Mammo Tomosynthesis (MDMG-5221)
The Barco Mammo Tomosynthesis (MDMG-5221) device is intended to be used in displaying and viewing digital images, including standard and multi-frame digital mammography, for review, and diagnosis by trained medical practitioners.
It is specially designed for breast tomosynthesis applications.
MDMG-5221, system name Barco Mammo Tomosynthesis, is an update of the 5MP display, specifically addressing the requirements of the emerging modality of Digital Breast Tomosynthesis (DBT) and QA software.
The display controller board is installed in a PACS workstation computer, connected to the display. The QA software helps to make and keep the displays DICOM compliant.
The display uses LED backlight technology.
The provided text describes a 510(k) Summary for the Barco Mammo Tomosynthesis (MDMG-5221) device. This submission primarily focuses on demonstrating substantial equivalence to a predicate device, rather than proving a new device meets specific acceptance criteria through extensive clinical studies.
Here's a breakdown of the information requested, based on the provided document:
1. Table of Acceptance Criteria and Reported Device Performance
The document does not specify formal "acceptance criteria" in the sense of performance thresholds for a clinical study (e.g., a specific sensitivity or specificity target). Instead, it compares the technical specifications and performance of the new device to its predicate. The "acceptance criteria" can be inferred as demonstrating comparable or superior performance in key technical aspects and safety as the predicate device.

| (Specific for LED backlight and firmware update) | DICOM calibration and Luminance Uniformity tests passed. Firmware tests passed. Electrical Safety (IEC 60601-1) and EMC (IEC 60601-1-2) tests passed. |
2. Sample Size Used for the Test Set and Data Provenance
The document explicitly states: "Animal or clinical testing have not been performed." Therefore, there is no test set of patient data, sample size, or data provenance from a clinical study to report. The "testing" referred to in the document is bench testing of the display device itself.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
Not applicable, as no clinical test set with medical images requiring expert ground truth was used in this submission.
4. Adjudication Method for the Test Set
Not applicable, as no clinical test set was used.
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
Not applicable. This device is a display monitor, not an AI-powered diagnostic tool. The submission does not involve an MRMC study or AI assistance.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was Done
Not applicable. This device is a display monitor, not an algorithm.
7. The Type of Ground Truth Used
Not applicable. No clinical ground truth was established as no clinical studies were performed. The "ground truth" for the technical performance tests would be the established engineering specifications and measurement standards.
8. The Sample Size for the Training Set
Not applicable. As this is a display monitor submission demonstrating substantial equivalence via technical bench testing, there is no "training set" in the context of an algorithm or AI.
9. How the Ground Truth for the Training Set Was Established
Not applicable. There is no training set mentioned or implied in this submission for this device.
