Abstract
An adjustable signal coil, for example a solenoid, saddle or Helmholz type of signal coil which is used in a nuclear spin or NMR examination assembly, includes a pair of adjustable conductor guide and profile supports which hold one or more turns of a conductor forming the signal coil. The coil volume is changed by adjusting the supports to correspond to different sizes of targets to be positioned and examined inside the coil. In a disclosed embodiment, the coil volume is cylindrical and has its diameter changed by adjusting the spacing between the pair of supports, and the coil turn length and size, are adjusted by sliding guides within guideways of the supports.
