Embodiment 1

[0044] In embodiment 1 of the system of the present invention:

[0045] The medical imaging 3D entity reconstruction system is a rotatable multi-nozzle 3D printer, which mainly includes X-axis orbit, Y-axis orbit, Z-axis orbit and multiple nozzle modules. On the mobile bracket, multiple nozzles are fixed on the module, and the mobile bracket moves vertically and longitudinally. The nozzle module is fixed on the A axis which is perpendicular to the X axis and parallel to the Y axis, and the nozzle module can rotate around the A axis.

[0046] The horizontal moving device includes a motor and a parallel shaft driven by the motor. The nozzle is fixed on the horizontal shaft, and both ends of the parallel shaft are connected with vertical shafts. The movement device composed of motor, parallel shaft and nozzle is relatively simple, with low failure rate and small precision error.

[0047] The nozzle module includes a brake motor, an A-axis driven by a motor, and a vertical rotat...

Embodiment 2

[0051] In embodiment 2 of the system of the present invention:

[0052] The medical image three-dimensional solid reconstruction system includes multiple nozzles, each nozzle is fixed on a vertical rotating device, and the rotating device is fixed on the guide rod and can move in the horizontal direction on the guide rod. The function of the vertical rotation device and the guide rod is to make the nozzle move in the X-Y plane and rotate in the vertical plane.

[0053] The nozzle can move anywhere in the horizontal direction through the horizontal moving device. The motor controls the printing platform to move in the vertical direction. So that the nozzle can reach the desired position. When working, select the required sprinkler head for motion control, and another sprinkler head on the same rotating device as the sprinkler head is in a standby state.

[0054] The horizontal moving device preferably includes a motor, a parallel shaft driven by the motor and a nozzle module...

Embodiment 3

[0095] In embodiment 3 of the inventive method:

[0096] Such as Figure 6 As shown, the three-dimensional entity of the human thigh is reconstructed. The femur is located in the thigh of the lower limb of the human body. The upper end participates in the formation of the hip joint to connect the pelvis, and the lower end participates in the formation of the knee joint to connect the tibia of the calf. It is the longest tubular bone in the human body and bears the upper half of the human body. Portion all weight. The femur is also one of the most common bones in orthopedics and plastic surgery. This model includes the femur, blood vessels and muscles at the femur. Bones, blood vessels, and muscles have the same function and structure, and the structure of blood vessels is complex, fragile and easy to break, requiring support materials. Therefore, the three-dimensional solid reconstruction of the femur requires four materials with different properties. Therefore, this equip...

Abstract

The invention discloses a medical image three dimensional entity reconstruction system and a reconstruction method thereof. The system comprises a horizontal moving device, a vertical lifting device and rotating devices. The horizontal moving device comprises two parallel shafts and a vertical shaft, and the two ends of the vertical shaft are slidably connected with the two parallel shafts correspondingly. The rotating devices are arranged on the vertical shaft and can move in the direction of the vertical shaft. A plurality of spray head modules are installed on the rotating devices and conduct rotating and angle adjusting under driven of the rotating devices. The vertical lifting device is arranged under the horizontal moving device and is provided with a printing platform capable of going up and down. According to the medical image three dimensional entity reconstruction system and the reconstruction method thereof, the precision of a formed workpiece and the working efficiency of a machine can be improved, much abundant information difficult to display through traditional imageological examination is provided for doctors, and comprehensive and intuitive bases are provided for personalized treatment plans.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a medical image three-dimensional entity reconstruction system and a reconstruction method thereof. Background technique [0002] The three-dimensional reconstruction technology of medical images refers to the technology of reconstructing three-dimensional image models by using a series of two-dimensional slice images and performing qualitative and quantitative analysis. With the successful development and use of computerized tomography and nuclear magnetic resonance equipment, it provides doctors with clear tomographic image information of rich tissues and organs inside the human body, and assists doctors to diagnose diseases more intuitively, quickly and accurately. The existing three-dimensional imaging reconstruction system for medical imaging mainly reconstructs human organs and tissues based on two-dimensional sequence images obtained by medical imaging methods such as ...
