultra-High Frequency Pulsed gradient system.

Dental imaging with low-field magnetic resonance imaging (DentMRI)

Funded by ATTRACT and European Commission under the H2020 program 2019

The main goal of the DentMRI project is to demonstrate a technology capable of simultaneous, high resolution imaging of soft and hard deep biological tissues, and which can be massively deployed in dental clinics within the next decade. Prior to the project start, we have been first to obtain high-resolution images of teeth (the hardest tissue present in the human body) in a Magnetic Resonance Imaging (MRI) scanner operating at low magnetic fields. Running at 0.3 T, well below the 1.5 T clinical standard, equipment costs are reduced by one to two orders of magnitude, a necessary condition for commercial viability.

In the scope of DentMRI, we will develop new electromagnetic pulse sequences for a test MRI scanner, as well as an image post-processing software application for diagnostic aid. We will use these to generate the first combined images of teeth and gum with diagnostic value, which will be assessed by professional odontologists. This test setup can accommodate objects of size up to 1 cubic centi-meter, so it is an additional goal of DentMRI to equip a human-head scanner with the radio-frequency electronics required for the pulse.
