2\. DATA SET DESCRIPTION

#  A. DESCRIPTION, NATURE AND SCALE OF THE DATA COLLECTED

The data generated by the M-CUBE project are related to the collection,
characterization and standardization of calculation codes for measurements,
creation of antennas and to produce various kinds of improved MRI images.

The data will be collected through web interfaces on the intranet website of
the project and will serve to build up a web-based catalogue (the M-CUBE
repository) accessible on the MCUBE public website. Hence, it will help
disseminating worldwide data generated through the project.

#  B. ORIGINS OF COLLECTED DATA

The origins of the collected data are the following:

  1. UNIVERSITE D’AIX-MARSEILLE (AMU) 

  

  

1a) Institut Fresnel

1b) Centre de Résonance Magnétique Biologique et Médicale

  2. COMMISSARIAT A L’ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVES (CEA) 

  

  3. UNIVERSITE CATHOLIQUE DE LOUVAIN (UCL) 

  

  4. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE (CNRS) 

  

  5. UNIVERSITAIR MEDISCH CENTRUM UTRECHT (UMC UTRECHT) 

  

  6. AALTO-KORKEAKOULUSAATIO (AALTO) 

  

  7. SAINT PETERSBURG NATIONAL RESEARCH UNIVERSITY OF INFORMATION TECHNOLOGIES, MECHANICS AND OPTICS (ITMO) 

  

  8. THE AUSTRALIAN NATIONAL UNIVERSITY (ANU) 

  

  9. MULTIWAVE TECHNOLOGIES AG (Multiwave) 

  

  10. MR COILS BV (MR Coils BV) 

  

  

C. TO WHOM CAN THESE DATA BE USEFUL?

The aim of collecting these data is to organise the M-CUBE collection and to
propose a web based catalogue to the scientific communities. It will
constitute a readily accessible repository at the European and world level.

\- **It helps:**

The Scientific community of physicists in accessing high quality data and
tools for improving the next generation of MRI images

The health authorities and doctors in facilitating detection of diseases
thanks to better images

3\. How will the data be created and collected?

Each M-CUBE project partner generates the data which help the creation of new
kind of antenna and which facilitate the radically improvement of spatial and
temporal resolutions of MRI images. These data are collected into a database,
through the M-CUBE website, thanks to formatted forms allowing easy filling
in.

All M-CUBE partners have provided details on what type of data they are going
to generate, to provide a short description of the data, their formats, if
they wish to open these sets of data and how they are going to archive and
preserve them.

The updated sets of data generated by M-CUBE partners are listed below.

4\. DATA SHARING

#  A. DATA SHARING AND DISSEMINATION

The data will be made available worldwide through the M-CUBE Website thanks to
dedicated interfaces that will list the M-CUBE data files available and enable
the users to access all data and place enquiries on data of interest.

Access to the data is not restricted, except for adding and editing
permissions that are restricted to the M-CUBE partners.

The M-CUBE data will be widely open to any user except for intellectual
property reasons and/or unmet quality criteria, and will respect the following
disclosure levels set:

  * Consortium: the data are made available to consortium partners only. 

  

  * Public: the data are listed on the public web interface and any user can place an enquiry about a data of interest. 

  

#  B. DATA REPOSITORY

The data will be deposited on the M-CUBE database through the M-CUBE website
that is hosted on servers of the AMU-Institut Fresnel partner laboratory.

##  C. DATA DISCOVERY

The data generated by the project correspond to the description of the
calculation codes, modelisation results, simulation results, coil
specifications and MRI measures that will be generated by M-CUBE partners,
laboratories and SMEs, in their own infrastructure.

These data are discoverable by the users simply, indirectly by using any web
search engines (e.g: google, yahoo, bing...), or directly by connecting to the
M-CUBE website's internal search engine.

LINK :  _http://www.mcube-project.eu/opendata/_

##  D. REUSING DATA

The data are generated by the all the M-CUBE partners. The collected data are
used by endusers to create their own calculation codes, their own coils and to
improve their own measures.

There is no limitation on the way the data can be reused and practically can
serve as reference, even after the project ends.
