Area of Science:

  • Radiology
  • Medical Imaging
  • Biomedical Engineering

Background:

  • Breast compression in mammography enhances image quality and lowers radiation dose.
  • Current compression levels are not standardized, varying by patient, equipment, and usage conditions.

Purpose of the Study:

  • To develop and assess a system for accurately measuring breast compression pressure.
  • To enable standardization of breast compression in mammography.

Main Methods:

  • A pressure measuring system was designed using a fluid-filled neonatal cuff and a pressure transducer.
  • The system was calibrated and tested both in vitro and in vivo with patients.

Main Results:

  • The developed system accurately quantifies breast pressure during mammography.

Related Experiment Videos

  • It provides a practical and simple method to correlate breast pressure with mammography unit readings.

    • Conclusions:

    • The pressure measuring system is feasible for clinical use.
    • This tool can help standardize breast compression, improving mammography consistency and patient safety.
