Objective To investigate the value of Adobe Photashop images software in the verifica-tion of radiation portal. Methods The portal and simulation films or CT reconstruction images were impor-ted 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 com-parison between portal image and simulation image, the set-up errors in right-left, superior-inferior and ante-rior-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) mm and (1.67 ± 0.68)mm in the abdomen; (1.93 ± I. 83) mm, (1.59 ± 1.07)mm and (0.85 ± 0.72)mm in the pelvic cavity. Conclusions Accurate radiation portal verification and posi-tion measurement can be completed by using Adobe Photoshop, which is a simple, safe and reliable method.
