一、 医用电子加速器的射线能量从低能向中高能机的方向发展


YOUYUFANGLIAOYISHENGZAIZUOFANGLIAOJIHUADESHIHOUTEBIEGUANXINDESHISHEXIANDEFUSHESHENDUTEXING,ZHEIZHIJIEDAOZHILEXSHEXIANNENGLIANGXIANGZHONGGAONENGFANGXIANGFAZHAN。ERJIASUQISHEXIANNENGLIANGZI6MVXIANG14MVSHENZHI20MVFAZHANYILAI,MUQIANZAIZHONGGUOGUONEIZHONGGAONENGJIDEPUJISUDUYEHENKUAI。


中高能机与低能机相比,在加速器能量层级和为放疗医生提供的治疗手段上均有质的不同。低能机只能提供单能的X射线(4MV或6MV),而中高能机不仅能够提供一档到两档的X射线,还能提供不同能量档次的电子线。目前市面上一般把只能提供一档X射线的机器称为单光子,能够提供两档X线的机器称为双光子,以此类推为三光子、多光子等等。


发展中高能机的根本目的不在于X射线能量的提高,而在于电子线在临床上的应用需求。福彩3d跨度走势图对于电子线而言,低能的6MV加速器,原则上也能引出6MeV的电子线,但是6MeV电子线在临床上基本上没有什么意义,中高能机的发展,使得电子线的能量提高到大于10MeV,从而具有医学应用价值,应该说,这才是中高能机的真正意义所在。

2) 立体定向放射治疗(SRT)技术

3) 三维适形放射治疗(3DCRT)技术

4) 调强放射治疗(IMRT)技术

一般来说,SRS和SRT只适应于用线束来对头部或体部的球状小肿瘤进行治疗,而3DCRT和IMRT是用锥形束或扇形束来治疗各部位较大的肿瘤IMRT甚至能治疗形状怪异很不规则的肿瘤福彩3d跨度走势图。据报道调强技术在美国2003年才开展迅速的发展起来,至今带有IMRT功能的放疗设备普及率已高达70%。

缺点:治疗时间长,因此必须克服器官运动的负面影响。而且即使步进精度非常好,断层衔接非常好,也可能由于器官的运动使得治疗区有时进入治疗断层,有时脱离治疗断层,从而在断层衔接区出现过剂量或欠剂量的情况。
