應(yīng)用CTVision治療胸腹腫瘤中呼吸運(yùn)動(dòng)影響的研究
[Abstract]:Objective radiotherapy is an important method in the treatment of chest and abdomen tumors, and respiratory movement is one of the main factors affecting radiotherapy of chest and abdomen tumors. Because of the existence of respiratory movement, the radiation field can be enlarged and the coincidence between the radiation field and the tumor target is poor, which affects the accuracy of radiotherapy. Many experts and scholars have studied many methods to control respiratory movement, but these methods have more or less shortcomings in clinical application. Methods of controlling respiratory movement need to be further studied. In the present situation, CTVision and the simulated respiratory movement mould designed and made by ourselves were used to explore the deformation of the direction of head and foot affected by respiratory movement on the chest and abdomen tumor, and without 4D-CT, the deformation of the head and foot direction of the chest and abdomen tumor was investigated. CT was used to detect the margin of tumor amplitude (head and foot direction) to provide the basis for drawing tumor target and how to revise the plan, and to verify the accuracy and correctness of the treatment. Materials and methods the experimental group used the simulated respiratory movement mould designed and made by ourselves. The center diameter 3mm steel ball and the diameter 40mm ball were placed on the mould tray. The center was turned on and the wooden ball was made 18 times per minute by turning on the power supply. The total length 2cm round-trip motion. CT scans the motion state image with a thickness of 3 mm and random scanning for 4 times. The image is transmitted to the planning system to compare the change of tumor location make the treatment plan verify and observe the deviation value. The dose deviation between the edge of PTV and the center of GTV was calculated. From March to December 2012, 21 patients with chest and abdominal tumors were collected in the case group. The respiratory motility of each patient was measured and recorded under the analogue positioning machine before localization. The same range was scanned at random twice, and the thickness of the layer was 5 mm. The images were transmitted to the planning system. According to the characteristics of lung cancer and liver cancer, the treatment plan was made and three dimensional conformal radiotherapy was performed, which was verified regularly during the treatment. Each patient was verified at least 3 times, and the deviation was observed. The results of the case group and the experimental group were compared. Results the measured deformation diameter of the tumor was within the theoretical maximum deformation diameter, and the tumor could move to any position within the theoretical maximum deformation diameter. The mean deviation value of the experimental group was less than that of the respiratory motility (tr-10.78, P0, P0. 05). In the case group, the mean value of the verification deviation of the patients with FGG and PQQ is lower than that of the respiratory motility. There is no significant difference between the mean value of the validation deviation and the respiratory motility in the), e group (P0. 05), e group is 0, so it is not possible to carry out the statistical test for the patients with P0. 05), e group because of the standard deviation is 0. 5%), and there is no significant difference between the two groups (P0. 05), e patients can not carry out statistical test because of the standard deviation is 0), and there is no significant difference in the mean value of the validation deviation between the two groups. In group d, the mean value of validation deviation was greater than that of respiratory motility (P0. 05). Conclusion 1. Under the influence of respiratory movement, tumor can move anywhere in the range of respiratory motility. 2GTV extranasal 15mm and extranasal 20mm showed that the measurement deviations were 3.705% and 4.07%, both of which were less than 50.5%. It shows that the measurement deviation is within the acceptable range. 3. When the verification deviation value is within the respiratory movement range value, there is no need to revise the treatment plan, and the verification deviation value exceeds the respiratory movement range value. The treatment plan should be revised. 4. The radiotherapy plan made and executed by CTVision is accurate and accurate.
