• Submission Type: Special
• Regulation: 21 CFR 892.1680
• Device Class: Class 2

Intended Use

The BSD3543(BT-DA22-IA) detector is indicated for digital imaging solution designed for general radiographic system for human anatomy. It is intended to replace film or screen based radiographic system in all general-purpose diagnostic procedures. It is not to be used for mammography.

Device Story

The BSD3543 is a digital X-ray flat panel detector that intercepts X-ray photons; a scintillator (Gadolinium Oxysulfide or Cesium Iodide) converts these into visible light, which is then captured by an amorphous silicon (a-Si) TFT array to generate electrical signals. These signals are converted to digital values and transmitted to an integrated PC and X-ray generator system. The device is used in clinical settings by healthcare professionals to digitize X-ray images for diagnostic review, information management, and network sharing. By replacing traditional film/screen systems, it enables efficient digital radiography, potentially improving diagnostic workflows and image management. The system produces raw image data, which is processed by viewing software for clinical interpretation.

Clinical Evidence

No clinical data. Substantial equivalence was established through bench testing, including electrical safety (IEC 60601-1), electromagnetic compatibility (IEC 60601-1-2), and performance metrics (MTF and DQE) comparing the subject device to the predicate.

#### IV. DEVICE DESCRIPTION

BSD3543(BT-DA22-IA/BT-DB22-IA) is a digital X-ray flat panel detector which intercepts x-ray photons and the scintillator (BT-DB22-IA(Gdos) / BT-DA22-IA(CsI)) emits visible spectrum photons that illuminate an array of photo (a-SI)-detector that creates electrical signals. After the electrical signals are generated, it is converted to digital values, and the images will be displayed on the monitor. This device should be integrated with an operating PC and an X-Ray generator. It can digitalize x-ray images and transfer them for radiography diagnostics. Advanced digital image processing allows considerably efficient diagnosis, all kinds of information management, and sharing of image information on network.

When compared to the predicate device (K160204), the BSD3543(BT-DA22-IA/BT-DB22-IA) presented in this submission has the same characteristics in the following:

- Intended Use
- Pixel pitch
- · Resolution
- · Operating principle
- · Basic design
- · Viewing software

The imaging area and pixel matrix of BSD3543(BT-DA22-IA/BT-DB22-IA) and the predicate device are different but they would not adversely affect the use of the product. Both devices are substantially equivalent in basic design, function, operational principles and intended use.

#### SUMMARY OF NON-CLINICAL TESTS VII.

The bench testing performed to compare the subject devices to the predicate followed FDA's guidance document: "Guidance for the Submission of 510(k)s for Solid State Xray Imaging Devices."

To minimize electrical and mechanical hazards, BONTECH adheres to recognized and established industry practice, and all equipment complies with the relevant FDA and international standards. For example, electrical, mechanical, environmental safety and

{7}------------------------------------------------

performance testing according to standard EN60601-1:2006+A1:2013 or IEC60601-1:2005 3.0 was performed and EMC testing was conducted in accordance with standard IEC 60601-1-2: 2007, EN 60601-1-2:2007

Through verification and validation activities, engineering testing and standards compliance testing were successfully conducted and did not raise any new safety questions or concerns or identify new risks.

The instructions for use are included within the device labeling, and the information provided will enable the user to operate the device in a safe and effective manner :

Electrical Safety:

Testing was conducted in accordance with AAMI ANSI ES60601-1:2005/(R)2012 and A1:2012. Medical electrical equipment - Part 1: General requirements for basic safety and essential performance (IEC 60601-1:2005, MOD)

## Electromagnetic Compatibility:

Testing was conducted in accordance with IEC 60601-1-2:2007 Medical Electrical Equipment - Part 1-2: General Requirements For Basic Safety And Essential Performance - Collateral Standard: Electromagnetic Compatibility - Requirements And Tests

## Software:

The viewing software for the subject device is identical to the predicate device. Software verification and validation testing as recommended in FDA's Guidance Document "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." (May 11, 2005)

Performance testing was conducted to show that the subject device performs as intended and equally or better than the performance of the predicate device.

The non-clinical performance testing constrains that the main physical values for comparison of X-ray devices like DQE and MTF are basically equivalent to the predicate device BSD4343 (K160204). The results show that BSD3543(BT-DA22-IA/BT-DB22-IA) offer similar or better resolution performance than BSD4343 at 0 ~ 3.5lp/mm spatial frequencies. Moreover, the ability of BSD3543(BT-DA22-IA/BT-DB22-IA) to utilize the input image signal are more efficient than BSD4343 at same patient exposure as shown in the detective quantum efficiency graph.

These tests were conducted under conditions of single and double pumping mode and for the varying power sources (e.g., AC/DC power vs. battery power).

The Detector is tested for the integration to a generator and viewing software as below. -Generator:

- > kV Range: 40~125kV, 1kV step (Optional 40~150kV)
- > mA Range: 10 to 500mA
- > Timer Range: 0.001 to 10 sec, 38 steps
