DCMSeg - error on createBinarySegmentation

[jaas]

Hi all,

I am trying to associate DCMTK with a third-party application to use DICOM Segmentation.

I built DCMTK, added it to the project but when I call the method to create the binary segmentation file using:

Code: Select all

DcmSegmentation *segdoc = NULL;

OFCondition result = DcmSegmentation::createBinarySegmentation(segdoc, inputSize[1], inputSize[0], eq, ident);

With inputSize equal to:

Code: Select all

(itk::Image<short, 3>::SizeType) inputSize = {
  m_Size = ([0] = 640, [1] = 640, [2] = 33)
}

eq:

Code: Select all

(IODGeneralEquipmentModule::EquipmentInfo) eq = {
  m_Manufacturer = (theCString = "Test", theSize = 9, theCapacity = 9)
  m_ManufacturerModelName = (theCString = "0", theSize = 1, theCapacity = 1)
  m_DeviceSerialNumber = (theCString = "GetDicomSeg", theSize = 16, theCapacity = 16)
  m_SoftwareVersions = (theCString = "v1.0.0", theSize = 6, theCapacity = 6)
}

ident:

Code: Select all

        }
      }
    }
  }
}

I get the following result:

Code: Select all

(OFCondition) result = {
  theCondition = (theModule = 1, theCode = 42, theStatus = OF_error, theText = "Invalid Value")
  ownsText = false
}

I would like to know if you might have an idea of what might be causing this, the call is practically the same as what's done in https://github.com/QIICR/dcmqi

Thank you for your time.

Best,
Joao

Hi,

you have to fill in all values on the equipment struct, right now Manufacturer's Model Name is empty.

I will add a related hint in the API documentation of the create... methods.

Best regards,
Michael
