摘要： In a system for obtaining images on the principle of nuclear magnetic resonance (NMR) of nuclei contained in the human body, two symmetrical coils constituting an electromagnet are spaced apart so that a patient's body can be placed transversely with respect to the axis of revolution of the electromagnet. A set of NMR coils for producing a high-frequency magnetic field at right angles to the field of the electromagnet comprises at least one solenoid coil placed around the part of the body to be examined. This novel configuration achieves enhanced sensitivity and reduces exposure times by a factor greater than 2 with respect to conventional saddle-type NMR coil systems.

摘要： The magnet essentially comprises at least three pairs of coaxial coils in order to increase the number of available parameters, to reduce the non-uniformity B.sub.d, to provide an examination volume with a double access consisting of a longitudinal access along the axis of revolution Oz and of a transverse access parallel to the plane of symmetry, to minimize the overall size as well as the dissipated electric power. The nine principal characteristic parameters of the coils are chosen so as to optimize the uniformity of the magnetic field within the examination volume.
