const { data } = dcmjs;
const { DicomMessage, DicomMetaDictionary } = data;

const arrayBufferOfDICOM = /** Your DICOM file binary */
const dicomDataInTheCorrectResponseFormat = DicomMessage.readFile(arrayBufferOfDICOM).dict;
const dicomDataInANaturalizedFormat = DicomMetaDictionary.naturalizeDataset(dicomDataInTheCorrectResponseFormat);
