摘要
目的探讨利用Adobe公司Photoshop图像处理软件验证放疗位置的临床价值。方法利用扫描仪将加速器拍摄的验证片、定位片或数字重建图像输入计算机中,调整图像大小、灰度、对比度后进行图像配准与测量。结果通过射野验证图像与参考图像的对比发现,在左右方向、上下方向和前后方向头颈部摆位误差分别为(1.11±1.37)、(1.33±1.25)、(0.83±0.79)mm,胸部的分别为(1.44±1.03)、(1.6±1.52)、(1.34±1.17)mm;腹部的分别为(1.53±0.86)、(1.83±1.19)、(1.67±0.68)mm,盆腔部的分别为(1.93±1.83)、(1.59±1.07)、(0.85±0.72)mm。结论利用Adobe公司Photoshop图像处理软件可以进行射野和摆位位置的准确测量且操作简单、安全可靠。
Objective To investigate the value of Adobe Photoshop images software in the verification of radiation portal. Methods The portal and simulation films or CT reconstruction images were imported into computer using a scanner. The image size, gray scale and contrast scale were adjusted with Adobe Photoshop images software, then image registration and measurement were completed. Results By the comparison between portal image and simulation image, the set-up errors in right-left, superior-inferior and anterior-posterior directions were ( 1.11 ± 1.37) mm, ( 1.33 ± 1.25 ) mm and (0.83 ± 0.79) mm in the head and neck;(1.44±1.03) mm,(1.6±1.52) mm and (1.34±1.17) mm in the thorax;(1.53±0.86) mm,(1.83±1.19) mmand (1.67±0.68) mmintheabdomen;(1.93 ±1.83) mm,(1.59±1.07) mm and (0.85± 0.72) mm in the pelvic cavity. Conclusions Accurate radiation portal verification and position measurement can be completed by using Adobe Photoshop, which is a simple, safe and reliable method.
