Intended Use

The NAOMI-DPX D100 is indicated for use in acquiring Panoramic radiographic images at the dento-maxillofacial region. The image generated is displayed on a computer monitor. It is intended to replace radiographic film/screen system in dental diagnostic procedures

Device Story

Digital X-ray imaging system designed to replace conventional film/screen systems in dental clinics. Device captures X-ray photons incident on a scintillator, converting them to light photons, which are then converted to electrical signals via a CCD sensor. NAOMI-DPX software processes these signals to capture and display panoramic radiographic images on a computer monitor. Used by dental professionals to assist in diagnostic procedures. Output allows clinicians to view dento-maxillofacial anatomy digitally, facilitating diagnosis and treatment planning.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

Solid-state X-ray imager; scintillator-based photon conversion; CCD sensor for electrical signal conversion; digital image capture; software-based display. No specific material standards or connectivity protocols detailed.

Indications for Use

Indicated for patients requiring panoramic radiographic imaging of the dento-maxillofacial region for dental diagnostic procedures.

Regulatory Classification

Identification

An extraoral source x-ray system is an AC-powered device that produces x-rays and is intended for dental radiographic examination and diagnosis of diseases of the teeth, jaw, and oral structures. The x-ray source (a tube) is located outside the mouth. This generic type of device may include patient and equipment supports and component parts.

#### · Device Description:

The NAOMI-DPX-D100 provided digital image capture for conventional film/screen systems. It is intended to replace the radiographic film/screen systems.

The x-ray photons incident to the NAOMI-DPX-D100 are detected and converted into the light photons at the scintillator. The light photons are detected and converted into the electrical signal at the CCD. NAOMI-DPX software captures and displays the image.

### Indications for Use:

The NAOMI-DPX-D100 provides digital image capture for conventional film/screen radiographic examinations. The device is intended to replace the radiographic film/screen systems in panoramic dental diagnostic procedures.

Section 5: 510(k) Summary

## Comparison to predicate:

The use of the NAOMI-DPX-D100 is the same as predicate devices. The value that evaluate image quality is different from NAOMI, however, most of the specifications are the same or better than NAOMI.

#### Conclusion:

l

The performance data demonstrate that NAOMI-DPX-D100 is as safe and effective as the predicate devices (CDR-PAN MODEL4700, Signet DXIS and DIGIPAN DPI). It is opinion of RF Co.,Ltd. strongly believe that the NAOMI-DPX-D100 described in this submission is substantially equivalence to predicate device (NAOMI).

Trade/Device Name: Digital X-Ray Imaging System. NAOMI-DPX-D100 Regulation Number: 21 CFR 872.1800 Regulation Name: Extraoral source x-ray system Regulatory Class: II Product Code: MUH, EHD, and MQB Dated: December 7. 2011 Received: December 8, 2011

Dear Mr. Kubo:

This letter corrects our substantially equivalent letter of January 5, 2012.

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration. Iisting of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into class II (Special Controls), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.

You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807): labeling (21 CFR Parts 801 and 809): medical device reporting (reporting of

{3}------------------------------------------------

medical device-related adverse events) (21 CFR 803); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
