Embodiment 1
[0040] Such as figure 1 Shown, present embodiment provides a kind of preparation method of artificial bone, comprises the following steps:
[0041] S101. Acquire medical image data of a bone injury site of a patient.
[0042] S102. Obtain the original bone model diagram of the patient's bone injury site according to the medical image data, perform image processing on the original bone model diagram, and extract the surface grid intersection of the original bone model diagram, and the surface grid intersection point and The embedded free points are connected into a line, and a microstructure diagram is formed according to the formed line to create a three-dimensional porous model diagram.
[0043] S103. Prepare a three-dimensional porous artificial bone according to the three-dimensional porous model diagram.
[0044] In this embodiment, a three-dimensional porous model diagram is established through the acquired medical image data of the patient's bone injury site, and then ...
Embodiment 2
[0046] Such as figure 2 As shown, this embodiment provides a method for preparing an artificial bone, and several steps are added on the basis of Embodiment 1, including:
[0047] S201. Acquire medical image data of a bone injury site of a patient.
[0048] Specifically, CT or MRI is used to perform a thin-slice scan on the injured part of the patient, the thickness of the thin-slice is 0.625 mm, and the format of the medical image data is DICOM3.0.
[0049] S202. Obtain an original bone model diagram of the patient's bone injury site according to the medical image data.
[0050] In this embodiment, the CT or MRI image data of the patient's bone injury site is imported into the computer's three-dimensional reconstruction software, and the attenuation of X-rays by substances is reflected according to the gray value of the CT of the human body. For example, the gray value of water is defined as 0, and the gray value of fat is defined as 0. The CT value is -100, and the cortic...
Embodiment 3
[0073] Such as image 3 As shown, this embodiment provides a preparation system for artificial bone, and this embodiment corresponds to the method in Embodiment 1, including:
[0074] The data acquisition module 310 is configured to acquire medical image data of the patient's skeletal injury site.
[0075] The model creation module 320 is used to obtain the original bone model diagram of the patient's skeletal injury site according to the medical image data, perform image processing on the original bone model diagram, and extract the surface grid intersection of the original bone model diagram, the The intersection points of the surface mesh and the embedded free points are connected to form a line, and a microstructure diagram is formed according to the formed line, and a 3D porous model diagram is created.
[0076] The artificial bone preparation module 330 is configured to prepare a three-dimensional porous artificial bone according to the three-dimensional porous model di...
