Densitometry of the x-ray image provides a suitable technique for clinical quantification of the urethral shape during all stages of voiding. The technique of cystourethrographic densitometry is applied to determine the cross-sectional shape of the human female urethra during various phases of voiding. Errors that may occur because the x-rays are not perpendicularly incident to the urethral plane are considered and a method for their minimization is indicated.
X射线图像密度测定法提供了一种适用于临床量化排尿各阶段尿道形态的技术。膀胱尿道造影密度测定技术用于确定女性在排尿不同阶段尿道的横截面形状。考虑了因X射线未垂直入射到尿道平面而可能出现的误差，并指出了将这些误差最小化的方法。
