Intended Use

The BSD4343 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 Description

BSD4343 is a digital X-ray flat panel detector which intercepts x-ray photons and the scintillator (Gadox:Tb type) 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.

AI/ML Overview

The acceptance criteria and study proving the device meets them are described below for the BSD4343 Digital Flat Panel X-ray Detector.

1. Table of Acceptance Criteria and Reported Device Performance

The provided document does not explicitly state quantitative "acceptance criteria" for performance metrics in a pass/fail format. Instead, it demonstrates substantial equivalence to a predicate device (LLX240AB01) by showing similar or better performance in key imaging characteristics and adherence to safety standards. The "Reported Device Performance" below is derived from the comparison table and the "Non-clinical study" section, relative to the predicate.

2. Sample Size Used for the Test Set and Data Provenance

The document does not explicitly mention a "test set" in the context of a clinical study with patient data. The "non-clinical study" section refers to physical values for comparison (DQE, MTF, NPS) with the predicate device. These are typically measured on phantoms or test objects, not human subjects, and therefore do not involve patient-specific sample sizes or data provenance in the clinical sense.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications

Since no clinical "test set" with patient data requiring expert ground truth is described, this information is not applicable. The basis for comparison is the technical specifications and measured performance of the device against a predicate, typically using engineering metrics and standards.

4. Adjudication Method for the Test Set

Not applicable, as no clinical "test set" requiring adjudication or expert consensus for ground truth is described.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

No, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. The submission relies on non-clinical performance data and substantial equivalence to a predicate device.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

Yes, the performance testing described is standalone, focusing on the inherent technical capabilities of the device (such as DQE, MTF, NPS) and its compliance with safety and electrical standards. These are measures of the device's technical performance, independent of human interpretation in a clinical setting.

7. The Type of Ground Truth Used

For the non-clinical performance metrics (DQE, MTF, NPS), the "ground truth" would be established through highly controlled measurements using calibrated equipment and phantoms according to industry standards. These are objective physical measurements, not subject to expert consensus, pathology, or outcomes data in the traditional sense of medical image evaluation. For regulatory compliance, the "ground truth" is defined by the requirements of the standards (e.g., IEC 60601-1).

8. The Sample Size for the Training Set

This information is not applicable. This device is a digital X-ray detector, which is hardware, not an AI algorithm that requires a training set of data.

9. How the Ground Truth for the Training Set Was Established

This information is not applicable, as the device is not an AI algorithm and therefore does not have a "training set."

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

8. Description of non-clinical tests.

- Non-clinical study

The non-clinical performance testing constrains that the main physical values for comparison of X-rav devices like DQE. MTF NPS are basically equivalent to the predicate device LLX240AB01 (K102587). The results show that BSD4343 offer similar or better resolution performance than LLX240AB01 at 0 ~ 3.5lp/mm spatial frequencies. Moreover, the ability of BSD4343 to utilize the input image signal are more efficient than LLX240AB01 at same patient exposure as shown in the detective quantum efficiency graph.

-Electrical safety and EMC

BSD4343 has been tested for electrical safety standard IEC 60601-1: 2005 + CORR. 1 (2006) + CORR. 2 *2007) + AM1 (2012) and electromagnetic compatibility IEC 60601-1-2: 2007

The software validation and verification testing was also performed. The results of nonclinical testing indicate that the BSD4343 detector is as safe and effective as the predicate device.

Compliance evidences were submitted for the following standards:

  • IEC 60601-1: Test Report issued by 3rd party testing lab A
  • A IEC 60601-1-2: Test Report issued by 3rd party testing lab
  • A ISO 14971: Risk management file

9. Description of clinical tests.

Images reviewed were not necessary to establish substantial equivalence based on the modifications to the device as evidenced in the laboratory performance data to show that the subject device operates as the indicated.

10. Conclusion as to Substantial Equivalence

The BSD4343 detector is substantially equivalent to the predicate device LLX240AB01 (K102587). Both subject and predicate devices are same or very similar in the intended use, the design principle, the performance and the applicable standards. Some characteristics, for example, their appearance, pixel pitch and weight are different. However the compliance reports, performance demonstrations that these differences do not raise any new questions of safety and effectiveness. Therefore, BONTECH Inc. concludes the BSD4343 digital flat panel detector is substantially equivalent with the predicate device LLX240AB01 (K102587) of Samsung Mobile Display Co., Ltd.
