One of the major disadvantages of MRI is its image distortion, which affects the accuracy of the localization of SRT and the veracity of the dose distribution.
对MRI而言,由于存在着影像扭曲的问题,因此影响了SRT定位的精确性,并进一步影响了剂量分布的准确性。
But one weakness of MRI is the problem of image distortion, which causes the position of the targets to partial move, and .
但MRI自身又有其缺点,即存在影像扭曲的问题,可能导致靶区和周围正常组织的相对位置发生偏移,进而影响了剂量分布的准确性和治疗的结果。
