Description
Technical Field
The invention belongs to the technical field of medical treatment, and particularly relates to an experimental system for simulating measurement of prostate movement in vivo.
Background
At present, radiotherapy technology is still an effective means for clinically treating cancer. In order to effectively kill tumor cells during radiotherapy, the traditional method is to enlarge the external boundary of the tumor so that the tumor area can be completely irradiated by rays, but the normal tissue cells are damaged, and postoperative complications are easy to cause. Researchers have also proposed in succession that respiratory gating techniques, four-dimensional stereotactic radiotherapy, and the like may be used to compensate for the patient's respiratory motion. However, there are some uncertainties in radiotherapy of prostate tumors, and the unresolved problem is that bladder fullness can also cause prostate displacement, which can affect the positioning accuracy of the prostate. Although mechanical fixation can be used to limit the movement of the prostate due to bladder filling, it can also damage the patient's body, thereby affecting the patient's therapeutic effect. Therefore, it is necessary to consider the effect of bladder fullness on prostate position when performing clinical surgical radiotherapy.
Based on the current situation, it is very important to design an experimental system for simulating measurement of prostate movement in vivo. The experimental system can be used for exploring the prostate motion change rule caused by bladder filling degree, and is favorable for improving the radiotherapy precision of the prostate cancer. In addition, the motion data of the prostate can be collected, and certain data support can be provided for researchers.
