The ClearVision ExamVue Flat Panel detector is not indicated for use in mammography.

The ClearVision ExamVue Flat Panel Detector consists of a line of 3 different models of solid state x-ray detectors, of differing size and characteristics, designed for use by radiologists and radiology technicians for the acquisition of digital x-ray images. The ClearVision ExamVue Flat Panel Detector captures digital images of anatomy through the conversion of x-rays to electronic signals, eliminating the need for film or chemical processing to create a hard copy image. The ClearVision ExamVue Flat Panel Detector incorporates the ExamVueDR software, which performs the processing, presentation and storage of the image in DICOM format.

All models of the ClearVision ExamVue Flat Panel Detector use aSi TFTD for the collection of light generated by a CsI scintillator, for the purpose of creating a digital x-ray image. The three available models are:

• a. A 14x17in (35x43cm) tethered cassette sized panel
• b. A 14x17in (35x43cm) wireless cassette sized panel with automatic exposure detection
• c. A 17x17in (43x43cm) tethered panel for fixed installations.

The provided document is a 510(k) premarket notification for a medical device called the "ClearVision ExamVue Flat Panel Detector". This document primarily focuses on establishing substantial equivalence to previously cleared predicate devices rather than proving a device meets specific clinical acceptance criteria through a dedicated study.

Therefore, many of the requested elements for describing specific acceptance criteria and study details cannot be fully extracted from this document. The document presents laboratory performance data and mentions "clinical images" but does not detail a formal clinical study with specific acceptance criteria as one would find in a clinical trial.

However, based on the information provided, here's what can be inferred and stated:

Acceptance Criteria and Reported Device Performance

The document does not specify formal clinical acceptance criteria (e.g., sensitivity, specificity, accuracy targets that the device must meet for a specific diagnostic task). Instead, the "acceptance criteria" are implied by demonstrating substantial equivalence to predicate devices through technical specifications and performance characteristics, as well as indications for use and safety. The primary "study" proving the device meets these (implied) acceptance criteria is the comparison of its technical specifications and general performance to those of the predicate devices.

Study Details

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

   • The document mentions "Clinical images were provided" and "clinical testing of the hardware" but does not specify a separate "test set" in terms of number of cases/patients used to evaluate performance against specific diagnostic endpoints or ground truth.
   • Data provenance (country of origin, retrospective/prospective) is not specified for these "clinical images". The application is from JPI Healthcare Co., LTD, based in Seoul, South Korea, so the data may originate from there, but this is not explicitly stated.

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

   • This information is not provided. The "clinical images" and "clinical testing" are used to show the device "works as intended" in addition to laboratory data, rather than for a formal evaluation against expert-derived ground truth for diagnostic accuracy.

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

   • Not applicable as a formal adjudication process for a diagnostic performance test set is not described.

4. 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 comparative effectiveness study is mentioned. This device is an X-ray detector, not an AI diagnostic algorithm, so "human readers improve with AI vs without AI assistance" is not applicable in this context.

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

   • The device itself is a hardware component (Flat Panel Detector) and not an "algorithm" in the sense of an AI/CAD system. Its performance is assessed standalone through technical specifications and image quality metrics (DQE, MTF, Limiting Resolution) in a laboratory setting, and "clinical images" are used for qualitative assessment.

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

   • For the "clinical images" mentioned, the type of ground truth is not specified. Given the context, it's likely qualitative assessment by radiologists that the images are of diagnostic quality for their intended use, rather than a comparison to a definitive clinical ground truth for specific pathologies. For the technical specifications (DQE, MTF, Limiting Resolution), these are objective measurements derived from physical phantom or test object images, not clinical ground truth.

7. The sample size for the training set:

   • This device is hardware; it does not have a "training set" in the context of machine learning algorithms. The associated software (ExamVueDR) processes and presents images, but details about its own training data (if any for image processing algorithms) are not provided here.

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

   • Not applicable, as this is hardware and not a machine learning algorithm.

Ask a specific question about this device

ClearVision is intended to be used by dentists and other qualified professionals for producing diagnostic x-ray radiographs of dentition, jaws and other oral structures.

ClearVision is a digital imaging system for dental radiographic application. The product is to be used for routine dental radiographic examinations such as bitewings, periapicals, etc. Two different sized sensors (size 1 and size 2) are utilized to image different anatomy and for different patient sizes. The CMOS sensor connects directly to a USB connection in a PC without the need for an intermediate electrical interface. ClearVision works with a standard dental intraoral x-ray source without any connection to the x-ray source. ClearVision captures an image automatically upon sensing the production of x-ray and after the x-ray is complete, transfers the image to an imaging software program on the PC. Disposable sheaths are used with each use to prevent cross-contamination between patients.

This provides an analysis of the provided text regarding the ClearVision Digital Sensor System.

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria for the ClearVision Digital Sensor System are derived from its comparison to predicate devices (Schick CDR and Gendex GXS-700) and general engineering requirements. The reported device performance indicates equivalency or superiority to these predicates.

Note: The document states "found to be equivalent to the Gendex GXS-700 in all three tests and superior to the Schick sensor in all three imaging tests," implying that the performance level of the GXS-700 served as the primary benchmark for "equivalency" for the ClearVision's imaging performance.

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

The document does not explicitly state a specific numerical sample size for the test set used in the imaging performance comparison. It mentions "each sensor to image a line pair phantom, an aluminum step wedge, and a tooth phantom." This implies at least one instance of imaging each of these phantoms per sensor.

The data provenance is not explicitly stated. Given the context of a 510(k) submission and the nature of the tests (imaging phantoms), it is highly likely that this was prospective data generated in a controlled laboratory or engineering setting, likely within the United States where the company is based. There is no mention of patient data or clinical trials.

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

The document does not describe the use of human experts to establish ground truth for the test set. The tests performed ("imaging a line pair phantom, an aluminum step wedge, and a tooth phantom") are objective, physical measurements against established standards for image quality and resolution (e.g., line pairs, step wedge density differences). Therefore, the "ground truth" would be inherent in the physical phantoms themselves and the objective metrics used to evaluate the images.

4. Adjudication Method for the Test Set

No adjudication method is described, as the evaluation methods appear to be objective and quantitative (e.g., measuring line pairs, density differences). Human interpretation or consensus for ground truth was not mentioned or implied.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size

No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. The study described is a technical performance comparison of the device against predicate devices using physical phantoms, not a clinical study involving human readers or patient cases. Therefore, there is no effect size related to human reader improvement with or without AI assistance.

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

Yes, the described imaging performance comparison of the ClearVision sensor is a standalone assessment. The evaluation focuses solely on the device's ability to capture and produce images from phantoms, without any involvement of a human interpreter in the loop for diagnostic decision-making during the testing process. The device itself is a digital sensor, not an AI algorithm.

7. The Type of Ground Truth Used

The ground truth used for the imaging performance tests was objective, physical standards provided by the phantoms:

• Line pair phantom: Provides known spatial frequencies (lines per millimeter) to assess resolution.
• Aluminum step wedge: Provides known material thicknesses/densities to assess contrast and dynamic range.
• Tooth phantom: Likely provides a realistic but standardized representation of dental anatomy to assess overall image quality and detail capture.

8. The Sample Size for the Training Set

The document describes a physical medical device (a digital X-ray sensor), not an AI/machine learning algorithm. Therefore, there is no training set in the context of an algorithm or AI model. The device's "training" or development would have involved engineering design, prototyping, and iterative testing to meet specifications, but not a dataset for training an algorithm.

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

Since this is a physical device and not an AI algorithm, the concept of a "training set" and establishing ground truth for it is not applicable. The device's "ground truth" during its development would have been established through engineering specifications, material properties, and performance targets derived from scientific principles and a comparison to existing technologies.

Ask a specific question about this device

The ClearVision nuclear medicine imaging system is intended for use as a diagnostic imaging device to acquire and process gated and non-gated Single Photon Emission Computed Tomography (SPECT) images.

Used with appropriate radiopharmaceuticals, the ClearVision system produces images that depict the anatomical distribution of radioisotopes within the myocardium.

The ClearVision Nuclear Medicine Imaging System acquires and processes cardiac data including gated and non-gated Single Photon Emission Computed Tomography (SPECT) studies. After completion of an acquisition, the operator can select the resulting acquisition data file to generate both qualitative and quantitative results for review by a physician. This includes processing using Release 5.6 of Segami Corporation's Mirage processing software that was previously cleared under 510(k) number K043441 dated 13-January-2005.

The acquisition system consists of either a single or dual small field-of-view detectors with each mounted on top of a tower that contains system electronics. To support the acquisition of SPECT data, the patient chair rotates up to 360 degrees in either clockwise or counterclockwise direction.

Prior to a patient scan, the following system features are used to ensure the myocardium is centered within each detector's field of view (FOV):

• . Each tower can be moved horizontally along rails mounted to the floor plate.
• . The patient chair seat pan can be moved side-to-side.
• Vertical and a horizontal beam lasers are mounted to side of detector.

The ClearVision system's compact footprint and small FOV detector are specifically designed for placement in a facility lacking adequate floor space for a typical nuclear medicine imaging system.

The provided document is a 510(k) summary for the GVI Medical Devices ClearVision Nuclear Imaging System. It focuses on demonstrating substantial equivalence to a predicate device rather than presenting a detailed study with acceptance criteria and performance metrics for the ClearVision system itself.

Therefore, much of the requested information regarding acceptance criteria, specific study designs, sample sizes, expert qualifications, and ground truth establishment is not available in this document. The document describes a comparison of features and performance characteristics to a predicate device (Digirad Cardius 1 XPO and Cardius 2 XPO SPECT Imaging Systems, K070542) to establish substantial equivalence.

Here's a breakdown of what can be extracted and what is not available based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state "acceptance criteria" but rather presents a "Feature Comparison Summary" to demonstrate substantial equivalence to the predicate device. The performance characteristics listed are NEMA (National Electrical Manufacturers Association) standards, which are common for SPECT systems and implicitly serve as performance benchmarks.

This 510(k) summary does not contain the information required to answer your request.

Here's why:

• Acceptance Criteria and Device Performance: The document does not describe specific performance-based acceptance criteria (e.g., a certain flow rate, cleaning effectiveness percentage) or present data from a study demonstrating the device meets such criteria. Instead, it focuses on substantial equivalence to a predicate device based on features and intended use.
• Study Details (Sample Size, Provenance, Ground Truth, Training Set): There is no mention of a study involving a test set, training set, or the establishment of ground truth. The submission is a regulatory comparison against a predicate device, not a performance study.
• Expert Review/Adjudication: Since no performance study (like a clinical trial or algorithm evaluation) is presented, there's no information about experts used for ground truth, their qualifications, or adjudication methods.
• MRMC or Standalone Studies: The document does not discuss multi-reader multi-case comparative effectiveness studies or standalone performance studies. The KSEA Clearvision is a physical pump device, not an AI or imaging-based diagnostic tool that would typically undergo such studies.

In summary, this 510(k) pertains to a medical device's regulatory clearance based on substantial equivalence, rather than a detailed performance study with acceptance criteria.
