Quality assurance measurements provide results relating to
system performance. Typically these are:
Axial Measurement Accuracy
Lateral Measurement Accuracy
Axial and Lateral Resolution
Penetration
Functional & 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.
The phantom shown is shown as a representative example of a
phantom. You can select from any number of phantoms
available on the market.
Quality assurance tests are used to determine whether a
scanner is providing the same level of performance from day to
day.
The frequency of testing varies with the amount of system usage
and modes to be tested. It is recommended that the operator
perform quality assurance tests at least every three months or
every 400 patient studies. Tests should also be performed when
a question about system performance exists.
A mobile system may require more frequent tests.
Image quality should also be tested immediately after the
following events:
