利用 PACS 系统行乳腺癌术后放疗胸壁切线野的设计

摘要

Objective:Use PACS system to design the tangential chest wall field after modified radical mastectomy on breast carcinoma. Methods:The CT images of Patient after modified radical mastectomy on breast carcinoma were uPloaded to doctor's workstation through PACS system,then the tangential chest wall fields were determined with tools such as ″ drawing″ ,″ distance measure″ ,and ″ angle″ on window of PACS system in order to ensure the CLD was less than 3cm. Results:All CLDs of tangential chest wall fields of 30 Patients after modified radical mastectomy on breast carcinoma were less than 3cm. No radiation Pneumonitis occurred after radiotheraPy. Conclusion:APPlication of PACS system to design the tangential chest wall field can ensure the lowest rate of radiation Pneumotis,it also can reduce oP-erating time and imProving resource useful rate.%目的：利用 PACS 系统设计乳腺癌术后放疗胸壁切线野。方法：30例乳腺癌改良根治术后需行放疗的患者经过胸部 CT 扫描后，在医生工作站 PACS 系统上传的 CT 图像上，利用 PACS 系统窗口提供的“划线”、“距离测量”、“角度”等工具，确定胸壁切线野的大小和角度，并保证肺受照厚度（ CLD）﹤3cm。结果：30例乳腺癌术后患者胸壁切线野的肺受照厚度（ CLD）均﹤3cm，无1例在照射过程和照射后发生放射性肺炎。结论：利用 PACS 系统设计乳腺癌术后放疗胸壁切线野，可以保证放射性肺炎的发生降低到最低点，并缩短定位时间，患者感觉更加舒适耐受，减少医患压力，提高了工作效率和资源的利用率。
