Patented Quadric lighting reflection, 120 degrees LED beam angle;
专利二次反射照明，120度LED光束角；
In addition, beam Angle optimization can also optimize dose distributing of lung cancer to improve therapeutic effect.
另外肺癌放疗的角度优化也可以优化靶区剂量分布，提高治疗效果。
Conclusions: the beam Angle and the number of beams have influence upon dose distribution, the dose distribution would be improved for large volume target with the increment of beam number.
结论：照射野方向和照射野的数目对剂量分布有影响，增加照射野的数目可以改善体积较大的病灶的剂量分布。
