dicom-faker
Generates random dicom headers.
Right this, this is super basic.. it only randomizes following fields
- Various UID (SOPInstanceUID, SeriesInstanceUID, StudyInstanceUID, etc..)
- Various Patient information (name, sex, weight, etc..)
- Various Dates (Study Date, time, SeriesDate, time, etc..)
- WindowCenter
- WindowWidth
- RescaleSlope
- LargestImagePixelValue
- (A few others..)
In the future, I want to be able to specify modality, or Manufacturer and generate more realistic data (Help welcomed - especially sample headers!)
Another major todo is that, it currently uses uuid for various dicom IDs generated. I need to come up with some library that can parse / generate dicom UIDs. If you know how to do this, please let me know also.
Installation
npm install dicom-faker -gUsage
To generate a random instance using built in template, just run
dicom-fakerOr you can use your own template to generate another instance by adding "instance" followed by the path for your template.
dicom-faker instance my_template.jsonIf you want to create a whole new series, use "series" option.
dicom-faker series my_template.jsonOr if you want to create a new study
dicom-faker study my_template.jsonOr
dicom-faker patient my_template.jsonDicoms images are usually organized in following hierarchy
patient > study > series > instance
Basically, if you specify "series", it randomizes fields for series and instance. If you specify "study", then it randommizes study, series, instance., If you specify "patient", it randomizes all fields that dicom-faker can randomize.
