INFINITT DPS is a software device intended for viewing and management of whole slide digital images derived from scanned surgical pathology slides prepared from formalin-fixed, paraffin-embedded (FFPE) tissue. It serves as an aid for pathologists to review and interpret these digital images for the purpose of pathology primary diagnosis.
INFINITT DPS is intended for use with Hamamatsu NanoZoomer S360MD scanner and Barco MDPC-8127 display.
It is the responsibility of the pathologist to implement appropriate procedures and safeguards that assure the integrity and accuracy of image interpretation when utilizing the INFINITT DPS. The system is not intended for use with frozen sections, cytology, or non-FFPE hematopathology specimens.
INFINITT DPS software provides a more efficient and convenient alternative to reviewing slides with physical microscopes. The primary users of INFINITT DPS are pathologists in histopathology, as well as technologists who handle specimens. Users can access whole slide images directly through a web browser, with no need to install additional software on the client PC.
INFINITT DPS, version 1.1, is a web-based software device that enables qualified pathologists to review digital pathology images (WSIs) of formalin-fixed, paraffin-embedded (FFPE) tissue specimens for pathology primary diagnosis. The device operates through a supported web browser without installing any application locally.
The Operation and Workflow of INFINITT DPS are described below:
- Data Input
- The device accepts WSI files in the NDPI file format generated by a Hamamatsu NanoZoomer S360MD Slide Scanner. The WSI files are internally converted into the Digital Imaging and Communications in Medicine (DICOM) file format using the built-in INFINITT DPS Acquisition module.
- Data Management and Storage
- The converted images are stored on the INFINITT DPS server. The user is highly recommended to back up the original NDPI files. The device can be integrated with an external LIS (Laboratory Information System)/EMR (Electronic Medical Record) system to automate case registration and retrieval.
- Image Access and Navigation
- Users can log in to the device using the INFINITT DPS WebViewer running on a supported web browser (i.e., Chrome, Edge, or Firefox). The stored WSIs can be searched, selected, and opened directly within the INFINITT DPS WebViewer.

Page 10
across three web browsers (Chrome, Edge, Firefox). Each slide included 3 ROIs captured at 3 magnification levels. All 95th percentile ΔE₀₀ values averaged 0.00 (maximum 95th percentile ΔE₀₀ values were 0), indicating no significant difference between the subject and predicate viewers.
• Measurement Accuracy Test: The subject device was tested for length and area measurement accuracy using various annotation tools (e.g., ruler, region) on multiple WSIs at 20x and 40x magnification, with 2 different orientations. Measurements from INFINITT DPS were compared to those from the predicate device. All results met the predefined acceptance criteria of ±2% or ±5 μm for length and ±5% for area, confirming measurement accuracy.
• Turnaround Time (TAT) Test: This test assessed image load times and responsiveness during interactions such as panning and zooming. Using browser developer tools, timestamps were recorded and analyzed. WSIs loaded within an average of 2.8 seconds, and all interactions responded within an average of 0.48 seconds, meeting the criteria of ≤5 seconds for load time and ≤1 second for interaction latency.
In summary, all testing phases for the INFINITT DPS — including software V&V, Human Factors Engineering, Cybersecurity assessments, and Non-Clinical Bench Performance Testing (Pixel-wise Comparison, Measurement Accuracy, and Turnaround Time) — were completed successfully. INFINITT DPS meets its performance, usability, and security requirements, supporting its safe and effective use in a clinical setting.

(I) Image review manipulation software;
(J) Computer environment; and
(K) Display system.
(iii) Detailed bench testing and results at the system level, including for the following, as appropriate:
(A) Color reproducibility;
(B) Spatial resolution;
(C) Focusing test;
(D) Whole slide tissue coverage;
(E) Stitching error; and
(F) Turnaround time.
(iv) Detailed information demonstrating the performance characteristics of the device, including, as appropriate:
(A) Precision to evaluate intra-system and inter-system precision using a comprehensive set of clinical specimens with defined, clinically relevant histologic features from various organ systems and diseases. Multiple whole slide imaging systems, multiple sites, and multiple readers must be included.
(B) Reproducibility data to evaluate inter-site variability using a comprehensive set of clinical specimens with defined, clinically relevant histologic features from various organ systems and diseases. Multiple whole slide imaging systems, multiple sites, and multiple readers must be included.
(C) Data from a clinical study to demonstrate that viewing, reviewing, and diagnosing digital images of surgical pathology slides prepared from tissue slides using the whole slide imaging system is non-inferior to using an optical microscope. The study should evaluate the difference in major discordance rates between manual digital (MD) and manual optical (MO) modalities when compared to the reference (
e.g., main sign-out diagnosis).(D) A detailed human factor engineering process must be used to evaluate the whole slide imaging system user interface(s).
(2) Labeling compliant with 21 CFR 809.10(b) must include the following:
(i) The intended use statement must include the information described in paragraph (b)(1)(i) of this section, as applicable, and a statement that reads, “It is the responsibility of a qualified pathologist to employ appropriate procedures and safeguards to assure the validity of the interpretation of images obtained using this device.”
(ii) A description of the technical studies and the summary of results, including those that relate to paragraphs (b)(1)(ii) and (iii) of this section, as appropriate.
(iii) A description of the performance studies and the summary of results, including those that relate to paragraph (b)(1)(iv) of this section, as appropriate.
(iv) A limiting statement that specifies that pathologists should exercise professional judgment in each clinical situation and examine the glass slides by conventional microscopy if there is doubt about the ability to accurately render an interpretation using this device alone.
