Constructing DICOM dataset

DICOM dataset can be easily constructed by inserting tags into an empty dataset or populating an existing one:

DcmDataset dataset;

dataset.setTagValue("MediaStorageSOPClassUID", "1.2.840.10008.5.1.4.1.1.1");
dataset.setTagValue("MediaStorageSOPInstanceUID", "1.2.3.4.5.6.7");
dataset.setTagValue("StudyInstanceUID", "1.2.3.4.5.6.7.1");
dataset.setTagValue("SeriesInstanceUID", "1.2.3.4.5.6.7.1.1");
dataset.setTagValue("SOPClassUID", "1.2.840.10008.5.1.4.1.1.1");
dataset.setTagValue("SOPInstanceUID", "1.2.3.4.5.6.7");
dataset.setTagValue("PatientId", "BJ750315");
dataset.setTagValue("PatientName", "Brown^John");
dataset.setTagValue("PatientSex", "M");
dataset.setTagValue("PatientBirthDate", QDate(1975, 3, 15));

Another way to populate a dataset is by using modules. Modules are sets of tags grouped logically in a single object:

DcmDataset dataset;

DcmModulePatient patient;

patient.setPatientId("BJ750315");
patient.setPatientName("Brown^John");

dataset.attachModule(patient);
