For In Vitro Diagnostic Use

Sectra Digital Pathology Module device is a software intended for viewing and management of digital images of scanned surgical pathology slides prepared from formalin-fixed paraffin embedded (FFPE) tissue. It is an aid to the pathologist to review and interpret these digital images for the purposes of primary diagnosis.

Sectra Digital Pathology Module is not intended for use with frozen section, cytology, or non-FFPE hematopathology specimens.

It is the responsibility of the pathologist to employ appropriate procedures and safeguards to assure the validity of the interpretation of images using Sectra Digital Pathology Module.

Sectra Digital Pathology Module is intended for use with Leica's Aperio AT2 DX scanner and Dell MR2416 monitor.

Device Description

Sectra Digital Pathology Module is a software-only device running under the Microsoft Windows operating system for displaying and manipulating digital pathology images (scanned slides) obtained from the Aperio AT2 DX scanner.

Sectra Digital Pathology Module may only be used in combination with Sectra PACS which consists of Sectra Workstation (K081469) and Sectra Core (identified as a Class I exempt by the FDA in 2000).

The Sectra Pathology Import Server (SPIS) is used for importing digital pathology images (scanned slides) from the scanner. These images are viewed and manipulated by end users in the Pathology Image Window which is displayed on the Sectra Workstation IDS7 (using the Dell MR2416 monitor).

AI/ML Overview

Here's an analysis of the acceptance criteria and the study conducted for the Sectra Digital Pathology Module, extracted from the provided text:

1. Table of Acceptance Criteria and Reported Device Performance:

Acceptance CriteriaReported Device Performance
Color ReproducibilityPixel-wise comparison towards Aperio ImageScopeDX (predicate) across multiple tiles, including zooming and panning operations. Sectra Digital Pathology Module was found to reproduce colors adequately and was non-inferior to ImageScopeDX.
Turnaround Time (Case Load)When selecting a case, it should not take longer than 7 seconds until the image is fully loaded, provided system requirements are fulfilled.
Turnaround Time (Panning)When panning the image (one quarter of the monitor), it should not take longer than 0.5 seconds until the image is fully loaded, provided system requirements are fulfilled.
MeasurementsMeasurement accuracy has been verified using a test image containing objects with known sizes. The device was found to perform accurate measurements.
Human FactorsTask-based usability tests showed the Sectra Digital Pathology Module user interface to be intuitive, safe, and effective for the range of intended users. The device was found to be safe and effective for the intended users, uses, and use environments.

2. Sample Size for Test Set and Data Provenance:

The document does not explicitly state the sample size for any specific test set regarding color reproducibility, turnaround time, or measurements. It mentions a "test image containing objects with known sizes" for measurements, and "multiple tiles" for color reproducibility.

The data provenance is not specified (e.g., country of origin). The testing seems to be internal development and verification testing rather than involving external patient data.

3. Number of Experts for Ground Truth and Qualifications:

The document does not mention the use of experts to establish ground truth for the technical performance tests described (color reproducibility, turnaround time, measurements, human factors). These appear to be objective, quantifiable tests directly comparing the device's output to a known standard or the predicate device's output.

For "Human factors testing," it states "Task-based usability tests showed the Sectra Digital Pathology Module user interface to be intuitive, safe, and effective for the range of intended users." While suggesting involvement of intended users (pathologists likely), the number and specific qualifications of these users are not detailed.

4. Adjudication Method for Test Set:

No adjudication method is mentioned. The tests described are primarily objective comparisons or measurements.

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

No MRMC comparative effectiveness study was done. The document explicitly states: "Substantial equivalence determination is not based upon clinical study results."

6. Standalone (Algorithm Only) Performance Study:

Yes, standalone (algorithm only, meaning the software itself without human interaction for diagnostic purposes) performance was done. The studies listed under "Non-clinical test results" (Color Reproducibility, Turnaround times, Measurements) evaluate the technical performance of the software. The device itself is described as a "software-only device."

7. Type of Ground Truth Used:

  • Color Reproducibility: Ground truth was implicitly the visual output and pixel data of the predicate device (Aperio ImageScopeDX).
  • Turnaround Time: Ground truth was the pre-defined maximum acceptable time limits (7 seconds for case load, 0.5 seconds for panning).
  • Measurements: Ground truth was a "test image containing objects with known sizes."
  • Human Factors: Ground truth was established by assessing usability (intuitiveness, safety, effectiveness) through "task-based usability tests" likely with intended users.

8. Sample Size for the Training Set:

The document does not mention a training set. The Sectra Digital Pathology Module is described as a "software intended for viewing and management of digital images," rather than an AI/ML algorithm that requires a training set.

9. How Ground Truth for Training Set Was Established:

Since no training set is mentioned for an AI/ML algorithm, this question is not applicable based on the provided text. The device is a viewer and management tool, not an AI diagnostic algorithm.

Device Description:

Sectra Digital Pathology Module is a software-only device running under the Microsoft Windows operating system for displaying and manipulating digital pathology images (scanned slides) obtained from the Aperio AT2 DX scanner.

Sectra Digital Pathology Module may only be used in combination with Sectra PACS which consists of Sectra Workstation (K081469) and Sectra Core (identified as a Class I exempt by the FDA in 2000).

The Sectra Pathology Import Server (SPIS) is used for importing digital pathology images (scanned slides) from the scanner. These images are viewed and manipulated by end users in the Pathology Image Window which is displayed on the Sectra Workstation IDS7 (using the Dell MR2416 monitor).

The subject device is typically operated as follows:

    1. The subject device receives quality-controlled images from the scanner and extracts a copy of the images' metadata. The unaltered images are then sent to the external image storage. A copy of the image metadata (e.g. the pixel size) is stored locally in the subject device to increase the operational performance (e.g. response times) of the subject device.
    1. The reading pathologist selects a case (patient) from a worklist external to the subject device whereby the subject device fetches the associated images from the external image storage.
    1. The reading pathologist uses the subject device to view and interpret the images:
    • The pathologist can adjust zoom and pan the image at will. a.
    • b. The pathologist can adjust focus (when different focus depths are available).
    • c. The pathologist can measure distances and areas in the image.
    • d. The pathologist can annotate images.
    • The pathologist can choose to view multiple images side by side in a synchronized e. fashion.
    1. The above steps are repeated as required.

After viewing all images, the pathologist will make a diagnosis will be documented in another system, e.g. a Laboratory Information System (LIS).

multiple tiles. Sectra Digital Pathology Module has been found to reproduce colors adequately with respect to its intended use.
Turnaround timeProvided that the system requirements are fulfilled:- When selecting a case, it should not take longer than 7 seconds until the image is fully loaded.- When panning the image (one quarter of the monitor) it should not take longer than 0.5 seconds until the image is fully loaded.
MeasurementsMeasurement accuracy has been verified using a test image containing objects with known sizes.
Human factors testingSectra Digital Pathology Module has been found to be safe and effective for the intended users, uses, and use environments.

Substantial Equivalence Comparison:

The major difference between the subject and predicate device is that the predicate device includes the Aperio AT2 DX scanner and the Dell MR 2416 Monitor, whereas the subject device is indicated for use with the same scanner and monitor. Therefore, the indications for use are slightly different in that the Aperio AT2 DX System Indication for use includes a section regarding the creation of digital images and the Sectra Digital Pathology Module is only focused on viewing those digital images.

The proposed Sectra Digital Pathology Module when used with the Aperio AT2 DX scanner and Dell MR2416 has similar Indications for Use, Functional, and Technological Characteristics as the ImageScope DX viewer application software of the predicate device and is therefore substantially equivalent to the Aperio predicate device (K190332).

Summary of Studies:

Non-clinical test results:

Conducted per FDA's Guidance on Technical Performance Assessment of Digital Pathology Whole Slide Imaging Devices:

Color Reproducibility Testing demonstrated that the color reproducibility in Sectra Pathology Image Window was non-inferior to the color reproducibility in ImageScopeDX and that the Sectra Digital Pathology Module reproduced colors adequately with respect to its intended use.

Turnaround times for panning and zooming have been determined and found to be adequate for the intended use of the subject device.

The subject device has been found to perform accurate measurements with respect to its intended use.
