Abstract
Using the method in accordance with the invention a layer of an object is selected by means of a cycle comprising a non-selective 90.degree. pulse, a dephasing gradient magnetic field, a non-selective 180.degree. pulse and a selective 90.degree. pulse in the presence of a similar gradient field. In the layer, a magnetization in the z-direction is obtained. Outside the object layer the transverse magnetization is totally dephased. By executing the cycle three times, during which the gradient directions of the three gradient fields used are mutually orthogonal, a 'cube-like' volume is selected. High-resolution images of spin density distributions and T1 or T2 distributions can thus be realized and location-dependent spectroscopy is also possible.
