The DICOM Video software package is intended for use by authorized personnel to acquire individual or sequences of images and to allow the user to input patient demographics related to the image. The device transforms imaging studies to DICOM format before they are made available to other locations in the network. The DICOM Video is indicated to receive studies in various digital formats (text, still images and video) or digitized video signals from acquisition host devices. The device operations include capturing the data, recording, storing, editing and transferring it to the clinic PACS as DICOM files.

The DICOM Video is a software package, which is installed in an Off - The - Shelf Host PC. The device is interfaced and configured to a hospital Local Area Network (LAN). The DICOM Video receives patients' list from the Hospital Modality Work List (MWL ) server and digital files input data (in text, images or video formats). The device records the received data, stores it, transfers the studies into standard DICOM files, and transmits the DICOM files via the LAN to the Hospital PACS. The DICOM Video can be interfaced to a Host Acquisition Device in order to receive analog video signals. The data is digitized, stored, optionally edited, transferred into standard DICOM files, and transmitted as DICOM files via the LAN to the Hospital PACS. The device can also retrieve DICOM studies from the PACS and display them on the user screen.

Here's a breakdown of the acceptance criteria and the study information for the DICOM Video device, based on the provided document:

1. Table of Acceptance Criteria and Reported Device Performance

The provided document (K132183) for the DICOM Video device does not explicitly list "acceptance criteria" in a quantitative or pass/fail table as one might expect for a diagnostic AI device. Instead, the performance is described in terms of compliance with standards and successful functionality testing.

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

The document does not specify a numerical sample size for any test set or provide details on data provenance (e.g., country of origin, retrospective/prospective). The testing described is functional and compliance-based, rather than clinical efficacy studies involving patient data.

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

Not Applicable. The device is a "Medical Image Digitizer" (a software package that converts various image and video formats into DICOM files and manages them). It does not perform diagnostic interpretations of medical images that would require expert consensus ground truth. Its "ground truth" would be related to the accurate and complete conversion and transfer of data according to DICOM standards and its stated functionalities.

4. Adjudication Method for the Test Set

Not Applicable. As explained above, this device does not involve diagnostic interpretations requiring an adjudication method by experts.

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

No. The document explicitly states: "Clinical Data: Clinical data is not included." An MRMC study assesses the impact of a device on human reader performance, which requires clinical data and human interpretation. This device is a data processing and management tool, not a diagnostic aid for human readers.

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

Yes, in essence. The "Bench data" described indicates standalone performance testing of the software itself: "The device performance has been verified by testing the software with respect to predefined software test plan." The "device validation" in an end-user environment further confirms its performance without explicitly relying on human interpretation of diagnostic findings, but rather on its functional execution.

7. Type of Ground Truth Used

The "ground truth" for this device's performance is based on:

• Compliance with specifications and standards: Adherence to NEMA PS 3.1 - 3.20 (2011) DICOM set.
• Functional correctness: Output meeting "design input" and supporting "indications for use" as demonstrated by predefined software test plans and end-user environment testing.
• Regulatory compliance: Conformance to 21CFR 820.30 regulations.

8. Sample Size for the Training Set

Not Applicable. This device is a pre-AI era software for data digitization and management. It is not an AI/Machine Learning model that would typically have a "training set" in the context of learning patterns from data. Its functionality is rule-based and standard-compliant.

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

Not Applicable. As this is not an AI/Machine Learning device that requires a training set, the concept of establishing ground truth for a training set does not apply.

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

Not applicable. This device is a film digitizer; it does not utilize a "training set" in the context of machine learning.

Study Proving Device Meets Acceptance Criteria:

The document states: "VIDAR conducts extensive performance testing and the test results demonstrate the device meets the requirements for its intended use."

However, the specific details of this "extensive performance testing" are not provided in this 510(k) summary. The submission relies on claiming substantial equivalence to the predicate device (VIDAR TeleradPRO film digitizer, K102476) rather than providing a detailed report of a new clinical or technical performance study for the TeleradPRO Edge and HD-CCD. The conclusion states: "In terms of intended use, function, safety, operating environmental conditions and effectiveness of the TeleradPRO Edge and TeleradPRO Edge HD-CCD it is determined to be substantially equivalent to the predicate device used for this application." This implies that the 'study' demonstrating acceptance criteria is primarily a comparison against the predicate device's established performance and specifications, along with internal technical verification tests.

However, it does not contain detailed information about specific acceptance criteria or an in-depth study that proves the device meets those criteria in a quantitative manner as typically expected for medical device performance studies.

The document primarily focuses on establishing substantial equivalence to a predicate device, which often relies on demonstrating similar technological characteristics and intended use, rather than presenting a novel clinical study with detailed performance metrics against predefined acceptance criteria.

Based on the provided text, here's the information that can be extracted, and where information is missing:

1. Table of Acceptance Criteria and Reported Device Performance

Missing Information: Specific quantitative acceptance thresholds for DMAX, medical OD range linearity, and noise are not provided, nor are detailed test results demonstrating compliance against these thresholds. The document states "VIDAR conducts extensive performance testing and the test results demonstrate the device meets the requirements for its intended use" but does not elaborate on the specific tests or their outcomes beyond the summary characteristics.

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

It suggests that the testing was primarily to demonstrate the device's technical specifications and substantial equivalence, not necessarily a clinical or reader study with a specific test set of images.

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

This information is not provided in the document. As no clinical or reader study with a "test set" and "ground truth" established by experts is described, this information is not applicable. The device is a digitizer, not an AI diagnostic tool, so "ground truth" would relate to the fidelity of the digitization process itself, not an interpretation of medical images.

4. Adjudication Method for the Test Set

This information is not provided in the document. See point 3 above.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size of How Much Human Readers Improve with AI vs. Without AI Assistance

No MRMC study was done, nor is it relevant given the device is an X-ray film digitizer, not an AI diagnostic tool designed to assist human readers. The document does not mention any AI components.

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

The document describes "Performance Testing" and "Bench Testing" which would likely be standalone evaluations of the digitizer's technical specifications (e.g., resolution, DMAX, linearity). However, details of these studies are not provided beyond the summary characteristics listed in Section 1.

7. The Type of Ground Truth Used

Given that the device is a digitizer, the "ground truth" for its performance would typically involve comparing the digitized image to the original film's characteristics or a known standard.

Ask a specific question about this device

The Medi-6000 consists of a transparency film digitizer and paper CCD scanner that is used to digitize radiographs or X-ray film as well as paper reports or doctor's orders. When the Medi-6000 is used to digitize radiographic films, the digital image is intended for use in primary, secondary and over reading applications. This device is not to be used for primary image diagnosis in mammography. The target users of the device are medical professionals or trained staffs.

The Medi-6000 is a digitizer that can easily transfer x-ray films into a digital format for patients, hospitals, and office records. It can capture details in bright and dark areas of x-ray films and provide the medical professionals a convenient method to digitize the roentgenogram for the electric data storage.

The provided 510(k) summary for the Microtek International, Inc. Medi-6000 Medical Image Digitizer (K091288) contains limited information regarding detailed acceptance criteria and a specific study proving the device meets them. It primarily focuses on demonstrating substantial equivalence to predicate devices based on technological characteristics and intended use.

Here's an analysis based on the available text:

1. Table of Acceptance Criteria and Reported Device Performance:

The document mentions specific technological characteristics, which act as de facto performance criteria for comparison with predicate devices. However, explicit "acceptance criteria" for a study are not presented in a formal table or detailed manner. The performance criteria are implied by the device's specifications and the comparison to predicate devices.

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

The document does not explicitly state a sample size for a test set. There is no mention of a clinical or image-based study with a test set of images. The performance testing section states "The performance testing results for the Medi-6000 digitizer demonstrated that the device meets its intended use specifications," but it doesn't describe the methodology, sample selection, or data provenance (e.g., country of origin, retrospective/prospective nature of data).

3. Number of Experts Used to Establish Ground Truth and Qualifications:

The document does not mention using experts to establish ground truth for any test set, as no specific image-based study is described. The assessment appears to be based on physical device specifications and comparison to predicate devices.

4. Adjudication Method for the Test Set:

Since no test set or image-based study is described, there is no information provided on any adjudication method.

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

The document does not mention any MRMC study. The device is a digitizer, and the regulatory filing focuses on its ability to convert physical films to digital images, not on its impact on human reader performance in interpreting those images.

6. Standalone Performance Study:

The document discusses "Performance Testing" which indicates a standalone assessment of the digitizer's capabilities (e.g., resolution, Dmax, grayscale). This implies a standalone evaluation of the algorithm/device's ability to digitize images according to its specifications. However, the details of this testing (e.g., number of films digitized, specific tests performed) are very brief. It states: "The performance testing results for the Medi-6000 digitizer demonstrated that the device meets its intended use specifications and therefore meets the requirements necessary for its intended use as a component of a PAC or Teleradiology system." This suggests internal testing was conducted on the device's technical performance characteristics.

7. Type of Ground Truth Used:

For the performance specifications (resolution, Dmax, grayscale), the "ground truth" would likely be technical measurements against established industry standards or calibrated test patterns. For example, resolution would be measured using line pair patterns, and Dmax would be measured with calibrated densitometers. There is no mention of expert consensus, pathology, or outcomes data as ground truth for this device, which is primarily a hardware digitizer.

8. Sample Size for the Training Set:

The document does not mention a training set as this device is a film digitizer, not an AI/machine learning algorithm that requires training data.

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

This question is not applicable as there is no training set for a film digitizer.

Summary of Findings:

The 510(k) summary for the Microtek Medi-6000 Medical Image Digitizer is primarily a submission for a hardware device seeking substantial equivalence to existing predicate film digitizers. The "performance testing" described is focused on the device's technical specifications (resolution, dynamic range, grayscale) rather than a clinical study evaluating diagnostic accuracy or reader performance using digitized images. Therefore, many of the typical elements expected for an AI/CADe device study (like test set size, expert ground truth, MRMC studies, or training sets) are not present or not relevant in this document. The acceptance criteria are essentially the device's specifications aligning with or improving upon those of the predicate devices.

The NAI Tech Products Medical Digital Recorder is intended for use in Radiology applications to capture and digitize images and record them to single or multiple in the form of CD (Compact Disc) or DVD (Digital Video Disc).

Medical Digital Video Recorder

The provided text is a 510(k) clearance letter from the FDA for a "Medical Digital Video Recorder." It does not contain the specific technical details about acceptance criteria or a study proving those criteria are met for the device itself.

The document states that the device is "intended for use in Radiology applications of capture and digitize video images and record them to single or multiple media in the form of CD (Compact Disc) or DVD (Digital Video Disc)." This describes the function, but not performance metrics or how performance was validated.

Therefore, I cannot provide the requested information based solely on the text provided. The acceptance criteria and the study results would typically be contained within the 510(k) submission document itself, which is not fully included here.

However, I can deduce what types of information would typically be present in such a study for this kind of device, if it were available:

• Acceptance Criteria: For a medical digital video recorder, common acceptance criteria would likely revolve around image quality, recording accuracy, data integrity, and compliance with relevant standards. Examples might include:

  • Resolution preservation (e.g., recorded image resolution matches input resolution).
  • Frame rate integrity (e.g., no dropped frames during recording).
  • Color accuracy (e.g., recorded colors are perceptually similar to input).
  • Absence of artifacts (e.g., compression artifacts, noise introduction).
  • Successful recording and playback rate (e.g., 99.9% successful recordings).
  • Data permanence on recorded media (e.g., ability to reliably retrieve data after X years).
  • Compliance with DICOM or other relevant medical imaging standards for interoperability.

• Study Design (Hypothetical, based on device type):

  • Device Performance: Assessment would involve recording various medical video sources (e.g., fluoroscopy, endoscopy, ultrasound, etc.) and evaluating the output against the input.
  • Ground Truth: For a device that digitizes and records, the "ground truth" would likely be the original analog or digital video signal itself, as observed on a calibrated monitor or measured electronically.
  • "Experts": For image quality assessment, radiologists, clinicians, or imaging scientists might subjectively evaluate recorded media, or objective metrics could be used. For data integrity, technical experts would verify bit-for-bit accuracy.
  • Sample Size: This would depend on the statistical power needed to demonstrate compliance with the acceptance criteria. For a variety of medical video types and recording durations.
  • Data Provenance: Could be a mix of synthetic data, clinical data from various institutions (potentially retrospective), and test patterns.
  • Adjudication Method: If subjective image quality assessment was used, a consensus method (e.g., 2+1 or 3+1) among experts would be common.
  • MRMC Comparative Effectiveness: Highly unlikely for this type of device. An MRMC study assesses the impact of a diagnostic tool on human reader performance. A video recorder's primary function is data capture and storage, not diagnostic interpretation. It doesn't "improve" human readers in the same way an AI diagnostic algorithm might.
  • Standalone Performance: Yes, the performance would be standalone – the algorithm / device would be judged on its ability to accurately capture and store the video, without direct human-in-the-loop interpretation being part of its primary function.
  • Training Set: For a digital video recorder, extensive "training" in the AI sense is unlikely. The device likely relies on established digital signal processing, compression algorithms, and hardware. If there were any adaptive components, the "training data" would be technical specifications and various video inputs used for calibration and testing during development.
  • How Ground Truth for Training Set was Established: Again, not applicable in the AI sense. Ground truth for calibration and testing would be established by comparing processed video to known input video signals, using objective metrics.

In summary, the provided document is a regulatory clearance letter, not a technical report detailing the performance study. To get the specific information requested, one would need access to the actual 510(k) submission and its supporting technical documentation.
