Abstract

Three-dimensional reconstruction of CT images is of great value, particularly for the study of complex fractures. However, most commercially available three-dimensional imaging systems use thresholding techniques, where partial volume effects in the individual voxels can lead to fractures being missed, or the creation of spurious bone defects. This article describes a volumetric rendering technique for three-dimensional CT images, with percentage representation which shows thin structures with varying degrees of translucency. In this way, small fractures are clearly shown while the integrity of very thin objects is preserved. Furthermore, bone and soft tissue are clearly differentiated. The advantages of the technique are illustrated by images obtained in the examination of pelvic trauma.
