Intended Use

PatientGallery is a Windows-based image management system indicated for use primarily by dentists to acquire, archive, display, edit, print, email, and import/export digital images.

Device Description

PatientGallery Imaging Software is a Windows-based image management database, or system used primarily by Dentists for the indications of acquiring, archiving, displaying, editing, printing, emailing, and importing or exporting digital images.

The database is organized like a file cabinet by patient folder accommodates grayscale and color images which may also include textual and graphic notes and annotations. Images may be assembled into layouts which can be customized as required. Optional modules provide editing and viewing functions.

Image acquisition from x-ray sensors, intra-oral video cameras, digital cameras and flatbed scanners can be distributed among several workstations. The software provides direct interfaces to many industry standard devices through OEM toolkits. PatientGallery Imaging Software uses standard Windows peer-to-peer networking. By default, images are stored in the native format provided by the hardware manufacturers. PatientGallery Imaging Software may be invoked by other practice management applications so that specific patient information is accessed.

AI/ML Overview

Here's the analysis of the provided text regarding the acceptance criteria and study for the PatientGallery Imaging Software:

This submission (K070954) for the PatientGallery Imaging Software does not contain the detailed information requested regarding specific acceptance criteria for diagnostic performance or a study demonstrating such performance.

Instead, the submission focuses on the functionality and safety of the software as an image management system, demonstrating substantial equivalence to a predicate device based on its intended use and general software verification and validation.

Therefore, many of the requested fields cannot be directly populated from the provided document. I will fill in what can be inferred or explicitly stated, and note when information is missing.

2. Sample size used for the test set and the data provenance

  • Sample Size for Test Set: Not specified in terms of clinical images or cases. The "Test Cases" mentioned refer to software verification and validation testing, not a clinical performance study with patient data.
  • Data Provenance: Not applicable, as no clinical test set using patient data is described. The "Test Cases" would typically involve synthetic or controlled data to verify software functions.

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

  • Not applicable. The "ground truth" for the software's functional performance would be its adherence to predefined software requirements, not clinical diagnoses established by medical experts.

4. Adjudication method for the test set

  • Not applicable. No clinical test set requiring adjudication is described. Software V&V testing typically involves comparing actual software output to expected output based on specifications.

5. 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. An MRMC comparative effectiveness study was not done. The device is an image management system, not an AI diagnostic aid.

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

  • The "V&V testing" refers to standalone software testing to ensure it meets its functional requirements. This is not a "standalone (algorithm only)" performance in the context of diagnostic accuracy, but rather functional software performance.

7. The type of ground truth used

  • The "ground truth" for the V&V testing was the Software Requirement Specifications (SRS). The software was tested to ensure it performed according to these written specifications.

8. The sample size for the training set

  • Not applicable. This device is an image management system, not a machine learning or AI algorithm that requires a training set of data.

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

  • Not applicable. No training set is used for this type of software.

§ 892.2050 Medical image management and processing system.

(a)
Identification. A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.(b)
