-------------------------------
General set-up and installation:
-------------------------------
- This version is validated for Geant4 10.1
- The compilation is validated for from gcc4.4 to gcc4.9
- It is no more needed to use system CLHEP. Geant4 embedded version now works (flag GATE_USE_SYSTEM_CLHEP=OFF by default).
Alternatively, users may still use system CLHEP version 2.2.0.4 (put the flag ON).
- To download binary data for benchmark and example folders, set GATE_DOWNLOAD_BENCHMARKS_DATA and GATE_DOWNLOAD_EXAMPLES_DATA
variables to ON.
- For GPU features the CUDA tools are needed (see doc).
----------------------------------------------------------------------------
All information regarding the installation are provided by the documentation:
----------------------------------------------------------------------------
Generic page: http://wiki.opengatecollaboration.org/index.php/InstallationGuideV7.1
Cmake procedure: http://wiki.opengatecollaboration.org/index.php/New_Compilation_ProcedureV7.1
GPU modules: http://wiki.opengatecollaboration.org/index.php/New_Compilation_ProcedureV7.1#GPU_.26_CUDA_tools
-----------------------------
New developments and features:
-----------------------------
- GPU modules for OpticalPET and CT applications. For details, read the user’s guide on the section:
http://wiki.opengatecollaboration.org/index.php/Users_Guide_V7.1:How_to_use_Gate_on_a_GPU
Note: technical limitations of the GPU modules are indicated in the user’s guide.
Read also the examples provided within the GATE sources for understanding the interests and limitations.
- Reader of voxellized sources within GATE have been extended. They now can read 3D images in following formats:
* Interfile (8-bit, 16- or 32-bit Signed and Unsigned, and 32- or 64-bit Real)
* Analyze
* MetaImage (mhd/raw)
For details, read the user’s guide on the section:
http://wiki.opengatecollaboration.org/index.php/Users_Guide_V7.1:Voxelized_Source_and_Phantom#Voxelized_sources
- New options with the General Particle Source (GPS) to define and customize an energy spectrum associated to primary events.
For details, read the user’s guide on the section: http://wiki.opengatecollaboration.org/index.php/Users_Guide_V7.1:Source#Defining_the_energy
- Physic list builder mechanism is available, following the Geant4 approach. For details, read the following section:
http://wiki.opengatecollaboration.org/index.php/Users_Guide_V7.1:Setting_up_the_physics#New_physics_list_mechanism
- DoseActor now uses double precision for computation (so the required memory is doubled).
Outputs are still in float. This should solve precision issues in some situations.
- New fast algorithm to compute dose for low energy gamma beams (lower than 1 MeV), the seTLE (split-exponential Track Length
Estimator), about 105-106 faster than plain Monte-Carlo. See example 10 in the source code and
http://wiki.opengatecollaboration.org/index.php/Users_Guide_V7.1:Readout_parameters_for_Radiotherapy_applications:_Actors#TLE_and_seTLE_.28Track_Length_Estimator.29
- Various bug corrections for the PhaseSpaceActor (store all steps default value to off).
- Various bug fixes and improvements.
