Volpara calculates and quantifies a density map and from that determines volumetric breast density as a ratio of fibroglandular tissue and total breast volume estimates. Volpara provides these numerical values along with a BI-RADS breast density 4th or 5th Edition category to aid health care professionals in the assessment of breast tissue composition. Volpara is not an interpretive or diagnostic aid and should be used only as adjunctive information when the final assessment of breast density category is made by an MQSA qualified interpreting physician. | Type of Use (Select one or both, as applicable) | | |-----------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------| | <div> <span> <span style="font-size: 100%;"> </span> </span> Prescription Use (Part 21 CFR 801 Subpart D) </div> | <div> <span> <span style="font-size: 100%;"> </span> </span> Over-The-Counter Use (21 CFR 801 Subpart C) </div> | #### CONTINUE ON A SEPARATE PAGE IF NEEDED.

Volpara calculates and quantifies a density map and from that determines volumetric breast density as a ratio of fibroglandular tissue and total breast volume estimates. Volpara provides these numerical values along with a Bl-RADS breast density 4th or 5th Edition category to aid health care professionals in the assessment of breast tissue composition. Volpara is not an interpretive or diagnostic aid and should be used only as adjunctive information when the final assessment of breast density category is made by an MQSA-qualified interpreting physician. ### Device Description The Volpara 1.5.2 software provides volumetric assessment of digital x-ray images of the breast, including in that definition both digital mammograms and raw tomosynthesis projections. The assessment takes the form of generating and validating density maps where the value at each pixel represents the thickness of fibroglandular tissue between that pixel and the x-ray source. From those density maps various quantitative densitymap based statistics are computed, namely: - volume of fibroglandular tissue in cm3, ● - volume of breast in cm3 ● - the volumetric breast density in %, - a BI-RADS 4th Edition or 5th Edition breast density category ● - average thickness of dense tissue - maximum thickness of dense tissue - maximum volume of dense tissue above any 1cm² square region ● {6}------------------------------------------------ Image /page/6/Picture/0 description: This image contains document information for a report. The report is titled "Volpara Imaging Software 510(k) Summary". The DMS number is mtk1956-007-6, the DMS reference is Eng/Angel, and the revision date is December 26th, 2015. This is page 4 of 5. The device outputs those numbers along with the density maps themselves marked with the location of the various maxima. Volpara operates on a Windows server that meets Volpara data input and output requirements and generally is located outside the patient environment. The device does not contact the patient, nor does it control any life-sustaining devices. ## Performance Data The Volpara software has been verified and validated according to the company's design control process. All of the documents specified in FDA's various software guidance documents have been submitted in the Special 510(k) Notification. A risk analysis compliant with ISO 14971 has been provided and incorporated into the development effort. Software testing included both unit level and integrated system level testing. A report of outstanding anomalies was included in the software information. The modified device was tested and determined to be compliant to the following standards: ISO 14971:2012 Medical devices – Application of risk management to medical devices; 1SO 62304-2006 Software Life Cycle Processes, DICOM 2015. In addition to the verification and validation testing conducted for the specific modification to the software detailed in this Special 510(k), complete verification and validation data testing conducted for the predicate was repeated in order to ensure integration and backwards compatibility. Verification Bench Testing Included: - . Measurement accuracy was assessed by comparing Volpara estimates with known values from breast phantoms. - . Relationship to ground truth was assessed by running Volpara over x-ray images of breasts for which there was 3D breast MRI data available with a comparison of estimates of fibroglandular tissue. - Reproducibility was assessed by running Volpara over substantial datasets where ● we have the women's age and results compared with the expected and known decrease in breast density with age. - Reproducibility was assessed by running Volpara over substantial data sets and the results for left and right breasts and CC and MLO views were compared to confirm that the results were similar for each view and each breast. - . Reproducibility was assessed by running Volpara over substantial data sets where the same woman had been imaged on GE and Hologic systems one year apart and the results were compared to confirm they were similar. {7}------------------------------------------------ Image /page/7/Picture/0 description: The image is a logo for a company called "Mātakina Technology". The logo features a stylized crescent moon shape in light blue, with the company name written in a modern sans-serif font. The word "mātakina" is in a slightly larger font size than "technology", and there is a trademark symbol after the word "technology". The logo has a clean and professional look. - Reproducibility was assessed by running over substantial data sets where the . same woman had been imaged on one of GE, Hologic and Siemens tomosynthesis -compatible units running in both tomosynthesis and mammography modes, and the results were compared to confirm they were similar. - . Relationship to visual assessment was assessed by running Volpara over x-rav images for which a BI-RADS 4th and 5th Edition density category was available from MQSA qualified radiologists followed by a comparison of the two sets of data. ## Clinical Validation Testing Included: - Beta site testing to assess the ability of physicians to successfully integrate the ● software into their existing systems as well as assess usability for target users - Beta site testing to collect minimum, average and maximum Volpara breast . densities and compare these to other existing databases All verification and validation testing was successful in that established acceptance criteria was met for all of the tests conducted. ### General Safety and Effectiveness Concerns: The device labeling contains instructions for use and any necessary cautions and warnings to provide for safe and effective use of this device. Risk management is ensured via a risk analysis, which is used to identify potential hazards. These potential hazards are controlled via software development, verification and validation testing. ## Conclusion: The 510(k) Premarket Notification for Volpara contains adequate information and data to demonstrate substantial equivalence to the predicate device.
