**Core Concept**
Pelvimetry is a radiological assessment of the pelvic dimensions to evaluate the suitability of the pelvis for vaginal delivery. It is a crucial diagnostic tool in obstetrics, especially in cases where there is a concern about fetal cephalopelvic disproportion or other obstetric complications.

**Why the Correct Answer is Right**
Pelvimetry is typically performed to assess the pelvic inlet, midpelvis, and outlet dimensions. It is essential in cases of dystocia (difficult labor), fetal malpresentation, or a history of previous pelvic trauma. The X-ray pelvimetry helps in planning the mode of delivery, whether it be vaginal or cesarean section.
