A1-A5: Axial-lateral resolution target string group
B: Dead zone target group
C: Vertical target group
D: Horizontal target group
E: Hyperechoic (tumor-like) target
F: Pseudocyst (10 mm in diameter) and stones
G: Pseudocyst (6 mm in diameter)
• Line target system
The TM material is embedded with eight groups of nylon line targets, which are distributed as
shown in the figure. Where,
A1-A5
Axial and lateral resolution target group. The distances between the lateral branches of the
group and the acoustic window are 30mm, 50mm, 70mm, 120mm and 160mm respectively.
The horizontal distances between two adjacent target lines in groups A1 and A2 are 1mm,
5mm, 4mm, 3mm, and 2mm, and those in groups A3-A5 are 5mm, 4mm, 3mm, and 2mm. The
vertical distances between two adjacent target line centers of the longitudinal branches are
4mm, 3mm, 2mm, and 1 mm.
B:
Dead zone target group. The center horizontal distance of adjacent lines is 10mm, and the
distances to the acoustic window are 10mm, 9mm, 8mm, 7mm, 6mm, 5mm, 4mm, and 3mm.
C:
Vertical target group 19 target lines with a 10mm center distance between adjacent lines.
D:
Horizontal target groups. It contains 7 target lines, and the center distance between two
adjacent lines is 20mm.
• Simulated lesion
E:
Pseudotumor. It is located at the depth of 70-80mm, has a cylindrical shape and a diameter of
10mm, and is parallel to the target line in axial direction.
F:
Pseudocyst and stone. The pseudocyst is cylindrical, has a diameter of 10 mm, is located in
the depth of 70-80 mm, and parallel to the target line in axial direction. The stone has an
irregular shape, is located in the middle of the pseudocyst, and has a maximum size of about
4-6mm.
G:
Pseudocyst. It is located at the depth of 47-53 mm, has a cylindrical shape and a diameter of 6
mm, and is parallel to the target line in axial direction.
