VOXEL - Volumetric medical X-ray imaging at extremely low dose
Computerized Tomography (CT) has been one of the greatest achievements in medical imaging, but at the cost of a high, potentially harmful, X-ray irradiation dose. The ultimate goal of VOXEL is to provide an alternative to tomography with a disruptive technology enabling 3D X-ray imaging at very low dose. VOXEL aims at prototyping new cameras working either in the soft or hard X-rays that will combine the X-ray penetration and nanometre spatial resolution, easiness to use, afforded by avoiding the rotation of the source or the sample, and extremely low dose for maximum impact on medicine and biology.
VOXEL relies on the integration of trans-disciplinary fields in medical imaging, optics, X-ray physics, computational and applied mathematics. The VOXEL team members are experts in X-ray metrology, wavefront sensing, atomic physic, mathematical computing and 3D medical imaging. By basing the research lead in Portugal with a woman coordinator, VOXEL will be transformative for scientifically emerging countries.
VOXEL is an international project, with partners from Portugal, Spain, France, Italy, and the Netherlands. You can find a short description of all the VOXEL partners below.

The new VOXEL metrology station is ONJanuary 5, 2017
Around the beginning of 2017, IPFN received a new laser for the VOXEL program (Volumetric medical X-ray imaging at extremely low dose), thanks to the support of the European Commission under the program Horizon2020. The new laser will create an ultra-short and ultra-intense infrared light source, which focused on gases and solid targets like metals, creates x-rays to test the VOXEL camera. These tests will be crucial to calibrate the VOXEL camera prototype.
In a more technical basis, the GoLP team currently has a dual 800 nm laser providing 25 mJ - 40 fs - 10Hz and 7.5 mJ - 30 fs - 1kHz beams on a daily basis. With this configuration, the team hopes to build the X-ray beam lines, which will result toward nice experimental results.
As PI of the GoLP division of the VOXEL program, Marta Fajardo thanked all the involved in the effort, and welcomed all interested in booking a tour to the new facilities.
Virtual unrolling and deciphering of Herculaneum papyri by X-ray phase-contrast tomographyOctober 24, 2016
More than 1800 carbonized Greek and Latin papyri, discovered atÂ Herculaneum in 18th century, form the unique library survivedÂ from antiquity. This unique collection was charred during 79Â A.D. Vesuvius eruption, a circumstance which providentially preservedÂ them until now. The goal is to read the text hidden insideÂ unopened papyrus rolls without damaging them. We succeeded in reading the largest portion of Greek text everÂ detected inside Herculaneum-papyrus rolls using X-ray phase-contrastÂ tomography combined with a set of numerical algorithms forÂ â€˜virtual-unrollingâ€™. We obtained precious information on theirÂ probable author, content, ink and on unexpected events historicallyÂ experienced by them.
The work has been published in Scientific Reports 6, articleÂ number:Â 27227 (2016). The results have had an eco on the media, namely in italian news broadcast and in CNN, which filmed the presentation of this work during the 28th International Congress of Papyrology, (1-6 august 2016 Barcelona, Spain) and is preparing a report to be aired in November 2016.
