Seed point is prerequired condition for tracking based method for extracting centerline or vascular structures from the angiogram. In this paper, a novel seed point detection method for coronary artery segmentation is proposed. Vessels on the image are first enhanced according to the distribution of Hessian eigenvalue in multiscale space; consequently, centerlines of tubular vessels are also en...

Soon after its introduction to Europe prior to 1570, potato crops started to suffer “degeneration” or “running off”. This was attributed to physiological changes in the cultivars due to continuous vegetative propagation (Salaman, 1970). It was not until the XIXth century that the true cause of degeneration was found to be due to diseases, especially those caused by viruses. Thus, for successful...

The Universe is magnetized. This is true on “small” length scales, such as in planets and stars, and over much larger scales, such as across the tenuous gas in galaxies and galaxy clusters and, possibly, the even more rarefied intergalactic medium. Physicists are fairly certain that these magnetic fields weren’t created in the big bang (the reason has to do with the symmetry of Maxwell’s equati...

We developed a discrete tomography method for prostate implant reconstructions using only a limited number of X-ray projection images. A 3D voxel volume is reconstructed by back-projection and using distance maps generated from the projection images. The true seed locations are extracted from the voxel volume while false positive seeds are eliminated using a novel optimal geometry coverage mode...

Peganum harmala (Zygophyllaceae) is an intriguing herb with a long history of medicinal use. Antifungal activity of P. harmala seed extract against certain fungal species was investigated in vitro. Antifungal activity of the extract of P. harmala seeds was investigated against several fungal species using in vitro agar dilution technique. The fungal species included: Microsporum canis, Microspo...
