[vtkusers]information in DICOM image

[m26404030 at john.petra.ac.id]

I have tried to use vtkMedicalImageReader2 to read my medical image data but
I couldn't get any information i needed.

This is my code

void main()
{
	vtkMedicalImageReader2 *reader=vtkMedicalImageReader2::New();
	reader->SetFileName("IM2.dcm");
	reader->Update();

	printf("%s",reader->GetMedicalImageProperties()->GetPatientName());
	printf("%s",reader->GetMedicalImageProperties()->GetPatientSex());
	printf("%s",reader->GetMedicalImageProperties()->GetPatientBirthDate());
	printf("%s",reader->GetMedicalImageProperties()->GetImageNumber());
	printf("%s",reader->GetMedicalImageProperties()->GetSeriesNumber());
}

all of these functions such as GetPatientName(),GetPatientSex(), etc return null
value.
I dont know why..
Can someone give some examples how to use vtkMedicalImageReader2?


Thanx a lot :-)
