Embodiment approach

[0104] First, according to the movement rules of tumors or normal organs of the human body, five different motion trajectories are set in advance, represented by numbers 0, 1, 2, 3, and 4. When setting the motion trajectories, it can be realized by modifying the numbers representing different motion trajectories. . The specific steps during operation are as follows:

[0105] Step (1): Place the simulated tumor or organ in the scanning area of ​​the system, and then determine the mathematical curve or table according to the actual motion characteristics of the tumor or organ;

[0106] Step (2): According to the mathematical curves and tables representing the three-dimensional motion law of the simulated object, analyze in the three-dimensional direction, so that the time motion parameters in the three directions are respectively formed;

[0107] Step (3): Load the time motion parameters in three directions into the control device part;

[0108] Step (4): Then turn on the main...

Abstract

The invention discloses a medical three-dimensional simulation moving platform and a simulation moving method thereof. The platform comprises a precise numerical control work table which is respectively connected with an X-direction stepping motor, a Y-direction stepping motor and a Z-direction stepping motor in the X direction, the Y direction and the Z direction, wherein the X-direction stepping motor is connected with an X-direction stepping motor driver, the Y-direction stepping motor is connected with a Y-direction stepping motor driver, the Z-direction stepping motor is connected with a Z-direction stepping motor driver, and the X-direction stepping motor driver, the Y-direction stepping motor driver, the Z-direction stepping motor driver and the precise numerical control work table are connected with a control device. A verifying method includes two parts: firstly, a target section confirming method of common abdmen-thorax tumours is verified through a three-dimensional moving model, defects of various methods are analyzed by comparing with objective real objects, and corresponding improving strategies are researched; and secondly, by simulating motion rules of the tumours and endangered organs, deformation rules of the tumours and the endangered organs caused by breathing movement are reaserched, and influences on tumour exposure dose accurate calculation from local electron concentration changes caused by the deformation rules are researched, and objective foundation is further provided for accurate assess and accumulation of a target section and the endangered organs.

Description

technical field [0001] The invention relates to the field of tumor radiotherapy medical equipment, in particular to a medical three-dimensional simulation motion platform and a simulation motion method thereof. Background technique [0002] At present, malignant tumors have posed a serious threat to human health. As one of the three major treatment methods for malignant tumors, radiation therapy contributes about 40% to the cure of malignant tumors. However, the curative effect of traditional radiation therapy is poor, mainly because there are often some organs at risk that are more sensitive to radiation around the tumor lesion, which limits the further increase of the radiation dose in the tumor area. Modern precision tumor radiotherapy technologies, such as 3-dimensional conformal radiation therapy (3DCRT) and intensity-modulated radiation therapy (IMRT), can accurately formulate radiotherapy plans through precise tumor target delineation, and Accurate implementation of...
