为精确治疗，我们建议应测量楔形野的剂量数据。
We suggest the measurement of wedge field depth dose for the accurate dosimetry.
目的：探讨楔形野深度和射野大小对楔形因子的影响。
Objective:The effects of depth and field size on wedge factors were studied.
方法：利用电离室法测量平野、动态楔形野、物理楔形野的深度剂量和射野外周边剂量。
Methods: The depth doses and peripheral doses were measurement for open field and Enhanced Dynamic wedge field as well as physical wedge.
