BMUS guidelines for the regular quality assurance testing of ultrasound scanners by sonographers

Abstract

Quality Assurance of ultrasound systems is necessary to ensure the reliability of results and to check for deterioration in performance; a number of bodies have produced guidelines. Testing has traditionally been the responsibility of Medical Physics Departments but the important role of sonographers has been recognised and recent publications have included tests to be performed by ultrasound users. Since there are differences in approach between these publications the BMUS QA Working Party was established to provide a consistent set of guidelines specifically for sonographers. Three levels of testing are recommended, to include infection control and inspections for scanner and probe damage, basic display checks and further tests to assess drop-out, sensitivity and noise. These tests should form part of a programme that includes more comprehensive testing at longer intervals, perhaps by a Medical Physics Department.
