Warning: The Nucleus Image Management System is not approved for use with a browser that has browser extensions enabled, regardless of browser compatibility.

Warning: The visual interpretation of digital images depends on the characteristics of the systems displaying those images. Images may have different visual appearance on different devices. Medical professionals should use medical-grade monitors designed and calibrated for DICOM image viewing.

Warning: Mobile devices are not supported for diagnostic use.

Warning: The Nucleus Image Management System is not intended for diagnostic use with non-supported operating systems or browsers.

Note: Users should also consult operating system and browser manufacturer’s system recommendations. Higher memory and CPU/GPU specifications—beyond those recommended by the manufacturer—may improve viewer performance, especially when viewing large images or multiple images concurrently.

Warning: The Nucleus System exam uploader displays a warning message if you try to use the exam uploader with an incompatible browser. For more information about exam uploads, refer to the Nucleus Image Management User Manual.

Bandwidth Requirements

While there are no minimum internet bandwidth requirements, minimum upload and download bandwidths (per user) are recommended for reasonable exam upload and download times. Higher bandwidths improve upload and download times. Organizations should consider aggregate bandwidth requirements for multiple Nucleus System users.
