Device Description
RAYSCAN α-3D, SM3D, M3DS and M3DL are 3D computed tomography for scanning hard tissues like bone and teeth. By rotating the C-arm, which houses a high-voltage generator, a X-ray tube and a detector on each end, CBCT images of dental maxillofacial structures are obtained by recombining data scanned from the same level at different angles. Functionalities include panoramic image option and cephalometric option.
More Information

No
The summary describes a standard dental X-ray imaging system (Panoramic, Cephalometric, CBCT) and its technical specifications. There is no mention of AI, ML, deep learning, or any related concepts in the intended use, device description, performance studies, or other sections. The focus is on image acquisition and reconstruction using traditional methods.

No.
The device is an imaging system used for diagnosis, not for therapy.

Yes
The device is described as an "extra-oral source x-ray system, which is intended for dental radiographic examination of the teeth, jaw, and oral structures." It is used to generate 3D images and for various studies (panoramic, implantology, TMJ, cephalometry), all of which are diagnostic activities.

No

The device description explicitly states it is an "extra-oral source x-ray system" and describes hardware components like a "C-arm, which houses a high-voltage generator, a X-ray tube and a detector". This indicates it is a hardware device with integrated software, not a software-only medical device.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Definition of IVD: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. These tests are performed outside of the body (in vitro).
  • Device Function: The RAYSCAN a-Expert3D is an extra-oral source x-ray system. It uses X-rays to create images of the teeth, jaw, and oral structures within the patient's body. It does not analyze samples taken from the body.
  • Intended Use: The intended use clearly states it's for "dental radiographic examination" and generating "dentomaxillofacial 3D images." This is an imaging device, not a diagnostic test performed on a sample.

Therefore, based on the provided information, the RAYSCAN a-Expert3D is a medical imaging device, not an In Vitro Diagnostic.

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 RAYSCAN a-Expert3D 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 RAYSCAN a-Expert3D 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 for the Submissions of 510(k)'s for Solid State X-ray Imaging Devices". 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 standard 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 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". 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.

10. Safety and Effectiveness Information

RAYSCAN α-Expert3D 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, Scan All viewing software programs have been cleared with previous 510k submissions; RAYSCAN(K190812).

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 maximum X-ray voltage of the tube has been changed from 90kV to 100kV
  • The minimum x-ray current of the tube has been changed from 4mA to 1mA
  • The Ceph(Scan) scan time has been changed from 20sec to 19.8sec
  • Detector (using One-shot).

However, X-ray voltage, X-ray current, one-shot ceph detector was identified in #K230753

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/AMD1:2017(first Edition) were performed. EMC testing was conducted in accordance with the standard IEC 60601-1-2: 2014(Edition 4.0).

The software of RAYSCAN α-Expert3D saves patient and image data and offers an inquiry function. In addition, it supports the image generate function intended to obtain images using the RAYSCAN a-Expert3D 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 for the Submissions of 510(k)'s for Solid State X-ray Imaging Devices". 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 standard 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 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". 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.

Pediatric information related to the use of this device is provided to users in compliance with FDA guidance "Pediatric Information for X-ray Imaging Device Premarket Notifications".

The features of RAYSCAN a-Expert3D 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 RAYSCAN a-Expert3D 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 RAYSCAN a-Expert3D is safe, effective and substantially equivalent to the predicate device as described herein.
