Release of RTK v2.4.1

Dear RTK users,

RTK v2.4.1 has just been released. This release is intended to produce Python packages compatible with the ITK Python packages v5.3rc04.post4. I have also moved the repository to the RTKConsortium organization so please update your git origin (e.g., git remote set-url origin https://github.com/RTKConsortium/RTK.git).

Release notes:

• Update GitHub links to the new RTKConsortium repository,
• Update GitHub actions for compatibility with ITK v5.3rc04.post4,
• Add Python wrapping of DrawQuadricImageFilter.

Release of RTK v2.4.0

Dear RTK users,

RTK v2.4.0 https://github.com/SimonRit/RTK/archive/v2.4.0.zip has just been released. This release is intended to produce Python packages compatible with ITK V5.3rc04.

Release notes:

• New convenience functions ReadGeometry / WriteGeometry,
• New tilt feature in the ImagingRing geometry,
• Improved Forbild projection,
• Several bug fixes and style improvements.

Many thanks to all contributors for this release, in alphabetical order: Andreas Gravgaard Andersen, Antoine Robert, Fernando Hueso-González, Gabriele Belotti, Hans Johnson, Lucas Gandel, Mikhail Polkovnikov, MrTzschr, Shengpeng YU, Simon Rit and Tom Birdsong.

The next release will be a major one which will split the ITKCudaCommon code in a separate ITK module.

Release of RTK v2.3.0

Dear RTK users,

RTK v2.3.0 https://github.com/SimonRit/RTK/archive/v2.3.0.zip has just been released, about nine months after RTK v2.2.0. This release is intended to produce python packages compatible with ITK v5.2.1 (current release on pypi.org). I will soon prepare another release for ITK v5.3 since ITK v5.3rc01 has been released.

Release notes:

• Improvement of Forbild phantom simulation (for head phantom in particular),
• Refactoring of Cuda handling in CMake,
• Fix and wrap attenuated Joseph and Zeng projectors for SPECT reconstruction,
• Various minor fixes for compilation, CI and install.

Many thanks to all contributors for this release, in alphabetical order: Lucas Gandel, Laurent Malka, Antoine Robert, Simon Rit and Tomoyuki Sadakane.

As usual, be aware that we do not focus on releases since we have a public github repository that we aim at keeping stable. I still recommend the use of the master HEAD over releases to enjoy the new RTK developments before their release. Corresponding python packages can now be downloaded from the Github actions. We still have a few on-going projects for which we will use and enhance RTK.
