Patent ID: 10481230

Abstract:
A shim system for influencing and homogenizing the magnetic field of an NMR system includes a coil former (1), an extension tube (2) and a terminal unit (3), as well as partial coils (4, 4a) that are mounted on the coil former. Terminal lines (6a, 6b) for connecting the partial coils to the terminal unit are initially electrically disconnected from one another between the coil former and the extension tube. A circuit board (5) with connection lines (5a, 5b, 5c, 5d), however, is interposed between the disconnected terminal lines. This makes it possible to redesign the shim system in the mechanical construction thereof using simple technical measures and standard components, and without giving rise to significant additional costs. Therefore, production of the partial windings on the coil former can take place in a simplified, economical and automated manner, without requiring an extension tube to be already fitted.
