GRADIENT-GENERATION SYSTEM, NUCLEAR-SPIN TOMOGRAPH AND PROCESS FOR THE GENERATION OF IMAGES USING A NUCLEAR-SPIN TOMOGRAPH

摘要

Device for the production of magnetic field gradients that are superimposed temporarily to the static magnetic field of a nuclear spin tomograph, with at least one pair of gradient coils powered by a power supply box, in series operation, are traversed by a current and produce, in a predetermined scanning volume, a magnetic field gradient varies linearly in a direction at least approximately with the location, characterized in that each gradient coil (a, B) has a game comprising at least a first winding section (S1) and a set comprising at least a second winding section (S2) which have separate connections to each other (16, 17; 18, 19), of so that the winding sections are easily connectable to each other and separated from each other in different ways. The user can also change the properties of gradient device.
