Added

  • ct_index, mr_index, pt_index tables (idc-index 0.12.3 / idc-index-data 24.2.0): modality-specific acquisition and reconstruction parameter indices, one row per series, all joining on SeriesInstanceUID
    • ct_index (21 columns): pixel spacing, slice thickness, kVp, convolution kernel, tube current min/max (dose-modulated), exposure, spiral pitch, scan options
    • mr_index (22 columns): field strength, scanning sequence, TE (array for multi-echo), TR, flip angle, DiffusionBValue (array for DWI), pixel bandwidth, receive coil, number of temporal positions
    • pt_index (21 columns): radionuclide, injected dose, reconstruction method, decay/scatter/attenuation correction, frame duration (array for dynamic PET), number of time slices
  • SQL query patterns for all three new tables in references/sql_patterns.md
  • Join column entries for ct_index, mr_index, pt_index in references/index_tables_guide.md and SKILL.md
  • Parquet file entries for ct_index.parquet, mr_index.parquet, pt_index.parquet in references/parquet_access_guide.md

Changed

  • Added concrete indices_overview code example showing how to search for a column across all tables and read column schemas without fetching the table; directly addresses the failure mode where agents query index for modality-specific parameters (SliceThickness, KVP, etc.) instead of using ct_index/mr_index/pt_index
  • Added troubleshooting entry "Column not found in index table" with a working indices_overview search snippet and join example, covering common acquisition/reconstruction parameters that live in the modality-specific index tables
  • Updated idc-index reference to 0.12.3
  • Clarified download_from_selection API: added explicit warning that it takes filter keyword arguments (not a DataFrame), comparison table vs download_dicom_series (which has a different first-argument order), and restructured the download example as a step-by-step query → extract UIDs → pass list flow
  • Documented download_dicom_series as an alternative download method with its own signature (seriesInstanceUID as first arg, then downloadDir)
  • Reduced redundancy and duplication in SKILL.md for cleaner reading
