【摘要】 本文在l00个完整颅骨上,除了一般地观测了卵圆孔的形态和位置外,特别对影响X线投照较大的卵圆孔管深和倾斜度(简称倾角)作了细致的测量,并与各标本的相应颅底片进行对照比较,讨论卵圆孔诸形态特征对X线投照的影响。管状卵圆孔的平均倾角值为28.1±10.1°。在摄取以显示卵圆孔为主的颅底片时,本文建议:中心X线的投照角可优先在倾角平均值的范围内选取。更多还原

【Abstract】 The depth and inclination(i. e. inclining angle) of the foramen ovale in 100 cases of dry skull specimen were studied and measured besides general observation of the shape.size and location of the foramen ovale. The appearance of the foramen ovale of every skull film in basal projection was also compared with that of corresponding specimen.The various morphological characteristics of the foramen ovale which affect the radiogra-phic demonstration were discussed.更多还原
