四維放射治療技術(shù)4D-CT重建技術(shù)在肝癌精確放療定位的應(yīng)用效果分析
[Abstract]:Objective to observe the effect of 4D-CT reconstruction in accurate radiotherapy of liver cancer. Methods from July 2010 to July 2015, 52 patients with liver cancer were randomly selected from the oncology department of our hospital to receive the treatment and voluntarily accepted this experiment. All the patients were treated with radiotherapy, and all the patients were treated with radiotherapy. The four dimensional radiotherapy technique 4D-CT reconstruction was applied to radiotherapy. After the course of treatment was completed, the clinical efficacy of the patients was observed and analyzed. Results after treatment, the patients' condition was effectively controlled. The volume of the target area of 3D-CT was (245.7 鹵120.6) cm ~ (3) C ~ (3) C ~ (4) 路cm ~ (3), the volume of the two targets was (150.8 鹵127.8) cm ~ (3), the difference of the two targets was statistically significant (P0.05). In addition, there was no statistical significance between the 3D-CT target and 4D-CT target on the XY Z coordinate axis (P0.05). Conclusion the application of 4D-CT reconstruction technique in accurate radiotherapy of liver cancer is obvious. It can accurately judge the volume of target area, reduce the incidence of loss of target area, and reduce the extension of target area effectively. It is of great significance to the improvement of clinical curative effect and has high clinical value and extensive popularization value.
