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 blends quantum and medical physicists and engineers with a focus on two related goals. One is to boost the quantitative performance of current MRI systems. The other 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.

PhysioMRI Tech

Rubén Pellicer Guridi, PhD

I did my electrical and electronics engineering studies at the Polytechnic University of Mondragón. I worked for 3 years as industrial engineer designing automatised manufacturing lines at CEGASA, Vitoria. Following this experience in industry, I did my master on biomedical engineering after which I had the opportunity to engage in research on magnetic resonance imaging (MRI) at ETH (Switzerland) and Erasmus University Medical Centre (The Netherlands). Aforementioned experiences made me realise that only a fraction of what MR is capable of is translated to help patients, mainly because of the prohibitive costs of this technology. This realisation inspired me to focus my efforts developing purpose built low-cost & portable MRI devices. With this aim in mind, I did my PhD and a postdoctoral stay at The Centre for Advanced Imaging (Australia). Afterwards I returned to Europe and did a research stay at PTB (Physikalisch – Technische Bundesanstalt) Institute and Charité Hospital (Germany) before finally joining the i3M group and PhysioMRI.

Ongoing projects

Elastography with Acousto-optical techniques and Rapid MAgnetic control of biocompatible nanoParticles (EARMAP)
Funded by Ministry of Science and Innovation under the “Retos de investigación” program 2019

EARMAP is a coordinated project formed by two subprojects. One consists in the development of innovative biocompatible nanoparticles which will be detected acoustically and excited either optically with coherent light and/or magnetically by means of intense, rapidly controlled magnetic fields. The other consists in the development of innovative techniques to image the nanoparticles through tissue-mimicking phantoms, quantitatively evaluate their concentration and, simultaneously, to study the viscoelastic properties of the labeled tissues through ultrasound waves produced by the nanoparticles after being excited. The global objective of the project is to develop a novel molecular elastography technique by combining magneto-motive ultrasound and photoacoustic technologies with the use of nanoparticles with outstanding photoacoustic and magnetic activity.

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.


Featured past projects

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.
