• Line target system
The TM material is embedded with 11 line targets, which are distributed as shown in the figure:
A1-A4:
Axial resolution target group. The upmost lines in each target locate at the depth of 10, 30, 50,
70mm, the center longitudinal distances of each group (from the top down) are 3, 2, 1, 0.5mm,
and the horizontal distance is 1mm.
B1-B4:
Lateral resolution target group. They are located at a depth of 10mm, 30mm, 50mm, 70mm,
with a center horizontal distance of 4mm, 3mm, 2mm, and 1mm in each group.
C:
Dead zone target group. The center horizontal distance of the four adjacent lines on the right is
10mm, and the distances to the acoustic window are 8mm, 7mm, 6mm, and 5mm. The center
horizontal distance of the three adjacent lines on the left is 15mm, distances to the acoustic
window are 4mm, 3mm, and 2mm.
D:
Vertical target group. It contains 12 target lines, and the center distance between two adjacent
lines is 10mm.
E:
Horizontal target group. It is located at the depth of 40mm, and the center distance between
two adjacent lines is 10mm.
