The SIENET Cosmos is a Picture Archiving and Communication System (PACS) intended to enhance the complete imaging workflow, i.e.

* Manipulating

* Reading

* Reporting

* Viewing

* Communicating / distributing

* Storing / archiving

of radiological softcopy images and

* Storing / archiving of structured (DICOM) reports.

The system is a "software only" solution and is intended to assist the physician in diagnosis or treatment planning.

Therefore SIENET Cosmos supports the following generic imaging workflow:

* Receive scheduled exams from IS at the SIENET Cosmos archiving component SDM

* Provide relevant prior exams and reports (Structured Reports only) to the Modalities and Workplaces

* Receive and store new exams from the Modalities at the SDM

* Prepare images for reading

* Report new images, if required by comparing them with prior exams and reports

- Demonstrate exams at Radiological Demos

* View exams and reports at Workplaces outside Radiology (e.g. Surgery, Intensive Case Unit, wards, external

referring physicians).

Note:

The workstation deployment syngo® Viewing Studio is not intended for primary diagnosis.
