PracticeBuilder 1-2-3 is a PACS and teleradiology system used to receive DICOM images, scheduling information and textual reports, organize and store them in an internal format, and to make that information available across a network via web and customized user interfaces.

PracticeBuilder 1-2-3 is for use in hospitals, imaging centers, radiologist reading practices and any user who requires and is granted access to patient image, demographic and report information.

PracticeBuilder 1-2-3 is a PACS system, comprised of acquisition components (GatewayServer and SendServer), a central system manager component (SmartServer), a diagnostic workstation component (Workstation and Viewer), and an archiving component (ArchiveServer). The data flow is such that patient and procedure information is optionally delivered to the central system manager, followed by the acquisition of the image objects directly from the image sources or by one of the acquisition components. After receiving the procedure information or after receiving image objects, the central system manager searches for and retrieves relevant prior procedure data from the archive component. When the central system manager registers the acquired image objects and the retrieved prior procedure data, a user can access the information by selecting the item from the operator worklist. The image data is transmitted to and rendered on the user's workstation using the diagnostic workstation components. After using the workstation to view the images, the user optionally dictates a report into the system, after which, a user can play back the dictation and transcribe it to text. Once PracticeBuilder 1-2-3's central system manager registers a report, the report is available for access by the referring physician, or it can be exported into an information system. At some configured point in time, the image data and the report information is delivered to the archiving component for backup and long-term storage.

PracticeBuilder 1-2-3 is also a teleradiology system used to receive DICOM images, scheduling information and textual reports, organize and store them in an internal format, and to make that information available across a network via web and customized user interfaces.

The provided text is a 510(k) summary for the PracticeBuilder 1-2-3 PACS system. It focuses on demonstrating substantial equivalence to predicate devices and does not contain information about specific acceptance criteria, performance studies with quantitative metrics, or details about ground truth establishment, sample sizes for training/test sets, or expert qualifications for a standalone AI algorithm or MRMC study.

Here's a breakdown of what is and is not available in the provided document, based on your request:

1. Table of Acceptance Criteria and Reported Device Performance:

• Not Available. The document does not specify quantitative acceptance criteria (e.g., sensitivity, specificity, AUC, image quality metrics) or report device performance against such criteria. The "Validation and Effectiveness" section only states that "Extensive testing of the software package has been performed by programmers, by non-programmers, quality control staff, and by potential customers." This is a general statement about testing practices, not a detailed performance study.

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

• Not Available. The document does not mention any specific test set, its sample size, or the provenance of any data used for testing.

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

• Not Available. Ground truth establishment, the number of experts involved, or their qualifications are not mentioned.

4. Adjudication Method:

• Not Available. Since no ground truth establishment is described, no adjudication method is mentioned.

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

• Not Available. There is no mention of an MRMC study or any comparison of human reader performance with or without AI assistance. This device is a PACS system, not an AI diagnostic aid.

6. Standalone (Algorithm Only) Performance Study:

• Not Available. The device is a PACS system designed for image management and display, not a standalone AI algorithm. Therefore, no standalone performance study in the context of an AI algorithm is described.

7. Type of Ground Truth Used:

• Not Available. Given the nature of the device (PACS), the concept of "ground truth" for a diagnostic algorithm is not applicable here in the way it would be for an AI diagnostic device. The document focuses on the functional equivalence of the PACS system.

8. Sample Size for the Training Set:

• Not Available. This information is not relevant for a PACS system that is not an AI algorithm requiring a training set.

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

• Not Available. Same reasoning as point 8.

In summary:

This 510(k) submission for the PracticeBuilder 1-2-3 PACS system relies on establishing substantial equivalence to existing legally marketed predicate devices (Stentor iSite, Agfa IMPAX, Ultravisual Vortex). The "effectiveness" is primarily demonstrated through the functional equivalence of its components (acquisition, central manager, workstation, archive, teleradiology capabilities) to these predicates. The review focuses on software development practices and general safety and effectiveness concerns rather than specific quantitative performance metrics for a diagnostic algorithm.
