Indications for Use
Volpara is a software application intended for use with digital mammography systems. Volpara calculates volumetric breast density as a ratio of fibroglandular tissue and total breast volume estimates. Volpara provides these numerical values for each image to aid radiologists in the assessment of breast tissue composition. Volpara produces adjunctive information. It is not an interpretive or diagnostic aid. Volpara is a software application which runs on Windows or Linux-based computers.
Device Story
Volpara Imaging Software is a fully automated, volumetric analysis tool for digital mammography. It accepts raw ('for processing') DICOM mammography images and associated calibration data as input. Operating on Windows or Linux-based computers, the software uses proprietary algorithms to calculate the volume of fibroglandular tissue, total breast volume, and the resulting volumetric breast density ratio. The output is provided to the radiologist via the console as adjunctive information to assist in assessing breast tissue composition. It does not perform image display or diagnostic interpretation. By providing objective, quantitative density metrics, the device aids clinicians in evaluating breast composition, which may assist in clinical decision-making regarding patient care. It is intended for use in clinical settings by radiologists.
Clinical Evidence
No clinical trials were conducted. Evidence consists of bench testing and beta site usability testing. Bench testing included: measurements against standardized/calibrated breast phantoms; comparison of results against BI-RADS scores; comparison of fibroglandular tissue estimates against 3D breast MRI data; assessment of density trends relative to patient age; comparison of results across different views (CC/MLO) and breasts; and longitudinal consistency checks using images from GE and Hologic systems. Beta site testing assessed software integration and usability, and compared density ranges against existing databases. All acceptance criteria were met.
Technological Characteristics
Software-based image processing application. Inputs: raw DICOM digital mammography images and calibration data. Outputs: quantitative volumetric breast density metrics. Platform: Windows or Linux-based computers. Connectivity: DICOM-compatible. Verification/Validation: ISO 14971 compliant risk analysis, unit and integrated system testing, and testing across GE and Hologic detector datasets.
Indications for Use
Indicated for use by radiologists to aid in the assessment of breast tissue composition using digital mammography images. Provides quantitative volumetric breast density measurements (fibroglandular tissue volume, total breast volume, and density ratio). Not for diagnostic or interpretive use.
Regulatory Classification
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.
