🧠 ClinicalASL v1.0.3 – Enhanced DICOM Support and Robust Pipeline Execution

Official ClinicalASL processing pipeline for quantitative multi-delay ASL MRI data — designed for clinical use, with full PACS compatibility and reporting features.

---

🆕 New in this release (v1.0.3):

• DICOM filtering enhancements:

  • Selective import using SeriesDescription, SOPClassUID, and SeriesNumber
  • Intelligent selection of most recent ASL series per tag (e.g., preACZ, postACZ)

• Improved DICOM handling:

  • Multiframe vs. single-frame DICOM series detection
  • Template-based single-frame DICOM export with pixel scaling
  • Graceful skipping of export for missing template types

• Docker optimizations:

  • Custom build of dcm2niix with JPEG2000 support (OpenJPEG) for decoding PACS-exported ASL data

• Minor fixes & enhancements:

  • Robust error handling and warnings for missing or unsupported DICOM files
  • Better logging and traceability of input/output operations
