Abstract

This study presents a novel method for 3D imaging of tubular structures, such as blood vessels and catheters. With this method, the 3D object is reconstructed from three mutually exclusive orthogonal projections of the same volume. This triplanar projection imaging (TPI) was evaluated on a phantom filled with T1-shortening, Gd-based contrast agent embedded into a matrix. The projected structures were segmented out on each one of the projections and a backprojection algorithm was used to generate a rendering of the tubular structure in 3D. The accuracy of the method was investigated by comparing the centerline of the 3D tubular structure generated from TPI with the centerline extracted from a multislice set of images of the same volume. The two tubular structures were well matched in 3D. With further optimization and reduction of acquisition time, this method can be used for 3D fast imaging of interventional tools or blood vessels with applications in interventional MRI.
