Intended Use

The ControlRad® Select Model Z with Siemens Artis zee is indicated to provide fluoroscopic imaging of the patient during diagnostic, surgical, and interventional procedures while reducing patients' radiation exposure (Dose Area Product) outside of the ControlRad Select Model Z's region of interest (ROI) as compared to Artis zee noncollimated 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, rotational angiography, multipurpose angography and whole body radiographic/fluoroscopic procedures as well as procedures next to the 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 Xray imaging, surgery and interventions.

Device Story

ControlRad Select Model Z, Trace Model 9, and Trace Model 8 are add-on systems for existing fluoroscopic X-ray units (Siemens Artis zee, OEC 9900 Elite, OEC 9800 Plus). Components include a semi-transparent titanium filter mounted on the system collimator, a tablet for clinician control, and hardware/software modules. Clinicians use the tablet to define a region of interest (ROI) on the live X-ray image. The system adjusts the filter to reduce radiation dose in the periphery (outside the ROI) while maintaining full-dose imaging within the ROI. This provides peripheral context while lowering overall radiation exposure to patients and the clinical team. The device operates in parallel to the host X-ray system; it does not modify the host's primary imaging FOV or collimator functionality. The system is intended for use by trained clinicians in clinical settings like ORs and interventional suites. It benefits patients and staff by reducing cumulative radiation dose without compromising diagnostic image quality within the ROI.

Clinical Evidence

Bench testing only. Evaluations included Air Kerma/Air Kerma Rate accuracy, Dose Area Product (DAP) accuracy (±35%), DAP reduction verification (at least 50-85% reduction depending on model), filter attenuation (44-98%), mechanical reliability, collision sensor functionality, and image quality comparisons (inside vs. outside ROI). Clinical simulations validated image context utility. Usability testing per IEC 60601-1-6 confirmed safe operation.

Technological Characteristics

Components: Titanium semi-transparent filter (2.5mm or 3.0mm), tablet GUI, hardware/firmware modules, communication interface. Connectivity: Networked/integrated with host X-ray system. Energy: X-ray modulation via filter. Standards: ISO 14971, IEC 60601-1, IEC 60601-1-2, IEC 60601-1-3, IEC 60601-1-6, IEC 62304, IEC 60601-2-43, IEC 60601-2-54, 21 CFR 1020.30-32.

Indications for Use

Indicated for patients undergoing diagnostic, surgical, and interventional fluoroscopic procedures (e.g., cardiac, neuro, vascular, orthopedic, endoscopic, urologic, critical care, emergency room) requiring X-ray imaging. Used to reduce radiation exposure outside a clinician-selected region of interest (ROI).

### ControlRad® Select Model Z Device Description

The ControlRad® Select Model Z is a set of components mounted on the Artis zee system and cannot be used independent of the Artis zee system.

The ControlRad® Select Model Z consists of a ControlRad filter mounted onto the Siemens Medical Artis zee (K181407) C-arm. The ControlRad filter is installed semi- permanently (i.e., the filter may be removed to return the C-arm to its original condition) to aid in reducing both patient and clinicians' radiation exposure while providing fluoroscopic imaging of the patient during diagnostic, surqical and interventional procedures. ControlRad® hereby submits this Bundled Special 510(k) "Catch-Up" to request clearance to market the ControlRad® Select Model Z with SW version v3.0.1 and a dose reduction claim: 85% of the Dose Area Product (DAP) at 65 kVp with width and length that are smaller than 1/5 the edge size of the full Field Of View (FOV).

The ControlRad Filter is an optional component installed on the Siemens Artis zee's collimator to further reduce radiation emissions. The ControlRad Select Model Z is only compatible with the 20x20 detector and associated collimator. Use of this system on other sizes is prohibited.

Image /page/8/Picture/0 description: The image shows the logo for ControlRad. The word "CONTROL" is in a dark teal sans-serif font, followed by "RAD" in a lighter green color. To the right of the text is a circular graphic with a gradient from dark teal to light green, partially surrounding the "RAD" text.

### ControlRad® Select Model Z Device Description

The additional radiation reduction provided by the ControlRad Filter will be outside the clinician-selected ROI and within the un-collimated region/image FOV.

The main components of the ControlRad® Select Model Z which are used with the Artis zee are:

- ControlRad Tablet
- . ControlRad Filter
- . ControlRad Hardware
- . ControlRad Software and Firmware Modules
- . ControlRad Communication Interface

The ControlRad® Select Model Z is a system used to assist trained clinicians which is used to provide Xrav images when the clinician performs a medical procedure the patients and clinicians' radiation exposure (Dose Area Product) outside of the ControlRad® Select Model Z's region of interest (ROI) as compared to the Artis zee non-collimated image area. The ControlRad® Select Model Z can help physicians balance dose reduction with the need to visualize structures outside the ROI when it is considered clinically advantageous to do so.

ControlRad® Select Model Z contains a titanium filter. Two filter sizes are available with nominal thicknesses of 2.5mm or 3mm. both of which are partially transparent to X-ray radiation.

Based on the user selection of the Artis zee collimator the ControlRad Filter region of interest (ROI) the radiation will be reduced. The X-ray beam inside the ROL is not impacted by the ControlRad Filters. All radiation outside the ROI and inside the Artis zee collimated area will be filtered. This can help physicians balance dose reduction with the need to visualize structures outside the ROI when it is considered clinically advantageous to do so.

The ControlRad® Select Model Z allows physicians to select a customizable region of interest (ROI) using a ControlRad dedicated screen Tablet. The proprietary technology then adjusts semi-tranium filters to deliver the designed high-quality image. This allows the Artis zee to generate an image in the selected physician's ROI while providing a lower radiation dose to the periphery. The result is a reduction in the overall radiation dose and exposure to the healthcare team while providing the physician the contextual information needed outside the ROI.

The workflow is therefore supported with lower radiation than with conventional imaging settings. The ControlRad Filter is designed to always include the center of the ROI. Therefore, when selecting an ROI by the user, the actual ROI might be expanded to include the center of the FOV.

The ControlRad® Select Model Z is a product that can be mounted only on the following configurations of the Artis zee: floor, ceiling, and bi-plane systems.

#### Technological Characteristics:

The ControlRad® Select Model Z consists of the following main components: ControlRad Filter, ControlRad Hardware, ControlRad Software and Firmware Modules and ControlRadion Interface all installed on the Siemens Artis zee. The ControlRad® Select Model Z components are installed semi-permanently on the cleared Siemens Artis zee (K181407) and operate in parallel to the Siemens Artis zee. The removal of the ControlRad® components will restore the device to OEM specifications.

The ControlRad® Select Model Z components provide the following functionalities:

- The CR Tablet provides the user operational control of the ControlRad Select Model Z device via a Graphical User Interface ("GUI"). The CR Tablet enables the clinician to select a Region of Interest ("ROI") on the image displayed on the CR Tablet, which is the same image that is displayed on the Siemens Artis zee's live monitor.

### ControlRad® Select Model Z Device Description

- The CR Filter is installed on top of the Artis zee's collimator. The CR Filter does not affect or modify the functionality of the collimator. The CR Filter is a semi- transparent filter which reduces the Xray radiation outside the clinician-selected ROI typically by 44% to 98%. The actual dose reduction achieved will depend upon specific imaging parameters such as Siemens collimator settings, the kVp and the percentage of the non-collimated image covered by the ControlRad Filter.
- · The ControlRad Hardware, Software and Firmware Modules control the ControlRad Filter positioning, which is determined by the location of the clinician-selected ROI and perform image processing.
- · The ControlRad Communication Interface provides communication between the various components of the ControlRad® Select Model Z and the Artis zee.

#### Principles of Operation:

The Siemens Artis zee provides an image whose boundaries are defined by the Siemens'collimator, i.e., the image FOV is defined by the Siemens non-collimated region. The image FOV size is not affected or modified by the ControlRad® Select Model Z.

Within the Siemens Artis zee non-collimated image region, when using a clinician selected Region of Interest ("ROI") on the ControlRad Tablet, the ControlRad Filters reduce radiation exposure outside the ROI. The resulting image has two parts:

- The image inside the clinician-selected ROI (unfiltered radiation area in the FOV),which has at least the same image quality in the ROI as the Siemens Artis zee (K181407).
- The image outside the clinician-selected ROI (filtered radiation area in the FOV), alower-dose processed image which provides peripheral image context to the ROI.

The Siemens Artis zee's collimator, when used, also reduces radiation emission. However, that collimator reduces radiation emission by blocking the delivery of radiationto the area covered by the collimator. As a result, the Siemens Artis zee's image FOV is limited to the non-collimated region. The ControlRad Filter can be used along with the Siemens Artis zee's collimator to further reduce radiation emissions, and the additional radiation reduction provided by the ControlRad Filter will be outside the clinician-selected RO1 and within the un-collimated region/image FOV. The clinician has the option not to use the CR Filter. In this case, the Siemens Artis zee operates as if the CR Filter was not present.
