Area of Science:

  • Medical Physics
  • Radiology
  • Quality Assurance

Background:

  • Mammography quality control is essential for accurate breast cancer detection.
  • Established protocols ensure consistent image quality and reliable diagnostic information.

Purpose of the Study:

  • To describe a daily quality control procedure for mammography.
  • To report results from a quality control program implemented in 1994.
  • To highlight the impact of quality control on mammography performance.

Main Methods:

  • Daily quality control by radiological technologists, analyzed by medical physicists.
  • Use of sensitometric strips to determine film characteristic parameters (DIN 6868 Part II).
  • Radiographic testing with a phantom for microcalcification and simulated tumor detection, assessing contrast and background density.

Main Results:

  • Identified variations in mammographic and automatic processing unit performance.
  • Detected malfunctioning automatic exposure control devices.
  • Observed improved image quality after replacing mammography films and processing units.

Conclusions:

  • The implemented quality control program effectively monitors mammography equipment performance.
  • Regular quality control is crucial for maintaining and enhancing diagnostic image quality in mammography.
  • Proactive identification and resolution of equipment issues lead to better patient care.
