Patient-Specific Parametric Models of the Gravid Uterus and Cervix from 2D Ultrasound: Models

This file contains solid models of human uteri and cervices built using patient-specific measurements from an ultrasonic longitudinal study of maternal anatomy. The anatomical measurements were taken by 3 trained sonographers from 2D ultrasounds of the uterus in the sagittal and axial view and the cervix in the sagittal view. Measurements were collected at 4 gestational ages (8-13, 14-16, 22-24, and 32-34 weeks) from 29 patients who delivered at term in the supine and standing positions. The models were built using Solidworks 2018-19 (Dassault Systemes, Vélizy-Villacoublay, France). The Model Data folder is organized by patient and contains .stl files corresponding to patient, visit, position, and sonographer. Each file is the resulting solid model of the uterus and cervix from the dimension measurements – see manuscript for methods. The name of the file indicates the patient number, the visit, the position, and the sonographer. For example, p24v3supine_s1 corresponds to patient 24’s third visit, when scanned in the supine position, with measurements taken by sonographer 1. For models that failed to build, a .txt file is included with reason for failure – see manuscript for a description of failure modes.
