The provided text describes the regulatory clearance of the ALPINION Medical Systems X-CUBE 70 and X-CUBE 90 diagnostic ultrasound systems. It does not contain information about acceptance criteria and a study proving a device meets these criteria in the context of an AI/ML-driven medical device, as the device itself is a diagnostic ultrasound system and not an AI/ML product.

However, the document lists several standards and regulations that the device conforms to to establish its safety and effectiveness relative to predicate devices. These can be interpreted as the high-level criteria for substantial equivalence.

Here's a breakdown of the information that is available, reframed to address your request where possible, and noting where information is explicitly not present for an AI/ML context:

1. A table of acceptance criteria and the reported device performance:

The document does not specify performance acceptance criteria in terms of metrics like sensitivity, specificity, or accuracy that would be typical for an AI/ML device study. Instead, it states the device's conformance to various safety and performance standards. The "New Technologies" are features of the ultrasound system itself, not standalone AI algorithms with performance metrics.

2. Sample size used for the test set and the data provenance:

• Not applicable / Not provided. The document states: "The subject of this premarket submission, X-CUBE 70 and X-CUBE 90, did not require clinical studies to support substantial equivalence." This means there was no specific clinical test set used to evaluate performance in the way an AI/ML device would be tested. The evaluation was based on conformance to engineering and safety standards and comparison to existing predicate devices.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

• Not applicable / Not provided. As no clinical study or test set for an AI/ML algorithm was conducted, there was no need for experts to establish ground truth in this context.

4. Adjudication method for the test set:

• Not applicable / Not provided. No clinical test set.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, if so, what was the effect size of how much human readers improve with AI vs without AI assistance:

• Not applicable / Not provided. This is not an AI-assisted device, so no such study was conducted.

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:

• Not applicable / Not provided. This is an ultrasound imaging system, not a standalone AI algorithm.

7. The type of ground truth used:

• Not applicable / Not provided. As no clinical evaluation study requiring ground truth was performed, this information is not available. The "ground truth" for this submission was based on the technical specifications and validated performance against established standards for ultrasound devices, as well as comparison to predicate devices.

8. The sample size for the training set:

• Not applicable / Not provided. This is not an AI/ML device.

9. How the ground truth for the training set was established:

• Not applicable / Not provided. This is not an AI/ML device.

In summary, the provided document is a 510(k) clearance letter for a diagnostic ultrasound system. It outlines the regulatory process for demonstrating "substantial equivalence" to existing devices, primarily through adherence to safety and performance standards and a comparison of technological characteristics. It is not a submission for an AI/ML product and therefore does not contain the specific types of acceptance criteria and study details you would expect for such a device.

Ask a specific question about this device

The X-CUBE 90 diagnostic ultrasound system is intended for use by, or by the order of, and under the supervision of, a licensed physician who is qualified for the evaluation of soft tissue and blood flow in the clinical applications of Fetal; Abdominal(renal & GYN/pelvic); Pediatric; Small Organ(breast, testes, thyroid); Neonatal Cephalic; Adult Cephalic; Trans-rectal; Trans-vaginal; Musculo-skeletal(Conventional); Musculo-skeletal(Superficial); Cardiac(adult& pediatric); Peripheral Vessel(PV); and Urology(including prostate).

And, in the imaging modes of 2D(B) mode; Harnonic mode(HAR); M mode; Anatomical M mode; Color Flow Doppler(CF) Mode; Power Doppler(PD) Mode; Directional PD mode; Pulsed Wave Doppler(PWD) Mode; Continuous Wave Doppler(CWD) Mode; High PRF Doppler mode; Tissue Doppler Imaging(TDI) Mode; 3D/4D mode. The X-CUBE 90 is intended to be used in a hospital or medical clinic.

X-CUBE 90 product is an ultrasound imaging system for medical diagnosis. This innovative system platform provides optimal patient diagnosis workflow with the wide flat panel display, ergonomic control panel with easy user interface, optimal image quality.

The provided document is an FDA 510(k) premarket notification for the Alpinion Medical Systems Co., Ltd. X-CUBE 90 ultrasound system. This type of submission is for demonstrating substantial equivalence to a legally marketed predicate device, rather than proving efficacy through clinical studies for novel devices.

Therefore, the acceptance criteria and study detailed here are focused on demonstrating that the new device (X-CUBE 90) performs equivalently to previously cleared predicate devices and complies with relevant safety and performance standards. It does not involve a traditional clinical study with patient data in the sense of an Artificial Intelligence (AI) device seeking de novo authorization or PMA.

Based on the provided text, here's an analysis of the acceptance criteria and the study that proves the device meets them:

1. A table of acceptance criteria and the reported device performance

The document does not explicitly present a "table of acceptance criteria" related to specific performance metrics for the ultrasound imaging capabilities beyond what is implied by the comparison to predicate devices and adherence to standards. Instead, substantial equivalence is demonstrated by a comparison of features, technical specifications, and compliance with recognized safety standards. The "performance" is implicitly deemed equivalent if these factors are comparable to or better than the predicate devices.

Here's a breakdown of the comparison presented in the "Determination of Substantial Equivalence: Comparison table with Predicate devices" on page 25:

Acceptance Criteria (Implicit from Substantial Equivalence):

The acceptance criteria for this 510(k) submission are implicitly defined by demonstrating that the X-CUBE 90 is "substantially equivalent" to legally marketed predicate devices (primarily K181277 E-CUBE 12). This means:

• Same intended use: The X-CUBE 90 has the same indications for use as the predicate device.
• Same technological characteristics: The device uses the same fundamental technology (ultrasound, various imaging modes and functions).
• No new questions of safety or effectiveness: Any differences in technological characteristics do not raise new questions of safety or effectiveness. This is primarily addressed through compliance with established safety and performance standards.

2. Sample size used for the test set and the data provenance

The document explicitly states: "The subject of this premarket submission, X-CUBE 90, did not require clinical studies to support substantial equivalence."

This means there was no dedicated clinical test set of patient data in the typical sense for demonstrating diagnostic accuracy or efficacy. The "study" for this submission primarily consists of non-clinical performance testing, compliance with international safety and performance standards, and comparisons of technical specifications and features to predicate devices.

Therefore, there is no sample size for an an imaging test set, and no data provenance relevant to patient-derived images.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

As there was no clinical study involving a test set of patient data to establish ground truth diagnoses, this information is not applicable.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable, as there was no clinical test set for which ground truth adjudication was required.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

No MRMC study was conducted. This device is an ultrasound system, not an AI-assisted diagnostic tool that would typically be evaluated for reader improvement.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable. This is not an AI algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

Not applicable, as no clinical ground truth was established for a test set. The "ground truth" for this type of submission is adherence to recognized performance standards and demonstrated technological equivalence to already cleared devices.

8. The sample size for the training set

Not applicable. This device is an ultrasound imaging system, not an AI/machine learning model whose performance is enhanced through training on a dataset.

9. How the ground truth for the training set was established

Not applicable, as there was no training set for an AI/machine learning model.

In summary, this 510(k) submission for the X-CUBE 90 ultrasound system primarily relies on non-clinical testing and comparison to predicate devices, rather than clinical studies with patient data and ground truth establishment, to demonstrate substantial equivalence. The "acceptance criteria" are met by demonstrating that the device's technical specifications, imaging modes, and overall performance fall within the established safety and effectiveness profile of already cleared ultrasound systems, and by proving compliance with relevant international and national medical device standards.

It specifically outlines the indications for use, comparison to predicate devices, and a summary of non-clinical tests.

This document focuses on the substantial equivalence of the new device (X-CUBE 70) to existing predicate devices, primarily based on technical characteristics and compliance with safety standards, rather than proving performance against specific acceptance criteria through a clinical or algorithmic study.

Therefore, most of the requested information regarding acceptance criteria, study details, sample size, ground truth, and expert reconciliation cannot be extracted from this particular document, as it describes a regulatory submission for a medical imaging device, not a performance study of an AI/algorithm-driven device.

However, I can provide information based on what is available in the document:

Acceptance Criteria and Device Performance (Not directly addressing AI/algorithmic performance)

This section is interpreted in the context of the device's functional and safety characteristics, as the document details its equivalence to predicate ultrasound systems, not an AI component with specific performance metrics.

Since this document is a 510(k) submission for an ultrasound system, not an AI or algorithm-driven device that requires clinical performance studies to demonstrate accuracy in a diagnostic task, the following points are generally not applicable or stated as not required by the document:

2. Sample size used for the test set and the data provenance: Not mentioned as no specific performance test set (in the context of AI/algorithm accuracy) was required. The substantial equivalence relies on technical specifications and safety profile similarity to existing devices.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for diagnostic accuracy (e.g., presence/absence of disease based on expert consensus) is not part of this type of submission for an ultrasound machine.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not applicable. This is an ultrasound imaging system, not an AI-assisted diagnostic tool being evaluated for reader improvement.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is a medical device (ultrasound system), not a standalone algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.): Not applicable. The "ground truth" here is the adherence to safety standards and performance characteristics comparable to predicate devices.
8. The sample size for the training set: Not applicable, as this is not an AI/ML device that requires a training set for a diagnostic algorithm.
9. How the ground truth for the training set was established: Not applicable.

Summary of Non-Clinical Tests (from document):
The device underwent non-clinical tests to assess biocompatibility, acoustic output, thermal, electrical, electromagnetic, and mechanical safety. It was found to conform to applicable medical device safety standards and voluntary standards (listed in the table above).

Summary of Clinical Tests (from document):
The document explicitly states: "The subject of this premarket submission, X-CUBE 70, did not require clinical studies to support substantial equivalence." This reinforces that the focus of this 510(k) submission is on technical and safety equivalence to predicate devices, not on a new clinical claim or an AI/algorithmic performance claim.
