Added

  • volume_geometry_index table documentation: 3D geometry validation for single-frame CT, MR, and PT series; boolean checks (orientation, spacing, dimensions, slice positions) and composite regularly_spaced_3d_volume flag; join via SeriesInstanceUID
  • rtstruct_index table documentation: RT Structure Set metadata (total ROIs, ROI names, generation algorithms, interpreted types, referenced image series UID); join via SeriesInstanceUID
  • New reference guide references/parquet_access_guide.md: direct DuckDB queries against public GCS Parquet files without installing idc-index; URL pattern, available files, and query examples for main index, volume_geometry_index, and rtstruct_index
  • SQL patterns for volume_geometry_index and rtstruct_index in references/sql_patterns.md
  • Detailed documentation for BigQuery-only derived tables in references/bigquery_guide.md:
    • segmentations: per-segment anatomy with full schema, column descriptions, and queries for discovering structures, filtering by coded concept, and linking to SR measurements; note on gap vs seg_index in idc-index
    • quantitative_measurements: radiomics and clinical numeric measurements from DICOM SR TID1500 (volume, diameter, shape descriptors, texture, intensity statistics); full schema with column descriptions and query examples
    • qualitative_measurements: coded assessments from DICOM SR TID1500 (malignancy rating, calcification, texture, margin); full schema with column descriptions and query examples
    • measurement_groups: parent grouping table for SR measurements
    • Combined example joining all three derived tables for LIDC-IDRI nodule analysis (malignancy + volume + diameter)
  • SKILL.md section 7 now explicitly lists per-segment anatomy search, quantitative SR measurements, and qualitative SR measurements as BigQuery-only use cases with no idc-index equivalent

Changed

  • Updated to idc-index 0.11.14 (idc-index-data 23.10.1)
  • Added SOPClassUID and TransferSyntaxUID columns to Key Columns Reference in references/index_tables_guide.md
  • Added Direct Parquet Access entry to Data Access Options table and pointer in SKILL.md
  • Added parquet_access_guide.md to Quick Navigation table in SKILL.md
