Abstract
Przedmiotem wynalazku jest sposób wytwarzania podluznych gradientów pól magnetycznych o duzej jednorodnosci w obrebie badanego obiektu i uklad do jego realizacji, majacy zastosowanie w tomografii rezonansów magnetycznych. Sposób wytwarzania podluznych gradientów pól magnetycznych o duzej jednorodnosci w obrebie badanego obiektu polega na tym, ze stosuje sie dwie pary cewek (1) i (1') oraz (2) i (2') przy czym w cewkach (1) i (2) prad plynie w tym samym kierunku, natomiast w cewkach (1') i (2') prad plynie w tym samym kierunku, ale w przeciwnym kierunku wzgledem cewek (1) i (2). Uklad do wytwarzania podluznego gradientu pól magnetycznych o duzej jednorodnosci w obrebie badanego obiektu, charakteryzuje sie tym, ze sklada sie z dwóch par cewek (1) i (1') oraz (2) i (2') o promieniach korzystnie jednakowych, usytuowanych wspólosiowo, zamocowanych trwale, rozlacznie do obudowy tomografu, dla których prad w cewkach (1) i (2) plynie w tym samym kierunku, natomiast w cewkach (1') i (2') prad plynie w tym samym kierunku, ale w przeciwnym kierunku wzgledem cewek (1) i (2).The subject of the invention is a method of producing longitudinal magnetic field gradients with high homogeneity within the examined object and a system for its implementation, applicable in magnetic resonance tomography. The method of producing longitudinal magnetic field gradients with high homogeneity within the examined object consists in the fact that two pairs of coils (1) and (1 ') as well as (2) and (2') are used, with coils (1) and (2) ) the current flows in the same direction, while in the coils (1 ') and (2') the current flows in the same direction, but in the opposite direction relative to the coils (1) and (2). The system for producing a longitudinal gradient of magnetic fields with high homogeneity within the examined object is characterized by the fact that it consists of two pairs of coils (1) and (1 ') as well as (2) and (2') with preferably uniformly aligned radii , permanently attached, detachably to the tomograph housing, for which the current in the coils (1) and (2) flows in the same direction, while in the coils (1 ') and (2') the current flows in the same direction, but in the opposite direction relative to coils (1) and (2).
