Abstract

In Magnetic Resonance Imaging (MRI) selective enhanceitient of different features can be achieved by emphasizing the contrast of tissues with either long spin-spin relaxation time (T2) or short spin-lattice relaxation time (T1) . The contrast level is affected by the repetition tune (TR) and the echo time (TE) used in multiple spin-echo (MSE) iaethod. In this study anatomical structures of brain tissues are simulated by fractal geometry techniques and these images are then used to simulate MR images with different contrast levels. It is shown that the fractal grown brain slice gives a much closer resenthlance than a geoiaetric phantom and provides greater flexibility in simulating complicated structures. The fractal grown brain slice provides a computer generated phantom which is more suitable for simulating selective contrast enhancement in MRI. 1.
