orthanc (development version)

New features

  • orthanc has gained support for exporting of NIfTI files for Instances and Series (retrieve_and_write_nifti()), if the Orthanc Neuroimaging plugin is available, and ZIP Archives for Series, Studies, and Patients.
  • Major refactor of resource download methods so that output formats aren’t ambiguous across the various resource types:
    • Instances now have $download_dicom() (formerly $download()), $download_nifti() (only works if Orthanc Neuroimaging plugin is avialable), and $download_image() (if R packages png or jpeg are installed).
    • Series now have download_archive() (formerly download()) and download_nifti() (only works if Orthanc Neuroimaging plugin is avialable).
    • Studies now have download_archive() (formerly download())
    • Patients now have download_archive() (formerly download())

    • Instances now have:
      • download_dicom(): Download DICOM file to a path

Minor improvements and bug fixes

  • Improved support for progress bars and parallelization for find_and_filter().

  • Instance$download_nifti() and Series$download_nifti() now use gzip compression by default.

  • $image_orientation_patient() and $image_position_patient() now return parsed numeric vectors instead of character vectors.

  • All $date or $*_date fields now return "Date" class vectors instead of character vectors.

  • $file_size now returns “pretty” units thanks to prettyunits::pretty_bytes().

  • Updated $print() method for resources to show locked state, if locked.

  • Added new $is_locked field to check whether child resources are locked or not.

    • This active binding can be used to modify locked state through assignment.
