DICOM-Atlas

An open registry of public and private DICOM tags.

DICOM-Atlas compiles tag entries from vendor conformance statements plus the PS3.6 public dictionary, with additional contributions from pydicom and GDCM, into a single frozen memory-mapped archive (tags.dmap). The archive is queryable in O(log n) with no runtime allocations from Rust, C, or Python.

What you get​

  • 19,521 tags in a single 3.9 MB file.
  • 5,128 PDF-verified private tags scraped from 1,840 vendor conformance PDFs (Siemens, GE, Philips, Canon, Acuson).
  • 9,432 community-contributed private tags from pydicom / GDCM.
  • 5,129 public tags from the PS3.6 standard.
  • A single-binary dicom-lookup CLI.
  • A dicom-map Rust crate, C FFI (dicom-map-ffi), and Python package (dicom-map on PyPI).

Why​

Most DICOM toolkits ship only the public dictionary. Vendor private blocks - which carry the truly interesting per-scanner metadata - are spread across thousands of pages of PDF. DICOM-Atlas turns that haystack into a single hash-lookup.

Status​

The registry is research / reference data. It is not validated for diagnostic use. Tag entries may contain errors, especially for older or hand-transcribed vendor blocks; please open issues with citations if you find one.
