“…We report a new multiscale topomorphologic opening method for separating two isointensity objects fused at different locations and scales due to limited resolution. One possible application may be the separation of vertebrae or other bone structures via low resolution computed tomography (CT) or magnetic resonance (MR) imaging of musculoskeletal systems [8], [9]. Other examples include tracking living cells in optical microscopic video imaging [10] or tracking moving objects/subjects in video imaging where multiple entities get mutually partially occluded from time to time.…”

A novel multiscale topomorphologic approach for opening of two isointensity objects fused at different locations and scales is presented and applied to separating arterial and venous trees in 3-D pulmonary multidetector X-ray computed tomography (CT) images. Initialized with seeds, the two isointensity objects (arteries and veins) grow iteratively while maintaining their spatial exclusiveness and eventually form two mutually disjoint objects at convergence. The method is intended to solve the following two fundamental challenges: how to find local size of morphological operators and how to trace continuity of locally separated regions. These challenges are met by combining fuzzy distance transform (FDT), a morphologic feature with a topologic fuzzy connectivity, and a new morphological reconstruction step to iteratively open finer and finer details starting at large scales and progressing toward smaller scales. The method employs efficient user intervention at locations where local morphological separability assumption does not hold due to imaging ambiguities or any other reason. The approach has been validated on mathematically generated tubular objects and applied to clinical pulmonary noncontrast CT data for separating arteries and veins. The tradeoff between accuracy and the required user intervention for the method has been quantitatively examined by comparing with manual outlining. The experimental study, based on a blind seed selection strategy, has demonstrated that above 95% accuracy may be achieved using 25–40 seeds for each of arteries and veins. Our method is very promising for semiautomated separation of arteries and veins in pulmonary CT images even when there is no object-specific intensity variation at conjoining locations.

“…Radiographic imaging has been transformed over the last century with contrast studies and 3-D reconstructions (Lambrecht et al, 1995;Lambrecht et al, 1997;Pate et al, 1986). Application of these radiographic methods preoperatively to videoscopic surgery makes possible new approaches to treatment (Haase, 1998;Lambrecht et al, 1997;Marsh and Vannier, 1983;Pate et al, 1986;Wagner et al, 1996). Just as in medical practice, the future is now in medical education where computer-assisted instruction is popular (Levine et al, 1999).…”

“…Since the 3D images are reconstructed by computer software using the data obtained from contiguous non overlapping CT sections, it is obvious that movement dur ing the CT study can lead to marked deterioration in the quality of the 3D displays [11]. The kidney is a relatively mobile organ which may be displaced by movements of the diaphragm.…”
