Image-based morphometry of cells, tissues, and organs is an important topic in biomedical image analysis. We propose a novel method to characterize the morphological information that discriminates between two populations of morphological exemplars (cells, organs). We first demonstrate that the application of standard techniques such as Fisher linear discriminant analysis (FDA) can lead to undesirable...
Being able to segment the esophagus without user interaction from 3-D CT data is of high value to radiologists during oncological examinations of the mediastinum. The segmentation can serve as a guideline and prevent confusion with pathological tissue. However, limited contrast to surrounding structures and versatile shape and appearance make segmentation a challenging problem. This paper presents...
This paper presents a patient specific deformable heart model that involves the known electric and mechanic properties of the cardiac cells and tissue. The accuracy and efficiency of the algorithm was tested for anisotropic and inhomogeneous 3D domains using ten Tusscher's and Nygen's cardiac cell models. During propagation of depolarization wave, the kinetic, compositional and rotational anisotropy...
In this paper, a method for modeling the deformation behavior of organs and soft tissue is presented. The purpose is to predict the global deformation effect that arbitrary, time-varying external perturbations have on an organ. The perturbation might be caused by an instrument (e.g., through the surgeonpsilas grasping and pinching actions), or it might be from organ-organ, organ-body-wall collisions...
