The technical solution adopted for the present invention to solve the technical problems is: a kind of ultrasonic body mould, the shell that comprises rigid material, be characterized in: in the shell of rigid material, at least successively put into one deck support member, the thin piece of biomimetic material from the bottom up, the hollow space between the thin piece of support member and biomimetic material has filled up liquid ultrasonic biomimetic material.
The thin piece of biomimetic material is little by acoustic attenuation coefficient, and the approaching polythene material of acoustic impedance characteristic and tissue is made.
On the thin piece of described biomimetic material of top layer, be placed with the probe locating piece, and on the probe locating piece, have the probe locating hole.
The size dimension of probe locating hole is greater than the size of ultrasound probe, and when calibrating, described ultrasound probe places the probe locating hole, and is close on the thin piece of described biomimetic material of top layer.
Have at least one pair of hand-hole and steam vent in addition on the probe locating piece as the ultrasonic biomimetic material of liquid state.
On the thin piece of each described biomimetic material, liquid ultrasonic biomimetic material enters in the corresponding cavity by the hand-hole of each liquid ultrasonic biomimetic material.
The thickness of the thin piece of biomimetic material is identical with the simulated humanbody thickness of tissue with the height of support member.
Thin upper and lower two surfaces of piece of biomimetic material are parallel to each other, and upper and lower two end faces of described support member also are parallel to each other.
The invention has the beneficial effects as follows: the maching dimension of thin piece of biomimetic material and support member is accurately controlled easily in the phantom, and precision can not lost in the assembling process, easily the parameters,acoustic of strictness control phantom.This phantom is the accuracy of detection height not only, has simulated the layer structure of tissue, and easy to make simple, with low cost, can improve the popularity of phantom.
