Quality assurance
A good Quality Assurance Evaluation program consists of
periodic systematic actions that provide the user with adequate
confidence that their diagnostic ultrasound system will produce
consistently high-quality images and quantitative information.
Therefore, it is in the best interests of every ultrasound user to
routinely monitor equipment performance.
Typical Tests to Perform
Quality assurance measurements provide results relating to
system performance. Typically. these are:
• Axial Measurement Accuracy
• Lateral Measurement Accuracy
• Axial and Lateral Resolution
• Penetration
•
Functional and Contrast Resolution
• Gray Scale Photography.
With these tests, a performance baseline can be set at
installation with the phantom in your department. Future test
results can be compared to the baseline in order to maintain a
record of system performance trends.
