Pelvimetry pelvic examination can be used for pregnant women to assess the size of the birth canal and pelvis. By measuring the size of the birth canal and the position of the pelvis, it can assess the potential risk of childbirth. This paper explores whether the use of digital imaging tools can replace traditional examinations, using digital imaging tools to measure the pelvis, and then using the data to perform statistical conversion to obtain the corresponding numerical formula, and compare it with traditional photography methods. Obtaining the same results, but for radiologists, how to quickly and efficiently obtain images with diagnostic value is the best way.
