CCP SyneRBI SIRF

v3.1.0

• MR/Gadgetron

  • Golden-angle radial phase encoding (RPE) trajectory is supported if Gadgetron toolboxes were found during building<br /> WARNING if Gadgetron was compiled with CUDA support, you need to build SIRF with the Gadgetron_USE_CUDA CMake variable set to ON.
  • Automatic calling of sort_by_time() in most places. This ensures that only consistent images are reconstructed.
  • Encoding classes perform the Fourier transformations instead of the MRAcquisitionModel
  • CoilSensitivitiesVector class now has forward and backward method using the encoding classes getting rid of the duplicate FFT code used to compute coil sensitivities from MRAcquisitionData.
  • Added constructor for GadgetronImagesVector from MRAcquisitionData. This allows setting up an MR acquisition model without having to perform a reconstruction first.

• PET/STIR

  • iterative reconstructors set_current_estimate and get_current_estimate now create a clone to avoid surprising modifications of arguments. The old behaviour of set_current_estimate can still be achieved by set_estimate.<br> Warning This is backwards incompatible, but arguably a bug fix.

• SIRF Python interface

  • range_geometry and domain_geometry methods of AcquisitionModel classes, required by CIL algorithms, now obtain data via respective C++ AcquisitionModel classes accessors, in line with our strategy of keeping interface code minimal
  • sirf.Gadgetron.AcquisitionData.get_info was renamed to get_ISMRMRD_info to avoid confusion with the other get_info() methods that return a string. (get_info still works but issues a deprecation warning).
• Build system
  • fix bug with older CMake (pre-3.12?) that the Python interface was not built #939.
