Intended Use

The SKR 3000 is indicated for use in generating radiographic images of human anatomy. It is intended to a replace radiographic film/screen system in general-purpose diagnostic procedures. This device is not indicated for use in mammography, fluoroscopy, and angiography applications.

Device Story

SKR 3000 is a stationary digital X-ray system using flat-panel detectors (FPDs) to capture radiographic images. Input: X-ray radiation attenuated by human anatomy. Transformation: FPD converts X-rays to digital signals; Console CS-7 software performs image processing (gradation, frequency, dynamic range compression, smoothing, rotation, grid removal/scatter correction). Output: Diagnostic image data transmitted to filing systems, printers, or displays. Used in clinical settings by healthcare professionals. Benefits: Replaces film/screen systems with digital workflow; provides rapid image acquisition and processing. New P-82/P-85 detectors feature silver-ion infused antibacterial surfaces and varying Li-ion capacitor configurations.

Clinical Evidence

No clinical data. Substantial equivalence demonstrated through bench testing, including performance verification per FDA guidance for solid-state X-ray imaging devices, risk management, and compliance with AAMI/ANSI ES 60601-1, IEC 60601-1-2, and ISO 10993-1 standards.

Technological Characteristics

Indirect conversion FPD (CsI scintillator); film-based TFT substrate; 16-bit A/D conversion; 100/200 μm pixel size. Connectivity: Wired Ethernet/Wireless LAN (IEEE802.11a/n, WPA2-PSK/AES). Power: Li-ion capacitors. Surface: Silver-ion infused antibacterial. IP56 rating. Software: CS-7 console for image processing.

Indications for Use

Indicated for generating radiographic images of human anatomy in general-purpose diagnostic procedures; includes pediatric patients. Not for mammography, fluoroscopy, or angiography.

Regulatory Classification

#### Dear Jan Maniscalco:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

# Device Description

The digital radiography SKR 3000 performs X-ray imaging of the human body using an Xray planar detector that outputs a digital signal, which is then input into an image processing device, and the acquired image is then transmitted to a filing system, printer, and image display device as diagnostic image data.

- This device is not intended for use in mammography
- This device is also used for carrying out exposures on children.

Image /page/4/Picture/0 description: The image shows the Konica Minolta logo. The logo consists of a blue circle at the top with several white horizontal lines running across it. Below the circle is the text "KONICA MINOLTA" in a bold, sans-serif font.

The Console CS-7, which controls the receiving, processing, and output of image data, is required for operation. CS-7 implements the following image processing; gradation processing, frequency processing, dynamic range compression, smoothing, rotation, reversing, zooming, and grid removal process/scattered radiation - correction (Intelligent-Grid). The Intelligent-Grid is cleared in K151465.

This submission is to add new flat-panel x-ray detectors (FPDs), P-82 and P-85, into the SKR 3000. The P-82 and P-85 employ the same surface material infused with Silver ions (antibacterial properties) as the predicate device. The only difference between the P-82 and P-85 is the number of Li-ion capacitors. The P-85 has two Li-ion capacitors and the P-82 has one. These new P-82 and P-85 are not applicable to the serial radiography which acquires multiple frames of radiography image serially.

The FPDs used in SKR 3000 can communicate with the image processing device through the wired Ethernet and/or the Wireless LAN (IEEE802.11a/n and FCC compliant). The WPA2-PSK (AES) encryption is adopted for a security of wireless connection.

The SKR 3000 is distributed under a commercial name AeroDR 3.

## Indications for Use

This device is indicated for use in generating radiographic images of human anatomy. It is intended to a replace radiographic film/screen system in general-purpose diagnostic procedures.

This device is not indicated for use in mammography, fluoroscopy, and angiography applications.

#### Performance Data

The SKR 3000 is designed to comply with the following standard; AAMI/ANSI ES 60601-1 (Ed.3.1), IEC 60601-1-2 (Ed.4.0), and ISO 10993-1 (2018). The performance tests according to the "Guidance for the Submission of 510(k)s for Solid State X-ray Imaging Devices" and the other verification and validation including the items required by the risk analysis for the SKR 3000 were performed and the results demonstrated that the predetermined acceptance criteria were met. The results of risk management did not require clinical studies to demonstrate the substantial equivalency of the proposed device.

## Conclusion

The SKR 3000 has the same intended use and indications for use, technological characteristics, and principal operations. The technological differences raised no new issues of safety or effectiveness as compared to its predicate device (K210619). Performance tests demonstrate that the SKR 3000 performs according to specifications and functions as intended. All the information to demonstrate assurance of our evaluation is attached to relevant sections of this submission.

Therefore, as for our conclusion, the SKR 3000 is substantially equivalent to the predicate devices and presents no new questions of safety or effectiveness.
