【摘要】：目的观察四维放射治疗技术4D-CT重建技术在肝癌精确放疗定位的应用效果。方法随机性地选择2010年7月至2015年7月期间来我院肿瘤科接受治疗并自愿接受本次实验的52例肝癌患者,使其成为本次实验的研究对象,对所有患者均采取放疗治疗,并将其四维放射治疗技术4D-CT重建技术应用在放疗手段中,疗程完成后,对患者的临床里疗效进行观察与分析。结果通过治疗后,患者的病情均得到了有效的控制,通过比较得知,3D-CT靶区的体积是(245.7±120.6)cm3,4D-CT靶区的体积是(150.8±127.8)cm3,两个靶区的体积表现出明显的差异,数据差异具有统计意义(P0.05)。另外3D-CT靶区以及4D-CT靶区在X、Y、Z坐标轴上比较,数据差异无统计意义(P0.05)。结论四维放射治疗技术4D-CT重建技术在肝癌精确放疗定位的应用效果比较明显,可对其靶区体积进行准确地判断,降低靶区丢失的发生率,使其外扩范围得到有效的减少,对其临床疗效的提高有着显著的意义,临床价值较高,具有广泛推广的价值。
[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 卤120.6) cm ~ (3) C ~ (3) C ~ (4) 路cm ~ (3), the volume of the two targets was (150.8 卤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.
