Image effect is show in the figure below:
6.5.2.5 Lateral Geometric Positioning Accuracy
Note:
 For linear array probes, the lateral interval can be read section by section.
 For convex array probes, all lateral targets mus be displayed at a time.
 The measurement scale should be placed above or under the center of the target to be
measured.
Test procedure:
1. Place the probe gently on the acoustic window of phantom which is covered by water or medical
ultrasonic couplant.
2. Adjust display depth, to make horizontal groups display in the image.
3. Adjust focus to be in horizontal groups (no explicit standard).
4. Adjust gain, TGC and etc. to make horizontal groups display clearly.
5. Use caliper to measure horizontal target distance by step of 20 mm.
6. Select all measurement values deviating largely from 20 mm, and calculate the error by the
following formula.
