Version 21.3.1

Install using conda from https://anaconda.org/ccpi/cil/files?version=21.3.1

21.3.1

• Added matplotlib version dependency to conda recipe
• Fixed TIGRE wrappers for geometry with a virtual detector
• Fixed TIGRE wrappers for cone-beam geometry with tilted rotation axis

Version 21.3.0

Install using conda from https://anaconda.org/ccpi/cil/files?version=21.3.0

v21.3.0

• Accelerated PDHG which handles strong convexity of functions
• TotalVariation Function handles SIRF ImageData
• Simulated datasets and volume added to DataExamples
• TIGRE wrappers for parallel-beam geometry added
• NEXUSWriter and NEXUSReader offer (8bit and 16bit) compression of data
• show2D show_geom now return an object that can be saved with a save method
• GradientOperator can be now used with SIRF DataContainers, both PET and MR
• Add anisotropy in TotalVariation function
• CCPi Regularisation plugin is refactored, only FGP_TV, FGP_dTV, TGV and TNV are exposed. Docstrings and functionality unit tests are added. Tests of the functions are meant to be in the CCPi-Regularisation toolkit itself.
• Add dtype for ImageGeometry, AcquisitionGeometry, VectorGeometry, BlockGeometry
• Fix GradientOperator to handle pseudo 2D CIL geometries
• Created recon module with FBP and FDK using fast filtering library and TIGRE backprojectors
• Added Intel IPP based library for filtering step of FBP
• PDHG memory optimisation
• ScaledFunction memory Optimisation
• The github actions are merged into one action with multiple jobs
• The conda build job uploads an artifact of the build tar.bz file which is later used by the documentation build job - which installs the package into a miniconda environment.
• Documentation pages for recon, astra and cil-plugins are published.

Version 21.2.0

Install using conda from https://anaconda.org/ccpi/cil/files?version=21.2.0

• add version string from git describe
• add CCPi-Regularisation toolkit in unittests
• show_geometry implemented to display AcquisitionGeometry objects, can be imported from
  utilities.display
• CentreOfRotationCorrector.image_sharpness implemented which finds the rotation axis offset by maximising sharpness of a single slice reconstruction
• Renamed CentreOfRotationCorrector.xcorr to CentreOfRotationCorrector.xcorrelation
• Implemented Padder processor

v21.0.0

• Show2D now takes 4D datasets and slice infomation as input
• TIGRE reconstruction package wrapped for cone-beam tomography
• Datacontainers have get_slice method which returns a dataset with a single slice of the data
• Datacontainers have reorder method which reorders the data in memory as requested, or for use with 'astra' or 'tigre'
• Subset method has been deprecated
• AcquisitionData and ImageData enforce requirement for a geometry on creation
• New processors AbsorptionTransmissionConverter and TransmissionAbsorptionConverter to convert between Absorption and Transmission
• Implemented Binner and Slicer processors
• Implemented MaskGenerator and Masker processors

Version 20.11.2

20.11.2

• fixed windows build
• NikonDataReader converts Nikon geometry to CIL geometry from xtekct file including detector and centre-or-rotation offsets
• NexusdataReader supports files written with old versions of NexusDataWriter
