Until recently, acquisition of accurate data concerning tumor anatomy lagged behind other developments in radiotherapy. With the advent of computed tomography (CT), these data can be displayed and transmitted to a treatment planning computer. CT information concerning tumor location, irradiated volume, and dosimetry were compared with results obtained by traditional methods. Of 201 consecutive patients examined, CT was found to be helpful in 36% (pelvic tumors, 48%; chest wall tumors, 2%; intrathoracic tumors, 54%; palliative treatment, 27%).
直到最近，获取有关肿瘤解剖结构的准确数据仍落后于放射治疗的其他进展。随着计算机断层扫描（CT）的出现，这些数据可以被显示并传输到治疗计划计算机中。将有关肿瘤位置、照射体积和剂量测定的CT信息与通过传统方法获得的结果进行了比较。在连续检查的201例患者中，发现CT在36%的患者中有用（盆腔肿瘤，48%；胸壁肿瘤，2%；胸腔内肿瘤，54%；姑息治疗，27%）。
