The measurement errors on various marker positions with VECTRA H1 and the breast model

Using a female breast model, Three, 5, or 7 markers were attached when photographing with VECTRA H1, with lateral markers 6 cm from the midline. Five markers were configured in two ways, with the lateral markers either positioned 3 cm outside the midline (narrow) or 9 cm outside the midline (wide). Models were created three times under each condition, for a total of 15 models. Differences (measurement error) between measured values on 3D models and actual measured values on the physical model were verified for six distances, such as distance between the nipples. X: Sternal angle; Y: intersection of right anterior axillary line and Inframammary fold; Z: intersection of left anterior axillary line and breast descending line; N(r): right nipple; N(l): left nipples,
