No
The device is described as an x-ray computed tomography system primarily used for imaging. Its intended use is for diagnostic purposes (obtaining images for diagnosis), not for treating or preventing disease.
Yes
Explanation: The device is an x-ray computed tomography system intended for imaging anatomy to aid in diagnosis, as indicated by its "Intended Use" for "x-ray computed tomography applications" and the "Summary of Performance Studies" stating that images reviewed by a radiologist were of "diagnostic quality."
No
The device description clearly outlines numerous hardware components including an x-ray generator, detector array, gantry, power system, and drive systems, indicating it is a physical medical device, not software-only.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD devices are used to examine specimens (like blood, urine, or tissue) taken from the body. They are used to diagnose diseases or conditions based on the analysis of these samples.
- This device is an X-ray computed tomography (CT) system. It works by taking images of the inside of the body using X-rays. It does not involve the analysis of biological specimens.
The description clearly states its intended use is for "x-ray computed tomography applications for anatomy that can be imaged in the 40cm field of view, primarily head and neck." This is a form of medical imaging, not in vitro diagnostics.

The gantry has omnidirectional wheels that allow for robust diagonal, lateral, and rotational 360-degree movement and electrical drive system so the system can be moved easily to different locations.
Intended Use / Indications for Use
The OmniTom Elite CT system is intended to be used for x-ray computed tomography applications for anatomy that can be imaged in the 40cm field of view, primarily head and neck.
The CT system is intended to be used for both pediatric and adult imaging and as such has preset dose settings based upon weight and age. The CT images can be obtained either with or without contrast.
Comparison of Technological Characteristics with the Predicate Device
We modified the cleared OmniTom (K171183) within our design controls to include technology improvements, that include hardware features like movement controls, power system efficiency, ruggedized covers and bumpers, patient auto alignment and software features like metal artifact reduction. CT angiography (CTA), CT perfusion (CTP), bolus tracking, axial and helical AEC and other post reconstruction enhancements. Both the predicate device (K171183) and the subject device have the same intended use.
OmniTom Elite, for its intended use, is of comparable type in design, material, functionality, and technology and is substantially equivalent to the cleared predicate device – OmniTom (K171183).
Similarities
- . Design: The OmniTom Elite is similar in general design principle to OmniTom. and shares most of the control system designs and features of the OmniTom.
5
- . Components: The OmniTom Elite uses similar components as the predicate device (OmniTom) such as x-ray generator, Gd2O2S detector array, collimator, slip ring, and data acquisition system.
Differences
The following differences exist between the subject device (OmniTom Elite) and the previously cleared predicate device (OmniTom K171183).
- . Movement controls: The drive bar mechanism, system collision sensors, calibration were improved, in addition to audible and visual alerts for performance to avoid any possible unintentional or fast movement.
- . Power system efficiency: Improved distribution of power in the system and design of the lithium batteries, allowing maintenance and protection of downstream electrical components. The design changes mitigate any inadvertent system shutdowns while providing health status on the operational state of the CT system and design changes increased mean time between failures (MTBF) for these critical components.
- Ruggedized covers and bumpers: Design changes were made for improved durability of the CT system.
- Patient auto alignment: Camera allows for rapid positioning of the scanner at the head of the bed, eliminating the need to adjust the patient bed.
- . Metal artifact reduction (MAR): Streak artifacts are often seen around aneurysm clips, epilepsy probes or metal pins. The streaks can be reduced using MAR. Testing was carried out using an anatomical phantom and it was found that the MAR algorithm performs as indicated by successfully mitigating the streak artifacts that show up in the CT images without raising any new questions of safety or effectiveness of the device.
- CT angiography (CTA), CT perfusion (CTP), bolus tracking: OmniTom Elite has . the ability for helical and dynamic scanning and includes dedicated functionality for contrast scanning. Similar to the predicate, OmniTom Elite does not control the dose, rate or route of administration for the contrast agent.
- Automatic exposure control (AEC): Both axial and helical AEC are included in . OmniTom Elite for scanning with reduced radiation dose. AEC feature has been
6
verified as part of IEC 60601-2-44, clause 203.102 in OmniTom Elite similar to the predicate device.
- . Post reconstruction enhancements: Reconstruction algorithms were enhanced for better image quality with the addition of specific features to allow modified slice spacing and thickness, reduced field of view.
- . Mobile Stroke Unit: Rail and plate configuration is included in a kit for OmniTom Elite to be used in ambulance environment.
- . Accessories: OmniTom Elite has various adapters to allow scanning with all compatible beds, a pediatric platform that will allow scanning from head to torso of up to a typical 7-year-old and radiolucent skull clamp kits for use during imaging in neurosurgical environment.
- = Software: The software has undergone several updates since the OmniTom (K171183) was cleared. The updates were implemented to enhance the user experience and improve clinical workflow while using the CT system by adding features based on feedback from our current customers. The updated changes do not impact software. The OmniTom Elite software functions in a similar to manner to the predicate OmniTom (K171183) device.
The internal verification and validation activities and external testing of product safety and EMC / EMI was completed successfully. The differences noted above raise no new issues of safety or effectiveness based on all testing performed. Below a summary has been provided for the testing conducted.
