Why is the content I wish to access not available via ORA?
Bibliographic data (the information relating to research outputs) and full-text items (e.g. articles, theses, reports, etc.) arrive in ORA from several different sources. Unfortunately we are not able to make available the full-text for every research output.
Please contact the ORA team (

) if you have queries regarding unavailable content OR if you are aware of a full-text copy we can make available.
Content may be unavailable for the following four reasons
-
Version unsuitable
-
We have not obtained a suitable full-text for a given research output. See this page for more information.
-

Clearance
-
Some thesis volumes scanned as part of the digitisation scheme funded by Dr Leonard Polonsky are currently unavailable due to sensitive material or uncleared third-party copyright content. We are attempting to contact authors whose theses are affected.
Alternative access to the full-text

Item Description
- Documentation:
-
The niiT1vfa program enables a fast nonlinear least squares fit for T1 estimation using a robust and efficient version of the Levenberg-Marquardt minimization algorithm provided by a derivative solver in the Gnu Scientific Library (GSL, http://www.gnu.org/software/gsl/). Input data are variable flip angle (VFA) '.nii' data and (optionally) a processed actual flip angle imaging (AFI) 'nii' data set containing the flip angle (FA) distribution resulting from the prescribed AFI flip angle.
