Measuring Image Quality and User QA
Overview
This lecture covers how to assess and maintain ultrasound image quality. It includes the use of ultrasound phantoms to evaluate system performance, and practical quality assurance steps to ensure equipment is functioning safely and effectively in clinical practice.
Learning Outcomes
By the end of these lectures, you should be able to:
-
Describe the role of user-led quality assurance (QA) procedures in monitoring ultrasound equipment performance.
-
Identify common signs of ultrasound equipment damage using visual inspection, in air reverberation, and paper clip tests.
-
Demonstrate an understanding of methods used to measure ultrasound system performance, including axial and lateral resolution, penetration, and calliper accuracy.
-
Discuss how scanner settings and transducer characteristics influence image quality.
