Local databases to organize DICOM header information are often used in medical image applications and workstations. This page is used to organize information and examples.
History
Bill started a thread on the slicer-devel mailing list about improving dicom parsing performance. This message includes a sample sql database schema as an attachment.
At the CTK meeting, Marco Nolden showed a similar approach has been followed as part of the MITK project using DCMTK to fill an SQLite database.
Example Data
- MITK DICOM Schema
- Dump of example database created with schema above
- File:Dicom-database-examples-2010-03-09.zip
- Lorensen's strawman sqlite DICOM schema
Considerations
- It would be ideal if the database schema was standardized and could be used with any DICOM toolkit (GDCM and/or DCMTK).
- The MITK schema is nice because it uses the standard DICOM field names for the columns, for example PatientsUID, ModalitiesInStudy, etc).
- Eventually we could create an ITK IO Factory plugin reader that an read when given an SQLite filename and a query string that specifies a volume. With something like: "/tmp/dicom.db:SeriesUID=1.2.3...." If the SQL database kept the width, height, and pixel data offset then the files could be read quickly without re-parsing.
- Marco plans to contribute a cleaned up version of the MITK code to the CTK git repository.
- Bill proposes a background DICOM import mechanism.
