Importing from DICOM files¶
If you are using linux, or for Windows if you have put
C:\Python27\;C:\Python27\Lib\site-packages;C:\Python27\Scripts
onto
your system path, you should be able to import from the command line:
Radiation Dose Structured Reports¶
openrem_rdsr.py filename.dcm
You can use wildcards to process a number of files at once, ie:
openrem_rdsr.py *.dcm
Radiopharmaceutical Radiation Dose Structured Reports¶
You can use the same import script as for Radiation Dose Structured Reports.
For mammography DICOM images¶
openrem_mg.py filename.dcm
The facility for extracting dose information from mammography DICOM images has been designed and tested with images created with the GE Senographe DS. It has now also been used with the images generated by the following systems:
GE Senographe Essential
Hologic Selenia
Siemens Inspiration
For radiographic DICOM images¶
openrem_dx.py filename.dcm
For PET/NM DICOM images¶
openrem_nm.py filename.dcm
Note that more complete information can be loaded from the RRDSRs if available. For PET images the PET series information can be added to the RRDSR data.
For CT dose summary files from Philips CT scanners¶
openrem_ctphilips.py filename.dcm
This extractor makes use of the information stored in the header data of the Philips Secondary Capture object with a series description of “Dose Info”. The value inserted into “Study description” in the OpenREM database is actually taken from the Protocol field. The value in Study description is inserted into the study level comment field in the database, along with the protocol file name and any “comments on radiation dose”.
For CT dose summary files from older Toshiba CT scanners¶
openrem_cttoshiba.py path_to_files
This extractor is designed to create a DICOM radiation dose structured report
from the information contained in secondary capture dose summary images,
supplemented by data stored in image tags. It requires a folder of DICOM
objects as input (suitable data can be retrieved from a DICOM node using the
qrscu.py
command with the -toshiba
switch - see Query-retrieve using the command line interface).
It creates an initial RDSR from the secondary capture dose summary, and then
tries to enrich this with additional information contained in image tags. The
routine attempts to extract the following information from the image tags and
insert it into the initial RDSR:
Study-level information¶
Study description
Requested procedure description
Software versions
Device serial number
Series-level information¶
Protocol name
Exposure time (per rotation)
kVp
Spiral pitch factor
Nominal total collimation width
Nominal single collimation width
Exposure modulation type
The routine was developed for older Toshiba CT scanners that cannot create RDSR objects themselves. It is known to work with:
Toshiba CX, software version V4.40ER011
Toshiba CXL, software version V4.51ER014
Toshiba CXL, software version V4.86ER008 (this software version can produce RDSR objects directly, but may not populate some fields, such as requested procedure name and study description)
This extractor has also been used successfully on images from a GE LightSpeed Plus scanner, although in this case no supplementary data is extracted from image tags.
