Routing is the process where DICOM commands are sent to a combination of target application entity titles [AET]. The reasons for routing vary. For instance, one application may forward all X-ray Angiography [XA] image studies to a departmental archive and all other image modalities to an enterprise archive. The need for DICOM routing varies from facility to facility. In some cases, some department systems or the overall hospital infrastructure may not support specific modalities, in other cases. DICOM routing is needed to effectively manage space availability within the archive system.
