The modality worklist is a DICOM process for identifying patients who are scheduled for a study. The Workflow Engine retrieves this patient schedule on a regular basis and applies a range of filters. These filters select or remove patients according to specific facility or departmental needs. For example, the SilverBack Workflow Engine can apply a filter that excludes all patients who are not scheduled for a procedure in a specified department. With this feature, the modality worklist can identify ONLY the patients who are scheduled for a specific procedure within a specific department.
