摘要：

A projection-operator technique is applied to a general three-component model for magnetization transfer, extending our previous two-component model [R. S. Adler and H. N. Yeung, J. Magn. Reson. A 104, 321 (1993), and H. N. Yeung, R. S. Adler, and S. D. Swanson, J. Magn. Reson. A 106, 37 (1994)], The PO technique provides an elegant means of deriving a simple, effective rate equation in which there is natural separation of relaxation and source terms and allows incorporation of Redfield-Provotorov theory without any additional assumptions or restrictive conditions, The PO technique is extended to incorporate more general, multicomponent models, The three-component model is used to fit experimental data from samples of human hyaline cartilage and fibrocartilage, The fits of the three-component model are compared to the fits of the two-component model.
