60Co治疗机在放射治疗中有着悠久和辉煌的历史,是重要的放疗设备。如今,放疗已进入精确定位、精确计划、精确治疗的“三精”时代,适形放疗与60Co治疗机相结合可谓给60Co治疗机注入了新的活力,可以实现精确放疗,有利于提高治疗增益比。为了更好地达到“三精”要求,提出了增加源轴距、提高源的活度、校正源传输的端效应及致力提高国内放疗设备的质量和水平等建议。
The 60Co therapy machine has a long and brilliant history in radiation therapy and is an important radiotherapy equipment. Nowadays, radiotherapy has entered the era of “three precisions” of precise positioning, precise planning, and precise treatment. The combination of conformal radiotherapy and 60Co treatment machines has injected new vitality into the 60Co treatment machine, enabling precise radiotherapy, and improving the treatment gain. ratio. In order to better achieve the “three fine” requirements, proposed to increase the source wheelbase, increase the activity of the source, correct the end effect of the source transmission and to improve the quality and level of domestic radiotherapy equipment and other recommendations.
