Abstract

Magnetic resonance techniques are widely used in biological materials that have lots of moistures. In this study, we examined the magnetic resonance properties of dried Korean red ginseng. Relaxation time constants, spin-lattice and spin-spin relaxation time constants, of various grades of red ginsengs were measured and analyzed. Also free induction decay signals were obtained and analyzed. Internal physical information was obtained nondestructively from normal and abnormal red ginsengs using a magnetic resonance imaging (MRI) system. Single point imaging technique was used to image dried red ginsengs. Various types of internal defects were visualized and analyzed. MR techniques suggested ways to examine dry materials effectively.
