5-16 Function and Performance Checking Method
5. Record the distance by 20mm each segment on the transverse targets line by using the
measurement caliper
6. Select the value with the greatest error (to 20mm), calculate the accuracy by using the formula
below
When using a linear probe, record the transverse distance by segment.
When using a convex probe, all transverse targets should be displayed
integrally in an image.
The measure caliper should be posited at the upper side or lower side of
the target center.
As shown in figure below.
