| Device Description Summary | | 21 CFR 807.92(a)(4) |
| NOMAD Pro 3 Handheld X-ray System is a battery-operated, portable dental X-ray source designed for handheld operation. It is designed to produce diagnostic quality X-rays images utilizing either film or digital imaging techniques. The NOMAD Pro 3 Handheld X-ray System is designed for use in a dental office. It can also be used in other similar environments (orthodontic office, general practitioner's office, hospital ward, etc.) where appropriate safeguards are implemented. The device uses a rechargeable battery to allow for the use of the NOMAD Pro 3 Handheld X-ray System where transportation or use of other x-ray devices might be prohibitive due to the other device's size and/or lack of mobility. System Description and Overview: The NOMAD Pro 3 Handheld X-ray System is an X-ray device with a DC generator. The handheld device features a main unit (tube head), rechargeable battery (handset), charger, and charger AC/DC power supply. The power is supplied by a rechargeable Lithium-ion battery core pack built into a handset. This facilitates portability of the device. A beam-limiting cone is incorporated within the device. Internal and external shielding provide sufficient radiation protection to allow the clinician to remain in the operatory with the patient. To make the system as simple as possible for the operator, NOMAD Pro 3 Handheld X-ray System uses a fixed tube voltage of 65kV and a fixed tube current of 2.5mA. The only operator-adjustable parameter is the exposure time. This adjustment can be quickly accomplished through the user-friendly control panel. The battery core pack consists of standard production, high discharge, cylindrical, Lithium-ion cells. The vendor builds the cells into custom, potted enclosure which also contains control and safety circuitry in the form of a semi-custom Battery Management Unit (BMU). The internal potting provides protection against liquid ingress and further inhibits flame propagation in the event of a single cell failure. The BMU provides charge control, discharge control, battery capacity management, safety control and communication. The electrical interface includes a two-wire serial interface which may be used to obtain status of the battery core pack. | | |

Control buttons, display, and a trigger provide the primary operator interface. Exposure settings can be selected and displayed. Voltage (65 kV) and current (2.5 mA) are fixed with the exposure time varying based on patient type, detector type, and anatomical feature. Exposures can be completed using the trigger. The device can be used with three detector types: film, digital imaging intraoral sensors, and phosphor plates.
User warnings and markings will be on the upper portion of the device near the user interface. Technical and regulatory markings will be on the underside of the device, top of the handset (not visible when attached to device), and bottom of charging cradle.
Principles of Operation: The NOMAD Pro 3 Handheld X-ray System is used like any other extraoral dental X-ray source for intraoral application. An image receptor, such as film, is placed in the patient's oral cavity behind the teeth. The device is powered on, and the appropriate exposure time is set by the operator. The operator should follow appropriate instructions to ensure proper alignment of the X-ray beam to the receptor, and proper positioning of the receptor in the patient's mouth. To prevent inadvertent exposure to X-rays, the operator must first press and release the trigger to enable and then ready the device. A flashing green ENABLED indicator light and an audible signal confirm that the NOMAD Pro 3 Handheld X-ray System is enabled. X-rays are initiated by pulling and holding the trigger on the handle for the duration of the exposure. The system has numerous alarms and alerts to communicate with the operator.

| **Indications for Use Comparison** | **21 CFR 807.92(a)(5)** |
| The Indications for Use is identical to the Indications for Use of the predicate device. | |
| **Technological Comparison** | **21 CFR 807.92(a)(6)** |
Details of the similarities between subject and predicate devices:
The similarities between Subject Device and the Predicate Device are the Indications for Use as well as the Subject's Device most of the technological characteristics, such as: the energy source which is provided by the same Rechargeable 21.6 C DC Li-Ion battery core pack, or the user interface which allows the selection of several user-selectable preset time, the same as the predicate's device. The hard-shell case and the exposure switch, which has the trigger located on the handset, are as well the same as the predicate. The Battery specifications, starting with the capacity of 1.7 A-Hr. Enabling a recharge capability of 70% remaining capacity after 300 cycles to the duty cycle of 1:60 to the waveform which is constant potential (DC) and the device mA of 2.5 fixed are exactly the same as the predicate device.
Details of the differences between subject and predicate devices:
There are no major differences, however, there are some minor differences between Subject Device and Predicate Device. The differences originate from the device weight and dimensions which are adapted to 6.4 lbs. a very light increase of 0.4 lbs. from the 6.0 lbs. of the predicate device for the weight and as well the device dimensions which are being adjusted to 10.7"L x 11.6"H x 6.25"W from the predicate's device 11"L x 10.5"H x 5.5"W. The Backscatter radiation protection of 6.25" remains the same for the subject device as well as the source to skin distance, remaining at 21cm. The backscatter shield will be comprised of either bismuth-acrylic or lead-acrylic; the predicate device used only lead-acrylic. The exposure time adjusts to 0.04 – 1.0 seconds in 0.01 increments from the predicate's 0.02 – 1.0 seconds in 0.01 increments due to the removal of the timer settings of 0.02 and 0.03, and the subject device kVp value passing as well to 65kVp from the predicate's 60kVp. As a final adjustment for the subject device, the control mechanism tube lists as an Analog control system for the kV & mA values which is a rephrasing from the predicate's programmable logic device for the same values.

Bench comparison testing demonstrated that NOMAD Pro 3 produced diagnostic-quality intraoral images on both adult and pediatric phantoms equivalent to or better than the predicate device at matched exposures, and all evaluation cases passed. Compliance testing verified the NOMAD Pro 3 met all applicable essential performance and safety requirements, with all standards clauses evaluated passing. Compliance testing confirmed that NOMAD Pro 3 satisfied radiation protection, filtration, leakage radiation, HVL, and beam limitation requirements, with all measured conditions meeting acceptance criteria.
Filtration, kV, and preset characterization testing demonstrated that increased filtration and 65 kV operation maintained or improved image quality without adverse effects, and no test elements failed. Scatter radiation characterization at 65 kV with lead and bismuth shields showed that operator exposure remained below regulatory dose thresholds under worst case conditions, and no measurements exceeded applicable limits. Design verification testing of the backscatter shield confirmed that drop performance, dimensional inspection met acceptance criteria, and backscatter radiation measurements met all established criteria as below dose limits.
Testing of the high voltage power supply confirmed acceptable electrical performance before and after mechanical shock events, and all required output stability evaluations passed. Environmental, mechanical, ingress protection, lifetime cycling, and attachment strength evaluations of the new housing design all passed, confirming suitability of the updated housing. Impedance testing of the new housings demonstrated uniformly low impedance values supporting improved electromagnetic interference mitigation, with all readings within acceptable ranges. Evaluation confirmed correct short shot event detection, linearity of X ray output, and proper operation of new keypad/trigger hold diagnostic indicators, with all functional checks passing.
Clinical data is not needed to characterize performance and establish substantial equivalence. The non-clinical test data characterize all performance aspects of the device based on well-established scientific and engineering principles. Clinical testing has not been conducted on this product. In lieu of clinical studies, the device was evaluated using adult and pediatric phantoms incorporating real teeth and bone to simulate clinically relevant anatomical conditions. In addition, step wedge testing was performed to further characterize device performance across a range of tissue equivalent densities. The step wedges represent varying anatomical features, from thin soft tissue equivalent sections through the thickest steps corresponding to teeth and bone. These evaluations collectively provide a robust assessment of the device's performance under expected conditions of use.
As a result of the non-clinical tests performed in the summary above, all acceptance criteria are fulfilled and tests passed in accordance with product's functional requirement specifications and applicable standards. The verification and validation testing performed was considered adequate in supporting a substantial equivalence determination. Based on the tests performed, it can be determined that the proposed device is substantially equivalent in performance aspects to the predicate device.
Conclusion:
Based on a comparison of intended use, indications for use, technological characteristics, principle of operation, features, and
{7}
performance data, the device NOMAD Pro 3 is deemed to be substantially equivalent to the predicate device KaVo NOMAD Pro 2 as it satisfies all criteria of substantial equivalence and does not raise new concerns regarding substantial equivalence: (1) Indications for Use, (2) Technological Characteristics, and (3) Performance Data. NOMAD Pro 3 does not introduce fundamentally new scientific technology, and the nonclinical tests demonstrate that the device is substantially equivalent.
