# IV. DEVICE DESCRIPTION

The REMEX Xcam6 is a handheld and portable general-purpose X-ray system intended for use by qualified and trained clinicians to obtain diagnostic radiographic images of patient's extremities.

The REMEX Xcam6 serves as an X-ray source and is designed to be used in conjunction with a Flat Panel Detector (FPD), which is not included as part of the system. The FPD is connected to a computer equipped with imaging software that enables image acquisition, display, manipulation, storage, and transmission.

The X-ray source is securely enclosed within the housing of the handheld unit, and the device does not come into direct contact with the patient during use.

During imaging procedures, the patient is positioned appropriately—either sitting or lying down—and the X-ray receptor is aligned accordingly. The patient is instructed to remain still while the operator sets the exposure parameters and initiates the radiographic exposure.

The operator has control over the following exposure parameters:

1. Tube Voltage (kVp): Adjustable from 40 to 90 kVp, in 1 kV increments.
2. Tube Current (mA): Adjustable from 2 to 6 mA, in 1 mA increments.
3. Exposure Time: Adjustable from 0.06 to 2.00 seconds, in 0.01-second increments.

# V. INDICATIONS FOR USE

Portable X-ray Equipment REMEX Xcam6 is intended to be used in a hospital or clinic setting under the supervision of a qualified and trained clinician. This product is used as an x-ray source to produce diagnostic x-ray images of patient's extremities using an X-ray detector. It may be used in handheld or stand-mounted configurations for acquiring diagnostic radiographic images of extremities.

The device is not intended for mammography.

The REMEX Xcam6 is not intended to replace a stationary radiographic system, which may be required for full optimization of image quality and radiation exposure for different exam types.

The predicate device, TR90BH, is intended for acquiring X-ray images of the patient's head, abdomen, chest, and extremities, whereas the REMEX Xcam6 is intended for diagnostic imaging of body extremities only. This difference does not materially alter the primary intended use, which is the acquisition of diagnostic X-ray images of extremities.

The REMEX Xcam6 differs from the predicate device in certain design aspects, including physical dimensions, weight, power source, and X-ray tube configuration. These differences reflect design optimizations to enhance portability and do not introduce new questions of safety or effectiveness. Although there are differences in tube current range and exposure time between the two devices, these parameters have been fully validated through bench testing and clinical image evaluations. The REMEX Xcam6 has also undergone testing and verification for electrical safety, electromagnetic compatibility (EMC), and software performance in accordance with applicable standards.

The results of these evaluations demonstrate that the REMEX Xcam6 is as safe and effective as the predicate device and support a determination of substantial equivalence.

The results confirm that the image quality and radiation dose characteristics of the subject device are substantially equivalent to those of the predicate device.

- Software Verification and Validation Testing

Software verification and validation were performed in accordance with IEC 62304:2006/A1:2015, Medical device software – Software life cycle processes. The REMEX Xcam6 software is classified as Class B under IEC 62304, indicating that a software failure or latent defect could pose a low level of risk, potentially resulting in non-serious injury to the patient, operator, or others. Cybersecurity was addressed per FDA guidance, “Cybersecurity in Medical Devices: Quality System Considerations and Content of Premarket Submissions”.

- Clinical Performance Testing

A limited clinical test was conducted to confirm the device’s capability to produce diagnostic images of body extremities. The acquired images were reviewed and assessed by a board-certified radiologist, who verified that the device performed successfully and that the image quality was suitable for diagnostic interpretation.

VIII. CONCLUSIONS

A comparison of the intended use and technological characteristics demonstrates that the REMEX Xcam6 is at least as safe and effective as the predicate device. The analysis supports a determination of substantial equivalence between the subject device and the predicate. Performance data, including bench testing and clinical image evaluations, further support the safety and effectiveness of the REMEX Xcam6. These results confirm that the device performs as intended under the specified use conditions.

Accordingly, the REMEX Xcam6 is considered substantially equivalent to the predicate device, in accordance with the criteria outlined in 21 CFR § 807.92.
