VolparaDoseRT is an add-on module to VolparaDensity, which uses volumetric quantitative data for a patient-specific assessment of the mean glandular dose (MGD) per image. It also supplies the applied pressure during the acquisition of those images. These results are displayed on the secondary capture image and the patient-specific dose and density results can also be integrated into patient letters for reporting (from the SC Image or from a Mammography CAD SR).

Secondary Capture with dose and pressure

This is an example of a VolparaDoseRT secondary capture where the mean glandular dose was 2.3 mGy per image (shown in the lower left corner).


Mean Glandular Dose

VolparaDoseBreast glandular tissue is sensitive to radiation, and absorbs more radiation than fatty tissue. Mammography unit manufacturers estimate density using calculations based on assumptions of a homogeneous mixture of fat and fibroglandular tissue in standard, non-personalized proportions. This results in dose being routinely under- or over-estimated. VolparaDoseRT uses patient-specific volumetric density results to calculate the dose and standardizes the way MGD is assessed across the different manufacturers’ mammography units, by using the same globally-accepted and validated algorithm.

Average Applied Pressure

VolparaAppliedPressureEither excessive or insufficient pressure to the breast during screening will negatively impact image quality. VolparaDoseRT displays the applied pressure which is based on the compression force and contact area. By measuring the applied pressure, practices can monitor for improper compression from inexperienced technologists or mammography units with different automated breast compression settings. Corrective action can be taken quickly in order to to operate in an optimal range that improves patient experience, attendance rates, and image quality.


Insufficient pressure

  • Patient movement can blur image
  • Dose exposure is increased
  • Separation of overlapping tissue is poor


Excessive pressure

  • Increased discomfort or pain for woman
  • Severe paddle tilt reduces image quality
