More Information

No
The summary describes a standard CBCT and panoramic x-ray system with cephalometric and model scan options. There is no mention of AI, ML, or any related technologies in the intended use, device description, performance studies, or key metrics sections. The focus is on image acquisition and quality, not automated analysis or interpretation using AI/ML.

No.

The device is an imaging system intended for diagnostic support, not for providing therapy or treatment.

Yes

The "Intended Use / Indications for Use" section explicitly states that the device is "intended to radiographic examination of the dento-maxillofacial, sinus, TMJ, Airway for diagnostic support".

No

The device description clearly states it is a "3D computed tomography scanner" and describes physical components like a "c-arm," "x-ray tube," and "detector," indicating it is a hardware device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are tests performed on samples such as blood, urine, or tissue that have been taken from the human body to detect diseases, conditions, or infections.
  • Device Function: The RCT800 is an imaging system that uses X-rays (CBCT, panoramic, cephalometric) to create images of anatomical structures within the body (dento-maxillofacial, sinus, TMJ, Airway, wrist). It does not analyze samples taken from the body.
  • Intended Use: The intended use is for radiographic examination and diagnostic support based on these images, not on the analysis of biological samples.

Therefore, the RCT800 falls under the category of a medical imaging device, not an In Vitro Diagnostic device.

Description of the test set, sample size, data source, and annotation protocol

Clinical images were provided, and while these images were not necessary to establish substantial equivalence based on the modifications to the device, they provide further evidence, in addition to the laboratory performance data, to show that the complete system works as intended.

The features of RCT800 were clinically tested and approved by two licensed practitioners/clinicians. Clinical imaging samples were collected from new detectors on the proposed device at the two offices where the predicate device was installed for the clinical test images. These images were gathered from all detectors installed with RCT800 using protocols with random patient age, gender, and size. A licensed practitioner reviewed the sample clinical images and deemed them to be of acceptable quality for the intended use.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Bench testing was conducted according to the FDA Guidance "Format for Traditional and Abbreviated 510(k)s," Section 18, "Performance Testing - Bench." Bench testing is used to assess whether the parameters required to describe functionalities related to imaging properties of the dental X-ray device and patient dosage satisfy the designated tolerance.

Performance (Imaging performance) testing was conducted according to the standards of IEC 61223-3-4 and IEC 61223-3-7. All test results were satisfactory.

Non-clinical considerations were conducted in accordance with the FDA Guidance "Guidance for the Submissions of 510(k)'s for Solid State X-ray Imaging Devices." Because the subject device uses the same detector as the predicate device, there are no significant differences between the two devices as a result of non-clinical testing.

Clinical considerations were conducted according to the FDA Guidance "Format for Traditional and Abbreviated 510(k)s," Section 20. Clinical images were provided, and while these images were not necessary to establish substantial equivalence based on the modifications to the device, they provide further evidence, in addition to the laboratory performance data, to show that the complete system works as intended.

The 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 substantiates the substantial equivalence between the subject device and predicate device. The fundamental technological characteristics of the subject and predicate devices are similar. The imaging modes are similar; PANO, CEPH (Optional), CBCT. All viewing software programs have been cleared with previous 510k submissions; RAYSCAN (K192737). 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 predicate devices 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 minimum X-ray current of the tube has been changed from 4mA to 1mA
  • The Magnification of Panorama has been changed from 1.3 to 1.31
  • Detector (using for CT, Pano and One-shot Ceph), Field of view.

However, X-ray current, magnification and one-shot ceph detector was identified in #K213226.

Electrical, mechanical and environmental safety testing according to the 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 patient and image data and offers an inquiry function. In addition, it supports the image generate function intended to obtain images using the RCT800 equipment and various sensors for diagnosis. That has been validated according to the FDA "Guidance for the Content of 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 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 a 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 the FDA Guidance "Format for Traditional and Abbreviated 510(k)s," Section 18, "Performance Testing - Bench." Bench testing is used to assess whether the parameters required to describe functionalities related to imaging properties of the dental X-ray device and patient dosage satisfy the designated tolerance.

Performance (Imaging performance) testing was conducted according to the standards of IEC 61223-3-4 and IEC 61223-3-7. All test results were satisfactory.

Non-clinical considerations were conducted in accordance with the FDA Guidance

"Guidance for the Submissions of 510(k)'s for Solid State X-ray Imaging Devices." Because the subject device uses the same detector as the predicate device, there are no significant differences between the two devices as a result of non-clinical testing.

Clinical considerations were conducted according to the FDA Guidance "Format for Traditional and Abbreviated 510(k)s," Section 20. Clinical images were provided, and while these images were not necessary to establish substantial equivalence based on the modifications to the device, they provide further evidence, in addition to the laboratory performance data, to show that the complete system works as intended.

The features of RCT800 were clinically tested and approved by two licensed practitioners/clinicians. Clinical imaging samples were collected from new detectors on the proposed device at the two offices where the predicate device was installed for the clinical test images. These images were gathered from all detectors installed with RCT800 using protocols with random patient age, gender, and size. A licensed practitioner reviewed the sample clinical images and deemed them to be of acceptable quality for the intended use.

11. 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, effective and substantially equivalent to the predicate device as described herein.
