x-mind dc (and Owandy-RX DC under trademark Owandy Radiology) is an X-ray unit, in particular extraoral source of X-rays, intended for intra-oral radiographic exams for diagnostic purposes related to anatomy of teeth and adjacent oral structures both on adult and pediatric patients, using specific x-ray detectors (chemical films, phosphor plates or digital xray sensors) that are not part of the device.

The device is operated and used by dentists, radiologists and other legally qualified health care professionals.

Device Description

x-mind dc consists of the following parts:

1 X-ray control unit (timer)
2 Wall plate and horizontal bracket
3 Pantograph type arm (scissor arm)
4 X-ray source assembly (tubehead)
5 Collimator cone (Beam Limiting Device)

The timer is the control panel used to manage the exposure settings and to safely use the tubehead. It allows easy and clear selection, with the help of clear and visible signals, of the exposure settings, perform personal settings and display alarms of the device in case of incorrect operation or eventual failures.

The horizontal bracket it is available in 3 different lengths and represents the support for the scissor arm. The pantograph arm, being adjustable in height and depth, allows the precise positioning of the tubehead. The tubehead of the device contains the X-ray tube, the high voltage board and the high frequency generator. It is the component of the device which emits the X-rays.

The collimator cone represents the part of the device in contact with the patient and it allows the correct focal spot to skin distance, ensures the dimension, direction and centering of the X-ray beam.

x-mind dc can be used with conventional chemical films (D, E, F speed films), phosphor plates (PSP), RVG digital detectors (CCD or CMOS).

AI/ML Overview

The provided text outlines the 510(k) summary for the x-mind dc (and Owandy-RX DC) device, which is an extraoral source X-ray system intended for intra-oral radiographic exams. The core of the summary demonstrates substantial equivalence to a predicate device, Endograph DC (K130109), and a reference device, PHOT-X II, MODEL 303 (K042260).

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly present a table of "acceptance criteria" for the device in the sense of performance metrics like sensitivity, specificity, or accuracy for a diagnostic algorithm. Instead, it details the device's technical specifications and compliance with various international and national standards and regulations. The "acceptance criteria" here are implicitly the successful adherence to these standards, demonstrating safety and essential performance comparable to the predicate device.

To frame this in the requested format, we can list key technical specifications and their comparison to the predicate/reference devices, which serve as the "performance" verification. The ultimate "acceptance criterion" is the determination of substantial equivalence by the FDA.

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

The document does not specify a separate "test set" sample size in the context of a dataset for an AI algorithm. The performance evaluation is based on non-clinical bench testing and a comparison of technical specifications and compliance with standards.

For image quality, it mentions "Sample clinical images" were used, but the specific number is not provided.

The provenance of this data (e.g., country of origin, retrospective/prospective) is not detailed.

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

For the image quality assessment portion, the document states: "Sample clinical images, evaluated by a clinical expert, demonstrated diagnostic quality output when device is integrated with recommended cleared x-ray receptor(s)."

Number of experts: One ("a clinical expert")
Qualifications of experts: "clinical expert" - no further specific qualifications (e.g., years of experience, specialty like radiologist/dentist) are provided in the excerpt.

4. Adjudication Method for the Test Set

Not applicable. There was only one "clinical expert" involved in the image quality evaluation, so no adjudication method (like 2+1 or 3+1) was necessary or mentioned.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not performed. The study focuses on demonstrating substantial equivalence of the hardware device, not on the impact of an AI algorithm on human reader performance.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

Not applicable. The device is an X-ray unit, not an AI algorithm. The software component mentioned is for the device's operational control and safety, not for diagnostic interpretation. Therefore, a standalone performance study in the context of an AI algorithm is not relevant here.

7. Type of Ground Truth Used

For the overall device, the "ground truth" for demonstrating safety and effectiveness relies on:

Compliance with established international and national medical device standards (e.g., IEC 60601 series, ISO 10993-1, 21 CFR sections for diagnostic x-ray systems).
Demonstration of equivalent technical specifications compared to a legally marketed predicate device.
"Diagnostic quality output" from sample clinical images, assessed by a clinical expert. This expert assessment serves as the ground truth for image quality.

8. Sample Size for the Training Set

Not applicable. As the device is an X-ray unit and not an AI-powered diagnostic algorithm, there is no mention of a training set as would be used for machine learning.

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

Not applicable, as no training set for an AI algorithm is mentioned or relevant to this device's submission.

Both the subject and predicate device are X-ray equipment for dental intra-oral X-ray imaging, particularly they are extra-oral sources of X-rays intended to be used for producing diagnostic X-ray images of the teeth and adjacent oral structures.

Both devices are intended to be used by dentists, radiologists and other legally qualified health care professionals, and can be used both on adult and pediatric patients.

The type of X-ray detectors used for producing the X-ray images is clearly stated in the intended used of the subject device, the same kind of detectors is used also with the predicate device to obtain the radiographic exams.

Although worded differently, there are no differences between the subject device and the predicate device with respect to indications and intended use.

The subject and the predicate device are intra-oral X-ray units which use a high frequency constant potential (DC) generator for producing the X-rays, and some differences exist under the electrical data characteristics. These differences are just due to the different design specifications of the power supply board, which do not raise issue of safety and effectiveness. Both devices have been tested with the same performance testing and comply with the general requirements for basic safety and essential performance of medical electrical equipment and dental intra-oral X-ray equipment and have the same classification for the protection against the electrical shock.

The differences related to the tubehead characteristics are due to the different design specifications of the X-ray generation system, however both devices conform to the same safety and performance standards.

The above-mentioned differences between the proposed device and the predicate device do not raise new questions of safety and effectiveness.

Both the subject and the reference devices use a tubehead with the same technology, based on a high frequency constant potential (DC) generator for producing the X-rays. The design characteristics of the tubeheads are equivalent, as well as the selectable exposure time range is basically the same. Also, the X-ray tubes have the same anode material and same focal spot size.

This comparison supports the tubehead performance data of the subject device, which is as safe and effective as the legally marketed reference device.

Bench testing was performed to characterize device performance and resultant image quality when device is used/integrated with cleared x-ray receptor(s) meeting recommended specifications. Sample clinical images, evaluated by a clinical expert, demonstrated diagnostic quality output when device is integrated with recommended cleared x-ray receptor(s). The performance was demonstrated to be substantially equivalent to the predicate.
