AI/ML Overview

This 510(k) submission for the Siemens syngo MultiModality Workplace (syngo MMWP) does not include a study proving device performance against acceptance criteria in the typical sense of a clinical or performance study with metrics like sensitivity, specificity, or reader agreement.

Instead, this submission is centered on demonstrating substantial equivalence to a previously cleared predicate device (syngo MultiModality Workplac (K052775) and MAGNETOM Systems with Expert-i option (K052423)). For general PACS (Picture Archiving and Communications System) software like the syngo MMWP, the "acceptance criteria" are primarily related to conforming to established standards, ensuring proper image display and manipulation, and maintaining data integrity, rather than diagnostic performance metrics.

Therefore, many of the requested points below cannot be directly extracted from the provided text, as the focus is on safety, effectiveness, and equivalence to existing technology.

Here's an breakdown based on the information available and the nature of this type of device submission:


1. Table of Acceptance Criteria and Reported Device Performance

As a general PACS workstation for viewing, manipulating, communicating, and storing medical images, the “acceptance criteria” are primarily conformance to established standards and ensuring functional equivalence to the predicate. Specific quantitative diagnostic performance metrics are not typically required for a device of this classification.

Acceptance Criteria (Implied)Reported Device Performance (Implied from Substantial Equivalence Claim)
Functional equivalence to predicate devices (K052775, K052423)The syngo MultiModality Workplace has the "same intended use and similar technical characteristics" as the predicate devices and "performs as well."
Compliance with DICOM standardsThe workplace "supports DICOM formatted images and information."
Risk management and safety"Risk management is ensured via a risk analysis," with hazards controlled by software development, verification, and validation testing. Adheres to "recognized and established industry practice and standards" to minimize hazards.
Proper display, manipulation, communication, and storage of medical imagesThe device offers a "comprehensive solution to view, optimize, process diagnostic information and aid the doctors in the evaluation of digital radiological examinations and patient information." Supports "realtime viewing, manipulation, communication, and storage of medical images and data on exchange media."
Excludes mammography for diagnosisExplicitly states: "The syngo MultiModality Workplace does not support the display of mammography images for diagnosis."

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

  • Sample Size: Not specified. Performance testing for a PACS workstation typically involves extensive internal verification and validation with a wide variety of anonymized clinical images rather than a single "test set" with a defined sample size for a specific clinical endpoint.
  • Data Provenance: Not specified. Given it's a Siemens product developed in Germany, it's highly likely that testing data would include a mix of internal, international, and potentially U.S. clinical data, if specific clinical data were used, but the document does not elaborate. This type of submission relies more on functional testing and adherence to standards than a specific clinical dataset.

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

Not applicable. This is not a diagnostic AI/CAD device requiring expert-established ground truth for clinical performance evaluation. The "ground truth" for a PACS workstation is determined by its ability to accurately display, process, and transmit medical images as per DICOM standards and clinical requirements, which relies on engineering and software validation, not expert medical adjudication of diagnoses.


4. Adjudication method (e.g., 2+1, 3+1, none) for the test set

Not applicable. See point 3.


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. This is not an AI-assisted diagnostic device. It is a general PACS workstation. Therefore, an MRMC study and AI assistance effect size are not relevant to this submission.


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

No specific "standalone algorithm performance" study is described because the device is an interactive workstation designed for human users. The performance is assessed in terms of its functionality in supporting human users, not as an autonomous diagnostic algorithm.


7. The type of ground truth used

Not applicable in the sense of expert consensus, pathology, or outcomes data for a diagnostic performance evaluation. The "ground truth" for this device relates to the fidelity and accuracy of image display, processing, and storage according to technical specifications and DICOM standards. This is verified through technical validation, not clinical ground truth.


8. The sample size for the training set

Not applicable. This is not an AI/ML device that requires a "training set" in the context of machine learning model development. This is a conventional software application (PACS).


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

Not applicable. See point 8.
