midline of the image.

5-10 Function and Performance Checking Method

2. Adjust the focus point focuses at the position where the transverse resolution testing targets
are displayed.

3. Adjust parameters like gain, dynamic range, TGC, making the background tissue unseen, just
displaying the target image clearly.

4. In condition that the transverse resolution testing targets are horizontally displayed, record the
minimal distance of two targets that can be clearly recognized.

5. Repeat the operation above for the transverse resolution testing targets at other depths.

As shown in figure below.

 Axial resolution
Test Step:

1. Cover the scan surface of the phantom with water or couple gel, gently contact the probe with
the scan surface, making the longitudinal resolution testing targets to be displayed around the
midline of the image.

2. Adjust the focus point focuses at the position where the longitudinal resolution testing targets
are displayed.

3. Adjust parameters like gain, dynamic range, TGC, making the background tissue unseen, just
displaying the target image clearly.

4. Record the minimal distance of two longitudinal resolution testing targets that can be clearly
recognized.

5. Repeat the operation above for the longitudinal resolution testing targets at other depths.

Function and Performance Checking Method 5-11

NOTE:

1.

When using the convex probe, keep the transverse resolution testing targets to
be displayed near the midline.

2.

When using a linear probe with steer function, do not turn on the steer function
when perform the transverse resolution test.

3.

Zoom in the region where the targets located if necessary.

4.

The diameter of the target point at a certain depth is equal to the transverse
resolution at the depth.

NOTE:

1.

Increasing the gain will also increase the noise, and echo may be covered.

2.

When using a linear probe, please completely contact the probe with the scan
surface, no side clearance is allowed.

3.

When using a convex or phased-array probe, make the axis targets to be
displayed at the middle of the scanning image.

4.

When system is not frozen, the fast field target information may be similar to that
of the noise, do not use this target.

5.5.2.2 Maximum Depth

Test Step:

1. Cover the scan surface of the phantom with water or couple gel, gently contact the probe with
the scan surface

2. Set the system display depth according to the expected maximum available depth of the probe
in use.

3. Adjust the focus point to the deepest, and AP at the maximum value.

4. Set gain, contrast, TGC at a greater value, but no halation nor defocus is allowed.

5. Record the depth of the furthest target (the target can be seen clearly).

As shown in figure below.
