10. Operating principle
The purpose of this unit is diagnose clinical structures of a tooth and head areas mainly by using the characteristics of permeability from X-ray. The principle of functioning are as following. The machine is made of X-ray generator and arms in which transfers X-ray signals to a sensor in 2D. Also, an object that has a magnification is required in a distance. Moreover, the unit has to be adjustable depending on height of a patient and PC system to reconstruct an image.
The arm parts are controlled for rotating and linear moving to synchronize between the sensor and X-Ray Co.,Ltd Page 2

ray generator to get the image of interests. The purpose of this mechanism is to provide the images in 2D or/and 3D as preferred to diagnose in a monitor. CBCT provides in 3D images as reconstructed and Panorama is to diagnose the structures in a panoramic view. Cephalometric allows for orthodontic treatment. These 3 functions could be in 1 system, Panorama with Cephalometric, or Panorama only system depending on the needs. To provide the features as mentioned above, digital transferring from permeated X-ray to absorbing to the sensor is essential and all the process are proceed in Detector. Detector transfers X-ray to light depending on the structure materials. Detector is separated into indirect method that the light is changed to digital signals on photodiode and direct method in which the light is directly transferred to digital signal. This unit is using both direct method depending on the interior structure materials.

11. Comparison with predicate device
The product is principally just the same as in the previous 510(k) #K160525.
The indications for use are expanded to include the model scan. But, the operating principle of the model scan is thought to be similar to previous 510(k) #K170066.
The expanded intended use of the RCT800 and the predicate device #K160525 and #K170066 is identical.
The compared technical features for imaging parameters, resolution, and other basic characteristics are matching very closely, and the differences are so small that they do not have any effect on performance in practice. Both devices conformance standards.

12. Safety and Effectiveness Information
RCT800 system described in this 510(k) is similar to the predicate device in terms of indications for use, materials, safety characteristics, and X-ray source.
The following information further substantial equivalence between the subject device and predicate device.
The fundamental technological characteristics of the subject and predicate device are similar.
The imaging modes are similar; PANO, CEPH (Optional), CBCT, Model Scan All viewing software programs have been cleared with previous 510k submissions; RAYSCAN(K160525).
The sponsor tested the subject device in a laboratory and provided a non-clinical performance report. The same test protocol was used to test the performance of the subject and the predicate device for comparison. The sponsor certifies that adequate design and development controls (according to 21 CFR 820.30) were in place for manufacturing the subject device.
The differences are as follows.
- The subject device is equipped with new detectors, FXDD-0606CA, 1717SCC. And new High Voltage Generator, X-ray Tube for Model Scan.
Electrical, mechanical and environmental safety testing according to standard of IEC 60601-1: 2005/AMD1:2012(3.1 Edition), IEC 60601-1-3: 2008/AMD1:2013(Second Edition), IEC 60601-1-6:2010(Third Edition) and IEC 60601-2-63: 2012(first Edition) were performed. EMC testing was conducted in accordance with the standard IEC 60601-1-2: 2014(Edition 4.0).
The software of RCT800 saves the patient and image data and offers an inquiry function, in addition, supports the image generate function intended to obtain images using the RCT800 equipment and various sensors for diagnosis. And that has been validated according to FDA "Guidance for the Content d Premarket Submissions for Software Contained in Medical Devices" and "Content of Premarket Submissions for Management of Cybersecurity in Medical Devices" to assure substantial equivalence. The software for this device was considered as a "moderate" level of concern, since a failure or latent flaw in the software would not directly result in serious injury or death to the patient or operator. As a result, we identified the level of concern associated with new device and provided documentation consistent with that level. Based on our risk analysis of software, the difference does not affect its safety and effectiveness.
Bench testing was conducted according to FDA Guidance "Format for Traditional and Abbreviated 510(k)s, section 18, Performance Testing - Bench"
Bench testing is used to assess whether or not the parameter measured required for describing functionalities related to imaging properties of the dental X-ray device and patient dosage satisfies the designated tolerance.
Performance (Imaging performance) testing was conducted according to standard of IEC 61223-3-4 and IEC 61223-3-5.
All test results were satisfactory.
Non-clinical considerations were conducted in accordance with FDA Guidance for the submissions of 510(k)'s for Solid State X-ray Imaging Devices".
RCT800 is equipped with FXDD-0606CA. FXDD-0606CA is a new SSXI detector, which is used to capture an image in panoramic, CBCT and Model Scan mode.
Based on Non-Clinical Test results of FXDD-0606CA for the subject device, is similar to that of the SiX 650HD-E for the Predicate device. And equipped with 1717SCC is a new SSXI detector, which is used to capture an image in Cephalometric. Based on Non-Clinical Test results of 1717SCC for the subject device, is similar to that of the PaxScan 4336X for the Predicate device.
All test results were satisfactory.

Clinical considerations were conducted according to FDA Guidance "Format for Traditional and Abbreviated 510(k)s, section 20".
Clinical images were provided these images were not necessary to establish substantial equivalence based on the modifications to the device but they provide further evidence in addition to the laboratory performance data to show that the complete system works as intended.
For clinical testing, two licensed practitioners/clinicians observed and verified that dental X ray system from RCT800.
The clinical imaging samples are collected from the new detector on propose device at the 2 offices where the predicate device is installed on clinical consideration report for the clinical test images. These images were gathered from the new detector installed with RCT800 on any protocols with random patient age, gender, and size. As licensed practitioners or clinician diagnoses of the images, it might be proved that the clinical diagnosis and structures are acceptable in the region of interests.
12. Conclusions
In accordance with the Federal Food, Drug and Cosmetic Act, 21 CFR Part 807 and based on the information provided in this premarket notification. RAY Co., Ltd. concludes that the newly RCT800 is safe and effective and substantially equivalent to predicate device as described herein.
