The gantry has omni-directional 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.
Indications for Use:
The NL5000 [OmniTom] system is intended to be used for x-ray computed tomography applications for anatomy that can be imaged in the 40 cm aperture, 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:
NeuroLogica Corporation believes that the OmniTom system, for its intended use, is of comparable type in design, material, functionality, technology and is substantially equivalent to the cleared predicate device - CereTom (K051765).
Similarities
- Material: The OmniTom uses similar material to CereTom (K051765) such as, x-■ ray generator, slip ring, rotational bearing, and motion control systems.
- . Design: The OmniTom is similar in general design principle to CereTom (K051765). Specifically, it shares most of the control system designs and features of the CereTom.
Differences
- I Detector Material: The scintillation properties of the detector material Gadolinium Oxysulfide used in OmniTom CT system are more promising than the detector material Solid State CdWo4 used in the CereTom system (predicate device
5
K051765). This material has already been cleared for use in the reference device GR40CW Retrofit Kit (K153401 cleared 12/21/2015) which is a Solid State X-ray Imager manufactured by Samsung Electronics Co., Ltd.
- Tablet: OmniTom uses a tablet for running CT application software instead of a PC laptop used with CereTom. A tablet is an accompanying part of each OmniTom scanner and is designed to be used as the control unit to operate all respective functions of the system.
- . Internal Drive System: CereTom had an accessory drive system which when connected with the scanner allowed mobility while OmniTom has an internal drive system providing easy movement of the scanner.
- Battery: Lithium batteries are used in OmniTom instead of the lead acid batteries in CereTom are designed and tested to IEC 62133 and UN/DOT 38.3 for safety and transportation.
- Automatic Exposure Control: AEC was not offered on the CereTom system at the 트 time of 510(k) clearance (K051765) but introduced as a device modification through a software/firmware upgrade. OmniTom is XR-29 compliant and as such includes four key features of CT equipment that enable optimization or management of radiation dose delivery - dose structured reporting, CT dose check, AEC and pediatric and adult reference protocols. AEC feature has been verified as part of IEC 60601-2-44, clause 203.102.
- Contrast and Bolus Tracking: OmniTom does not control the contrast injection or the delivery of the contrast volume however has the ability for helical and dynamic scanning. For example, bolus tracking is used for CT Angiography applications.
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.

- ISO 14971 Medical devices Application of risk management to medical devices 트
In addition to conformance to the above harmonized standards, OmniTom quality assurance activities include the following:
- . Risk analysis and mitigation
- I Software verification and validation testing
- System verification and validation testing l
- I Image quality tests
- 트 Testing at unit level
Guidance documents specifically related to premarket submissions like FDA management of cybersecurity in medical devices, software contained in medical devices, pediatric medical devices and conformance with IEC standards were utilized during the development of OmniTom device.
Software is critical to the operation of the OmniTom CT scanner and a malfunction or design flaw in the software could result in delivery of appropriate medical care. As such, the risk management analysis identified potential hazards which were controlled
11
and mitigated during development of OmniTom. The verification/validation testing ensured the safety and effectiveness of OmniTom.
Image quality metrics such as noise, slice thickness, low and high contrast resolution, radiation metrics, and modulation transfer function were measured utilizing phantom image quality tests in accordance with the equipment performance standards for diagnostic x-ray systems administered by the FDA. Subsequent testing for artifact analyses associated with typical clinical techniques demonstrated the performance of the CT system in the presence of implants.
Phantom image evaluations were performed for pediatric scans along with clinical images for adult brain exams. The data provided clinical demonstration of the operation of the device and the images reviewed by a board-certified radiologist were of diagnostic quality.
The OmniTom scanner successfully demonstrated that it has comparable image quality as the predicate device CereTom (K051765) and meets all the image quality criteria that are used for testing the CereTom.
Conclusion
Based upon the above considerations, NeuroLogica Corporation, subsidiary of Samsung Electronics, believes that the OmniTom CT system is of comparable type in design, functionality, and technology and is, for its intended use, substantially equivalent to the predicate device CereTom (K051765).
The proposed modifications do not result in any new safety or effectiveness concerns. The OmniTom CT system performs as well in its intended use as similar devices currently on the market.
