2. Statement of Intended Use
The patient is not the intended user.
There are no user-serviceable parts inside the Nexus DR system or subsystem components.
Refer all repair needs to a service organization that has been trained and authorized by Varex.
Intended conditions for use, storage, or
transportation
The Nexus DR digital imaging system’s components are sensitive to condensing moisture
and generate some heat. Therefore, the Nexus DR digital imaging system must be installed
in a controlled environment that provides an ambient temperature adequate for cooling and
maintains a humidity level that prevents condensation. When the Nexus DR digital imaging
system is to be transported, all system components should be protected by the original
packaging to reduce the risk of damage in transit. See CHAPTER 5 Power and Environmental
Specifications for specific information.
Operating principle
The essential performance of the Varex imaging system is to synchronize the image
acquisition of the digital receptor with the X-ray beam of the host X-ray system to capture,
display, and archive quality images of the intended anatomy, with reasonable patient exposure
to X-rays.
The Nexus DR digital imaging system uses a solid-state X-ray detector to capture digital
images of anatomy penetrated by an incident X-ray beam. A host X-ray system generates
the X-ray beam, which passes through a patient and strikes the detector the Nexus DR digital
imaging system. The detector converts the X-ray energy to digital image data that is then
passed to the Nexus DR digital imaging system computer. The computer processes the image
data, displays the image to the user, and provides temporary storage for image data and
associated patient information, which can be imported from a worklist or entered manually.
When the user has finished applying processing, annotation, and measurement features
of the Nexus DR digital imaging system software, the images can be archived or printed to
appropriate DICOM-compliant devices.
