v0.5.0

Added

• double angle mapping (DAM) B1 mapping option
• option to test ambiguous angle ranges beyond [0,90] and [90,180] degrees for SE/STE B1 mapping (nAmbiguousAngles b1 defaults parameter)
• various B1 input checking
• smoothing and masking options for all appropriate B1 mapping methods

Fixed

• issue #42 (Non-matching filename length can cause AFI B1 calculation crash)
• issue #46 (Toolbox expects SE/STE input sorted by echo and flip angle whereas BIDS sorts by flip angle then echo)
• issue #26 (Possible bug in calculation of B1 maps with SE/STE EPI)
• SE/STE B1 mapping calculation can now no longer select both ambiguous angles for a given SE/STE pair

v0.4.0

Added

• weighted least squares R2* fitting
• cleaner input/output functions for map creation
• several unit tests
• nulling of bright voxels during unified segmentation to improve segmentation of anonymised data

v0.3.0

• QUIQI added
• visual quality control tool added

v0.2.6

fixes:

• Backwards compatibility restored: TR, TE and FA can now again be read from the nifti description field if needed

v0.2.5

• Provides option to remove the small angle approximation when calculating R1 and PD
• Bugfix for reverse phase encoding direction 3D-EPI on Siemens scanners
• Experimental BIDS support

v0.2.4

• added back accidentally removed B1 mapping options

v0.2.3

Allows calculation of B1 maps independently of the rest of the quantitative maps

bugfix release v0.2.2

• fix problem with broken JSON serialisation
• open files read only where possible

bugfix release v0.2.1

fix for issue #6

release-v0.2.0

Fixed

Many small bugs - refer to commits for details...

Added

• DICOM import for Philips data:
  Properly accounts for the rescaling factor for quantitative analysis
  (see Chenevert et al. 2014).

• Tracking Matlab version number in the JSON metadata.

Changed

• MT saturation map file name from *_MT to *_MTsat.
