Accuracy and reproducibility of a newly developed tool for volume measurements of the arm using 3D stereophotogrammetry

Lymph edema of the arm is a common complication after breast cancer treatment. To evaluate lymph edema volume and treatment outcome, an easy to use, objective quantification method of arm volume is necessary. Most of the times, water displacement is used to measure arm volume, as it is an easy and robust method that can be performed at any place with some simple equipment. However, when using water displacement, no exact localization of volume differences can be seen. To accurately measure hand and forearm volume separately, an in house developed device was made for accurate landmark placement.
