Indications for Use

The OnePacs System is an image management system intended to provide scaleable DICOM compatible PACS solutions for hospitals and related institutions and sites, which will archive, distribute, retrieve and display images and data from all hospital modalities (such as CR, CT, DR, MR, and other devices) and information systems. This also includes the display of structured reports and mammography images that have been created according to DICOM "For Presentation", and will include standard features and other tools for analyzing mammography images.

Lossy compressed mammographic images and digitized film screen images must not be reviewed for primary diagnosis or image interpretation. For primary diagnosis, post process DICOM "for presentation" images must be used. Mammographic images should only be viewed with a monitor approved by FDA for viewing mammographic images.

Caution: The OnePacs system as deployed for clinical use is a registered/licensed medical device. Educational and Research versions of the OnePacs system are neither intended nor licensed for clinical use, and should only be used as permitted by applicable and governing regulations.

Notice for users within the United States:

Caution: The OnePacs system as deployed for clinical use is For Prescription Use Only (US Regulation 21 CFR 801.109). Federal law restricts this device to sale by or on the order of a physician.
