Strain calculation from sinusoidal tagged MR images via Moire analysis
A simple algorithm is proposed for calculating strain directly from a tagged magnetic resonance (MR) image via Moiré analysis. Tagged MR images are used to obtain strains in internal organs, particularly myocardial strain. Although signal processing-based analysis has recently been investigated, the reliability of the strain can not be obtained. In the present paper, a simple, fast, and accurat...
متن کاملAnalysis of ovarian tumor pathology by Fourier Transform Infrared Spectroscopy
BACKGROUND Ovarian cancer is the second most common cancer among women and the leading cause of death among gynecologic malignancies. In recent years, infrared (IR) spectroscopy has gained attention as a simple and inexpensive method for the biomedical study of several diseases. In the present study infrared spectra of normal and malignant ovarian tissues were recorded in the 650 cm-1 to 4000 c...
متن کامل[Analysis of colonic motility by fast Fourier transform].
Colonic motility curve was continuously recorded in dog using a strain gauge force transducer and the curve was analyzed by fast Fourier transform. (1) The basic pattern of the colonic motility curve was a gradually increasing and decreasing contractile wave. (2) The frequency components of the basic contractile wave showed a trimodal distribution with peaks at around 1, 20 and 80 mHz. (3) The ...
متن کاملPalmprint Identification by Fourier Transform
Palmprint identification refers to searching in a database for the palmprint template, which is from the same palm as a given palmprint input. The identification process involves preprocessing, feature extraction, feature matching and decision-making. As a key step in the process, in this paper, we propose a new feature extraction method by converting a palmprint image from a spatial domain to ...
متن کاملAngle-gathers by Fourier Transform
In this paper, we present a method for computing angle-domain common-image gathers from wave-equation depth-migrated seismic images. We show that the method amounts to a radial-trace transform in the Fourier domain and that it is equivalent to a slant stack in the space domain. We obtain the angle-gathers using a stretch technique that enables us to impose smoothness through regularization. Sev...
