Establishment of a biostereometric system for measurement of breast volume / 中华医学美学美容杂志

ABSTRACT

Objective To establish the biostereometric system of breast volume measurement and to estimate the precision and reliability of the designed system. Methods Biostereometric system of breast volume measurement was built upon the biostereometrics based on computer stereo vision and image processing. One laser projector was used as illuminating source, two CCD cameras were mounted for photo-taken, a series of parallel points were provided through a piece of grating. The volumes of 12 female breast models were tested by water displacement (golden standard) and biostereometric analysis. Results The maximum size of marks we photographed was within 120 mm?140 mm?80 mm. The characters of the system was rapid, non-contact and noninvasive. The validity and reliability of determination of breast volume between biostereometric system and golden standard had no significant difference, compared to water displacement (P=0.473). Conclusions Biostereometric system of breast volume measurement will be suited for the clinical application. The study offers a noninvasive, non-contact, rapid and accurate morphologic method and provides a new theory foundation for morphological analysis.
