Method for producing a longitudinal magnetic field gradient of high uniformity within the test object and an arrangement for its implementation

摘要

the subject of the invention is a manufacturing podluznych gradients magnetic fields on the object and a jednorodnosci arrangement for its implementation,with application in ct, mri magnetic.process for the production of podluznych gradients magnetic fields a jednorodnosci on the test object is,with is used two pairs of coils (1) and (1 ') and (2) and (2') in which coil (1) and (2) the current flows in the same direction, while in the coil (1) and (2) the current flows in the same direction.but in the opposite direction to the coils (1) and (2).arrangement for manufacturing podluznego gradient magnetic fields on a jednorodnosci test facility, has thethere are two pairs of coils (1) and (1 ') and (2) and (2') of the preferably equal, situated wspu00f3losiowo fitted permanently, rozlacznie ct scan to the housing.for which the current in the coil (1) and (2) flows in the same direction, while in the coil (1) and (2) the current flows in the same direction, but in the opposite direction to the coils (1) and (2).
