Abstract

Why use three-dimensional (3D) reconstruction techniques for quantitative analysis of intracoronary ultrasound (ICUS) images? In clinical practice an ICUS catheter is used to examine and investigate a segment of a coronary vessel by moving the catheter manually forward and backwards. Since ICUS images show only very thin cross-sections of the vessel, it is difficult for the observer to mentally build up a 3D representation of the investigated segment. Digitisation of a stack of two-dimensional (2D) cross-sectional images (e.g. a tomographic image data set) enables 3D computer reconstruction. From this 3D reconstruction several 2D cut-planes through the coronary vessel can be computed, also known as longitudinal views (L-views) (Mintz et al. 1993, 2001; DI Mario et al. 1995; Roelandt et al. 1994; Rosenfield et al. 1991; VON Birgelen et al. 1995b). The role of ICUS for serial studies and quantitative measurements is well appreciated (Nissen and YocK 2001; Slager et al. 2000; Sousa et al. 2001; Takagi et al. 1999). An L-view also makes it easier to re-study and analyse segments in follow-up studies. Further-more, measurements of the target area (lesion and stent lengths) are easily obtained from L-views.
