## Indications for use
The ControlRad® Select Model Z with the Artis zee is indicated to provide fluoroscopic imaging of the patient during diagnostic, surgical, and interventional procedures while reducing patients and clinicians' radiation exposure (Dose Area Product) outside of the ControlRad Select Model Z ’s region of interest (ROI) as compared to Artis zee non-collimated image area. 1 The ControlRad Select Model Z semi-transparent filter should not be used in lieu of the Artis zee’s collimators, as they block the most radiation, but can help physicians balance dose reduction with the need to visualize structures outside the ROI when it is considered clinically advantageous to do so. Clinical applications may include cardiac angiography, neuro-angiography, general angiography, rotational angiography, multipurpose angiography and whole body radiographic/fluoroscopic procedures as well as procedures next to the table for i.e. patient extremities. Additional procedures that can be performed include angiography in the operating room, image guided surgery by X-ray, by image fusion, and by navigation systems. The examination table as an integrated part of the system can be used for X-ray imaging, surgery and interventions. 1 Relative to open Field of View (FOV), the ControlRad Select Model Z reduces at least 85% of the Dose Area Product at 65 kVp and ROI with width and length that are smaller than 1/5 the edge size of the full FOV.
