Intended Use
FullFocus™ is a software only device 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, interpret, and manage digital images of pathology slides for primary diagnosis. FullFocus is not intended for use with frozen sections, cytology, or non-FFPE hematopathology specimens. It is the responsibility of a qualified pathologist to employ appropriate procedures and safeguards of the images obtained and, where necessary, use conventional light microscopy review when making a diagnostic decision. FullFocus is intended for use with Philips Ultra Fast Scanner and monitor displays validated with verified test methods to meet required performance characteristics.
Device Description

FullFocus reproduces the whole slide images and is an aid to the pathologist to review. interpret and manage digital images of pathology slides for primary diagnosis.
More Information

Not Found

No
The document describes software for viewing and managing digital pathology images, focusing on basic image manipulation and display. There is no mention of AI, ML, or any advanced analytical capabilities that would typically involve these technologies. The performance studies focus on image reproduction, speed, measurements, and usability, not on algorithmic performance related to diagnosis or analysis.

No.
The device is described as a software-only device for viewing and managing digital images of pathology slides, intended as an aid for pathologists in primary diagnosis. It does not directly treat or prevent a disease or condition.

Yes

The "Intended Use / Indications for Use" section explicitly states that the device is "an aid to the pathologist to review, interpret, and manage digital images of pathology slides for primary diagnosis." Primary diagnosis is a key step in diagnostic medicine.

Yes

The device description explicitly states "FullFocus is a web-based software-only device". While it relies on images from a specific scanner and validated monitors, the device itself is presented as purely software for viewing and manipulating those images.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use explicitly states that FullFocus is "an aid to the pathologist to review, interpret, and manage digital images of pathology slides for primary diagnosis." This directly relates to the diagnostic process performed on biological specimens (tissue slides).
  • Specimen Type: The device is intended for use with "digital images of scanned surgical pathology slides prepared from formalin-fixed paraffin embedded (FFPE) tissue." This is a classic type of in vitro diagnostic specimen.
  • Role in Diagnosis: While it's a software-only device and an "aid" to the pathologist, its function is to facilitate the review and interpretation of images that are used to make a primary diagnosis. This places it within the scope of IVD devices, which are used to examine specimens from the human body to provide information for diagnostic purposes.
  • Predicate Device: The predicate device listed, Philips IntelliSite Pathology Solution (PIPS), is also an IVD device. This further supports the classification of FullFocus as an IVD.

The fact that it's software-only and processes digital images doesn't exclude it from being an IVD. The key is its intended use in the diagnostic process involving in vitro specimens.

Device Description

FullFocus is a web-based software-only device for viewing and manipulating digital pathology images of glass slides obtained from the Philips IntelliSite Pathology Solution (PIPS) Ultra Fast Scanner (UFS) on the monitor displays that are validated with verified test methods to meet required performance characteristics. FullFocus reproduces the whole slide images and is an aid to the pathologist to review. interpret and manage digital images of pathology slides for primary diagnosis.

The subject device is typically operated as follows:

    1. The image acquisition is performed using the predicate device, PIPS UFS. The operator performs quality control of the digital slides per the instructions of PIPS and lab specifications to determine if re-scans are necessary.
    1. Once slide image is acquired using PIPS UFS, according to its Instructions for Use, and becomes available in scanner database file systems, a separate medical image communications software (not part of the device) will automatically initiate uploading the slide image and corresponding metadata to persistent cloud storage. Integrity checks are being performed at upload time when data is copied to storage.
    1. The reading pathologist uses the subject device to select a case (patient), view the images and is able to perform the following actions, as needed:
    • a. Zoom and pan the image
    • b. Measure distances and areas in the image
    • c. Annotate images

After viewing all images belonging to a particular case (patient), the pathologist will make a diagnosis.

FullFocus is compatible with:

  • Monitor displays:
    • Barco PP27QHD
    • Philips PS27QHDCR
  • FDA-cleared scanners:
    • Philips Ultra Fast Scanner
  • Browsers:
    • Google Chrome
    • Microsoft Edge
    • Firefox

Additional monitor displays will be validated with verified test methods to meet required performance characteristics.

Performance dataDescription
Pixel-wise comparisonBased on pixel-wise comparison to PIPS, including zooming and
panning operations across multiple tiles, FullFocus has been found
to visually adequately reproduce digital pathology images to
human readers with respect to its intended use.
Turnaround timeThe system requirements have been fulfilled:
· When selecting a case, it should not take longer than 10 seconds
until the image is fully loaded.
· When panning the image (one quarter of the monitor) it shall
not take longer than 7 seconds until the image is fully loaded.
MeasurementsMeasurement accuracy has been verified using a test image
containing objects with known sizes.
Human factors testingFullFocus 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 Ultra Fast Scanner (UFS) and Philips PS27QHDCR monitor display, whereas the subject device is only the review software and indicated for use with the same scanner and monitor. The indications for use are slightly different since the PIPS Indication for Use includes the creation of digital images and FullFocus Indication for use solely describes viewing and managing those digital images.

When FullFocus is used with the PIPS UFS scanner and Philips PS27QHDCR monitor, the software has similar Indications for Use. Functional, and Technological Characteristics to the predicate Image Management System (IMS) application software and is therefore substantially equivalent to the predicate device (DEN160056).

Summary of Studies

Non-clinical test results

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

Pixel-wise comparison study was conducted to compare color images reproduced by FullFocus and PIPS IMS. It was determined that color images reproduced by FullFocus were visually adequate 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.

7

Conducted per FDA's Guidance on Applying Human Factors and Usability Engineering to Medical Devices:

Task-based usability tests verified the FullFocus user interface to be intuitive, safe, and effective for the range of intended users.

Conclusion:

When FullFocus is used with the PIPS UFS scanner and PS27QHDCR monitor display, it has similar Indications for Use, Functional, and Technological Characteristics as the predicate IMS viewer application software. The results of non-clinical testing demonstrate the device is substantially equivalent to the PIPS (DEN160056).
