- Add our applications to the Antivirus exception list (if needed)
Machine Configuration Details
- Machine should be compatible with DICOM standard.
- After we provide the AE Title, Port Number, and IP Address, the Lab Team should configure this in the machine with the help of machine engineer (This should be configured for RIS/WORKLIST and STORAGE/IMAGES SENDING)
- Capture and share a screenshot of the successful ping/ECHO test.
Storage Considerations
Image Storage
- Format: DICOM standard compliant storage
