3D object volume measurement using freehand ultrasound

Abstract

Algorithms for volume evaluation of 3D objects on freehand ultrasound images are considered. The position sensor used provides image spatial position and orientation data. The algorithms are based on Watanabe formula for volume computation and use cubic spline interpolation. They allow object volume evaluation on initial image sequence without reconstruction of 3D cube avoiding inevitable data loss at this pre-processing stage. The algorithm accuracy was tested on simulated and real objects. © Springer-Verlag Berlin Heidelberg 2005.
