Aim. The aim of the study was to study the basic forms of the muscle structure that lifts the anus in men and women of the first and second adult periods and the older age group according to CT and MRI data. Material and Methods. in our work we used data from computer and magnetic resonance tomograms of 57 patients aged 20 to 70 years. In the «Autoplan» system using a precision technique in semi-automatic mode, three-dimensional models of the muscle that lifts the anus are created. Results and Discussion. The results of the research: three-dimensional models of the muscle that lifts the anus are created and described: for young women and men of all ages, the keel-shaped and funnel-like shape of the muscle that raises the anus is characteristic; and for women of advanced age - horseshoe. Conclusions. The creation of three-dimensional models of a muscle that lifts the anus using the Autoplan system allows not only studying the anatomy of the investigated area in vivo, but also planning the course of operations, especially with the use of reticular implants, using the non-exhaustive methods of surgical correction of the pelvic floor. The disadvantages of this method include the inability to conduct research in an upright position (modern computer and magnetic resonance tomographs in Russia are designed for examining patients only in a horizontal position), as well as the impossibility of automatic segmentation in view of the low contrast of this area, which requires work only in manual mode, and this does not exclude the error in the study.
