[Castor-users] CASToR v1.1 available

[tmerlin]

Dear users,

A new version of the code is available on the CASToR website : 
http://www.castor-project.org/download_castor

It includes several fixes and bug corrections, in particular for the 
GATE conversion tools (complete changelog in attached files). Besides, 
the GATE SPECThead camera model is now supported in conversion tools 
(see general documentation for the currently supported macro commands).

Kind regards,

Thibaut Merlin

-------------- next part --------------

## New features

- Add SPECT support for GATE tools (root output only)
- '-sens-histo' option that allows to compute the global sensitivity from a histogram datafile
- Add option to specify rotation direction (clockwise/counterclockwise) for PET scanner geometry generation
- Acf estimation in GATE tools : Add option to select the projector for analytic projection
- Add a .geom scanner example for PET in config/scanner (PET_GE_GATE.geom)

## Bug corrections, code changes, that can affect the results in some way

- Changes in Joseph projector to manage more accurately limit conditions at the borders of the image.
  This affect the projector to a small degree, but which can be significant when testing the PET histogram benchmark.
- MPI management bug correction after the sensitivity generation that prevented from proceeding to the reconstruction.
- Bug fix when more threads than events are used (the code was stuck in an infinite loop before that).

## Small bug fixes
- Fix several errors in GATE conversion tools (calculation of several variables and rotation management)
- Fix attenuation image in spect benchmark (incorrect mu values)
- Fix return value of GetGATESystemType() if mac file was not found
- Fix transaxial voxel number and field of view default in PET_CASTOR_BENCHMARK.hscan header file
- Fix decay calculation for isotope with large half-life (i.e Ge-68)
