APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The transverse diameter is the distance between the two innominate lines at their widest point, measuring approximately 13 cm. The entrance of the fetal head into the pelvic excavation normally takes place through a rotation from the oblique diameter to the transversal diameter.

Detailed explanation-2: -The diameters of the outlet of the pelvis are two, antero-posterior and transverse.

Detailed explanation-3: -The diameter of transverse reinforcement of columns should be equal to one-fourth of the diameter of the main steel rods but not less than.

Detailed explanation-4: -The diameter of the transverse reinforcement (links, loops or helical spiral reinforcement) should not be less than min or one quarter of the maximum diameter of the longitudinal bars, whichever is the greater.
