Intended Use

The AIRO® is intended to be used for X-ray computed tomography applications for anatomy that can be imaged in the 107cm aperture excluding pediatric patients and patients weighing over 400 lbs (182 kg). Airo is contraindicated as the principal means of guidance during invasive procedures when real-time imaging is needed (e.g., CT Fluoroscopy procedures). In addition, the physician must verify navigation accuracy using an adequate verification method when used with Navigation Systems during surgical procedures.

Device Story

Mobile intraoperative CT system; 107cm bore; 51.2cm FOV. Inputs: X-ray irradiation of patient anatomy. Transformation: Rotating gantry with solid-state X-ray generator and CdWO4/photodiode detector array; data acquisition system; reconstruction computer using filtered-back projection algorithms. Outputs: CT images for clinical review. Used in OR, ICU, ED, clinic, or radiology by physicians/technicians. Features motorized base, battery power, and retractable casters for mobility. Includes sequential axial/helical scanning, tube current modulation, and metal artifact reduction. Output assists clinicians in diagnostic imaging and surgical planning/navigation. Benefits: Intraoperative imaging capability without moving patient to fixed radiology suite.

Clinical Evidence

Bench testing only. Evidence includes risk analysis, design verification, software unit/system integration testing, image quality metrics using phantoms, and offline reconstruction clinical image comparisons for the metal artifact reduction feature. No clinical trials were conducted.

Technological Characteristics

Mobile CT system; 107cm aperture; 51.2cm FOV. Detector: Solid-state CdWO4 scintillator array (32x16 pixels). X-ray source: Rotating anode, liquid-cooled (water/propylene glycol). Power: LiFePO4 battery system. Connectivity: PACS/DICOM 3.0. Software: Windows-based, filtered-back projection reconstruction. Safety: Emergency stop, X-ray indicators, interlocks, patient alignment lasers. Standards: IEC 60601-1, 60601-1-2, 60601-1-3, 60601-2-44, 62366, 60825-1, 62133, UL 1642.

Indications for Use

Indicated for X-ray computed tomography imaging of anatomy within a 107cm aperture. Excludes pediatric patients and patients weighing >400 lbs (182 kg). Contraindicated for use as primary guidance during invasive procedures requiring real-time imaging (e.g., CT Fluoroscopy).

Proprietary or Trade Name: AIRO® Computed Tomography (CT) X-ray System Classification Name: Computed Tomography X-ray System Product Code: 90 JAK Device Classification: Class II Regulation Number: 21 CFR 892.1750

# 3. Predicate Device(s):

The legally marketed device to which substantial equivalence is being claimed is as follows:

- . Airo Mobile CT System – Premarket Notification K131431 (cleared on September 26, 2013, product code 90 JAK)
# 4. Device Description:

The Mobius Airo is a Mobile Intraoperative Computed Tomography (CT) System. The Airo has a large-diameter bore designed for intraoperative use; the main features include a 107cm bore, with a 51.2cm field of view (FOV). The Airo has two modes of operation; transport and scanning (both helical and axial in patient mode). In its scanning mode, translation along the longitudinal axis is achieved through movement of the gantry along the length of the system base (rather than through movement of the patient support table).

{4}------------------------------------------------

The lightweight translating gantry consists of a rotating disk with a solid state x-ray generator, solid state detector array (that includes detector modules that consist of a layered Cadmium Tungstate (CdWO4) and Photodiode Array). Each detector module includes a 32 x 16 pixel scintillator array that produces scintillation events responsive to irradiation by X-rays. The Airo also includes a collimator, control computer, communications link, data acquisition system, reconstruction computer, power system, brushless DC servo drive system (disk rotation), and a DC brushless servo drive system (translation).

The power system consists of batteries which provide system power while unplugged from a standard power outlet (e.g., during transport of the System and also during scanning). The base has retractable rotating caster wheels and electrical drive system can be easily moved to different locations.

In addition, the System has the necessary safety features such as emergency stop button, X-ray indicators, interlocks, patient alignment lasers, and 110 percent X-ray timer. The software helical and axial reconstruction algorithms are both based on an exact filtered-back projection.

### 5. Indications for Use:

The AIRO® is intended to be used for X-ray computed tomography applications for anatomy that can be imaged in the 107cm aperture excluding pediatric patients weighing over 400 lbs (182 kg).

## Contraindications:

AIRO is contraindicated as the principal means of guidance during invasive procedures when realtime imaging is needed (e.g., CT Fluoroscopy procedures). In addition, the physician must verify navigation accuracy using an adequate verification method when used with Navigation Systems during surgical procedures.

### 6. Comparison of Technological Characteristics with the Predicate Device:

As detailed in Section 12 of this 510(k) Premarket Notification, the modified Airo CT System, for its intended use, is of comparable type in design, material, functionality, technology and is considered substantially equivalent to its baseline device Airo CT System (K131431, cleared on September 26, 2013) based on the following comparison.

Most importantly, the differences noted below and/or in the comparison table raise no new issues of safety or effectiveness based on all testing performed and presented in this 510(k) submission:

- Sequential Axial Scanning Mode
- Tube Current Modulation Feature (Helical only)
- . Metal Artifact Reduction Algorithm
