More Information

Not Found

Yes
The device description explicitly states that the software uses "deep learning techniques" to analyze the radiographs, and the intended use also mentions using "deep learning techniques". Deep learning is a subset of machine learning.

No
The device is designed to aid in the analysis of bone age assessment by quantifying bone age from radiographs, not to treat or alleviate a medical condition.

Yes

The device aids in the analysis of bone age assessment, which is a diagnostic activity. It helps quantify bone age from radiographs, even though the results should not be solely relied upon for diagnostic decisions.

Yes

The device description explicitly states "The device is a software designed to aid the quantification of bone age". There is no mention of any accompanying hardware components being part of the device itself.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: The EFAI BONESUITE XR BONE AGE PRO ASSESSMENT SYSTEM analyzes radiographic images (X-rays), which are external imaging data, not biological samples taken from the body.
  • Intended Use: The intended use is to "view and quantify bone age from 2D Posterior Anterior (PA) view of left-hand radiographs," which is an image analysis task, not a diagnostic test performed on a biological sample.

Therefore, while this device is a medical device that aids in diagnosis, it falls under the category of medical image analysis software rather than an In Vitro Diagnostic.

No
The letter does not explicitly state that the FDA has reviewed and approved or cleared a PCCP for this specific device.

Description of the training set, sample size, data source, and annotation protocol

During the process of model development, a total of 26,222 cases were retrospectively collected from Taiwan and the United States (U.S.). These cases were subsequently divided into training and testing datasets, consisting of 23.578 and 2.644 cases, respectively. Ground-truthing was the average of the bone age assessment independently done by three board-certified radiologists.

Description of the test set, sample size, data source, and annotation protocol

The test data comprised 600 cases aged 2-16 years, acquired from 27 locations across multiple states and multiple clinical organizations in the United States. The study population contained 50.0% males and 50.0% females, with a mean chronological age of cases was 9.2 years old and 120 cases in each three-year age interval. The race or ethnicities of cases include White, Hispanic, Black, Asian, Multiple, etc. The X-Ray scanner manufacturers of images include Samsung Electronics, Carestream Health, Kodak, GE Healthcare, Siemens, Konica Minolta, etc. None of the cases was used as part of the EFAI BAPXR model training or development. The ground truth (GT) was generated through a truthing process based on the current standard of care, with the addition of multiple checkpoints to ensure consistency and consensus among four U.S. board-certified expert radiologists reviewing the radiographs when comparing them to the Greulich-Pyle Atlas.

Device Description 4.

The device is a software designed to aid the quantification of bone age for patients between 2 to 16 years old. The software uses deep learning techniques to analyze posterior-anterior (PA) radiographs of the left-hand according to the Greulich-Pyle (GP) method.

Intended User Population

The intended users of EFAI BAPXR are pediatric radiologists.

When a clinician accesses the patient radiographs in a picture archiving and communication system (PACS) client or a workstation, both the EFAI BAPXR quantification and the original unaltered radiographs are available in the same patient study, allowing for concurrent reading.

EFAI BAPXR is an adjunct tool and is not intended to replace a clinician's review of the radiograph or his or her clinical judgment. Clinicians must not use the software generated output as the primary interpretation.

Intended Patient Population

The target population of the device are patients between 2 and 16 years old that require a bone age assessment.

Description of output

The algorithm outputs a standard JSON message, to ensure consistent interpretation and simple integration across systems. The result contains structured information in regards to the estimated bone age in years and the data can be transferred and processed by RIS/HIS/PACS and other workstations.

Performance Data 7.

Performance of the EFAI BAPXR has been evaluated and verified in accordance with software specifications and applicable performance standards through software verification and validation testing. Additionally, the software validation activities were performed in accordance with IEC 62304:2006/A1:2016 - Medical device software - Software life cycle processes, in addition to the FDA Guidance documents, "Content of Premarket Submissions for Device Software Functions" and "Cybersecurity in Medical Devices: Quality System Considerations and Content of Premarket Submissions."

To establish the performance of EFAI BAPXR, the performance was validated by nonclinical and clinical tests.

Nonclinical Tests

During the process of model development, a total of 26,222 cases were retrospectively collected from Taiwan and the United States (U.S.). These cases were subsequently divided into training and testing datasets, consisting of 23.578 and 2.644 cases, respectively.

An internal validation test was conducted to assess the performance of the EFAI BAPXR. Ground-truthing was the average of the bone age assessment independently done by three board-certified radiologists.

Overall, the Deming regression analysis result showed a good correlation between GT and EFAI BAPXR's output. The intercept of the regression line was -0.06 with a 95% CI of [-0.09, -0.03]

and the slope was 1.00 with a 95% CI of [1.00. 1.01]. By confirming that the Cls of both measures fall within the highest acceptable bias.

Clinical Tests

EFAI conducted a standalone performance study with the proposed device EFAI BAPXR with a pre-determined primary endpoint and performance goal to evaluate the software's performance on left-hand X-ray images in PA view. The test data comprised 600 cases aged 2-16 years, acquired from 27 locations across multiple states and multiple clinical organizations in the United States. The study population contained 50.0% males and 50.0% females, with a mean chronological age of cases was 9.2 years old and 120 cases in each three-vear age interval.The race or ethnicities of cases include White, Hispanic, Black, Asian, Multiple, etc. The X-Ray scanner manufacturers of images include Samsung Electronics, Carestream Health, Kodak, GE Healthcare, Siemens, Konica Minolta, etc. None of the cases was used as part of the EFAI BAPXR model training or development.

The study design measured the performance of EFAI BAPXR against the ground truth (GT) from four U.S. board-certified expert radiologists. As shown in the following figure A) for the ground truthing workflow, the ground truthing was generated through the truthing process based on the current standard of care, with the addition of multiple checkpoints to ensure consistency and consensus among all readers reviewing the radiographs when comparing them to the Greulich-Pyle Atlas.

Image /page/7/Figure/5 description: The image shows a flowchart describing a ground truthing workflow. The workflow is divided into four phases: Bone Age Assessment, Consensus Via Grading, Majority Voting, and Final Adjudication. Each phase involves a decision-making process based on criteria such as differences in bone age assessments, grades, and votes. The flowchart outlines the steps to determine the ground truth (GT) based on the readers' assessments.

Image /page/8/Picture/0 description: The image contains a logo for a company called "EVER FORTUNE.AI". The logo consists of a stylized human figure with a green globe-like head, connected by lines and dots, and a teal body. To the right of the figure, the word "EVER" is written in large, teal letters, with "FORTUNE.AI" written in smaller letters below it, also in teal.

The primary endpoint was the intercept and slope of a Deming regression between GT and EFAI BAPXR's output. The acceptance criteria were met if both the intercept and slope of the regression line had fallen within the range of the highest acceptable bias.

The observed results of the standalone performance validation study demonstrated that EFAI BAPXR can provide bone age assessments with satisfactory results including over 88% of the cases with a difference less than 0.5 years between GT and EFAI BAPXR's output. The intercept of the Deming regression result was -0.07 with a 95% Confidence Interval (95% CI) of [-0.13, -0.01] and slope of 1.00 with a 95% CI of [0.99, 1.00]. Overall, the device performance met the performance goal compared with the GT, thus reaching the primary endpoint. In addition, as shown in the following Bland-Altman plot (Figure B), the 95% limits of agreement (red solid lines) for bone age assessment between GT and EFAI BAPXR's output ranged from -0.517 to 0.743 (with corresponding CIs in gray dashed lines), indicating high consistency.

Image /page/8/Figure/3 description: This image is a Bland-Altman plot of the EFAI BAPXR. The x-axis represents the average of GT and EFAI BAPXR's output in years, ranging from 0 to 20. The y-axis represents the difference between GT and EFAI BAPXR's output in years, ranging from -4 to 4. The plot shows a scatter of points around the zero line, with two dashed lines indicating the limits of agreement.

As shown in the table below, we also evaluated the performance of EFAI BAPXR in various clinical subgroups to see if these factors systematically affect the device performance, including gender, age, race or ethnicity, clinical organization, X-ray manufacturer, input image with radiologic findings (including epiphyseal, finger, carpal/ metacarpal, radius/ ulna, others, and multiple), and image quality issues (including poor image quality, poor position, foreign body, artifact, and multiple).

Image /page/10/Picture/0 description: The image shows the logo for Ever Fortune AI. The logo consists of a teal-colored icon on the left, resembling a person with a globe as their head. To the right of the icon, the words "EVER" and "FORTUNE.AI" are written in teal. The logo appears to be for a company that specializes in artificial intelligence.

Overall, we found the device performs consistently and reliably under these circumstances, this concludes the performance demonstrated that the EFAI BAPXR device is as safe and effective as the predicate device Medo Aria.

Safety & Effectiveness 8.

EFAI BAPXR has been designed, verified and validated in compliance with 21 CFR, Part 820.30 requirements. The device has been designed to meet the requirements associated with ISO 14971:2019 Medical devices - Application of risk management to medical devices. The EFAI BAPXR performance has been validated using retrospective data from case data and through the use of Reader comparison analysis.

Substantial Equivalence 9.

The EFAI BAPXR has minor differences compared to the predicate device. These differences are related to the Intended Use and to the Quantitative Analysis features.

The Medo Aria predicate is intended to quantify ultrasound images to support diagnosis of development dysplasia of the hip (DDH) based on Graf. The EFAI BAPXR is intended to quantify bone age based on an image atlas. Although the intended uses are different, the principle of operation is the same as both devices use artificial intelligence algorithms to view and quantify radiograph images and provide results based on an established reference or standard. Both devices have similar risks and are mitigated by similar special controls. Both devices rely on labeling and clinical performance testing as mitigations to address risks related to the use of the devices. Therefore, although the intended uses are not exactly the same, the risks and technology used by both devices are the same and are mitigated similarly and thus the proposed device does not raise new questions of safety or efficacy as no new risks are introduced.

The predicate device consists of a user interface in which end users are able to interact with images using typical image navigation and manipulation tools, including landmark placement. The proposed device does not consist of a typical user interface which allows users to interact with images using typical image navigation and manipulation tools, including landmark placement. However, this difference does not raise new questions of safety or efficacy and does not add new or significant risk to the device as the differences are workflow related and the end users are able to still access the original image to interpret the image according to standard practices.

10. Conclusion

Based on the information submitted in this premarket notification, and based on the indications for use, technological characteristics, and performance testing, the EFAI BAPXR raises no new questions of safety and effectiveness and is substantially equivalent to the predicate device in terms of safety, efficacy, and performance.
