The summary describes image processing and calculation of metrics based on thresholds, but does not mention AI or ML techniques.
No
The device is described as a software application that calculates and quantifies breast density from x-ray data to aid healthcare professionals in assessment. It is explicitly stated that it is "not an interpretive or diagnostic aid" and merely provides "adjunctive information." It does not provide any treatment or therapy.
No
The "Intended Use / Indications for Use" section explicitly states, "Volpara is not an interpretive or diagnostic aid." It is intended to provide numerical values and a BI-RADS category to aid healthcare professionals in assessing breast tissue composition, acting as adjunctive information.
Yes
The device is described as "Volpara Imaging Software" and its function is solely based on processing raw data from digital breast x-ray systems to calculate and quantify breast density. It operates on a Windows server and does not include any hardware components or direct patient contact.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze specimens from the human body. The description clearly states that Volpara works with "raw data from digital breast x-ray systems" and "digital x-ray images of the breast." It processes imaging data, not biological samples like blood, urine, or tissue.
- The intended use is for image analysis and quantification. The software calculates and quantifies breast density from imaging data to aid healthcare professionals in assessing breast tissue composition. This is a function related to medical imaging analysis, not in vitro testing.
Therefore, Volpara falls under the category of medical imaging software, not an IVD.
N/A
Intended Use / Indications for Use
Volpara is a software application intended for use with the raw data from digital breast x-ray systems, including tomosynthesis. 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.

Device Description
The Volpara Imaging Software ("Volpara") 1.5.6 software provides volumetric assessment of digital x-ray images of the breast, including in that definition both raw digital mammograms and raw tomosynthesis projections (the central projections of which are just raw digital mammograms).
The assessment takes the form of generating and validating density maps wherein the value at each pixel represents the thickness of fibroglandular tissue between that pixel and the x-ray source.
From the density maps various quantitative density-map based statistics are computed as follows:
- . volume of fibroglandular tissue in cm3
- volume of breast in cm3. ●
- the volumetric breast density (the percentage of fibroglandular tissue in breast) ●
- average thickness of dense tissue in cm ●
- maximum thickness of dense tissue in cm ●
- maximum volume of dense tissue above any 1cm² square region (or "focal ● density")
- image quality assessment metrics ●
From the volumetric breast density, a BI-RADS 4th Edition and 5th Edition breast density category can be attained by applying thresholds set by the software, with an increase in density category if a focal density appears to be present.
The device outputs those metrics 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.

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)
