During the period 1988-1991, 23 patients with prostatic carcinoma were treated by transperineal iodine seed implantation guided by transrectal ultrasound. We introduce a refinement of the implantation technique using a rigid column of seeds and spacers. The uniformity parameter based on the peak width of the natural volume-dose histogram demonstrated quantitatively that this refinement resulted in a more accurate seed arrangement.
在1988年至1991年期间，23例前列腺癌患者接受了经直肠超声引导下的经会阴碘籽植入治疗。我们介绍了一种使用刚性籽源柱和间隔物的植入技术改进方法。基于自然体积剂量直方图峰值宽度的均匀性参数定量显示，这种改进导致了更精确的籽源排列。
