What is it indicated for?
The IRm is a mobile X-ray system to be used for 2D planar and fluoroscopic and 3D imaging for adult and pediatric patients. It is intended to be used where 2D and 3D information of anatomic structures such as bony anatomy and soft tissue and objects with high X-ray attenuation such as (metallic) implants is required.
The IRm provides an interface that can be used by system integrators for integration of the IRm with image guidance systems such as surgical navigation systems.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
