Abstract

PURPOSE:To miniaturize a high frequency coil while keeping a necessary uniform space, by selecting the coordinates of each turn coil composed of two up-and-down symmetric saddle-shaped coils to the coordinates value in the vicinity of the specific optimum coordinates value. CONSTITUTION:This high frequency coil is constituted of at least two turn coils 1, 2 composed of two saddle-shaped coils 11, 12 and 21, 22 and the saddle-shaped coils 11, 12, 21, 22 are respectively symmetric with respect to an xy-plane and a yz-plane and a linear part is composed of two conductors parallel to a z-axis and two saddle- shaped coils 11, 12 constituting one turn coil 1 are symmetric with respect to a zx-plane containing the z-axis and an x-axis. When the number of the turn coils are set to N and the coordinates value of the conductor wherein the position of the xy-plane is present in the first quadrant among the conductors of four linear parts constituting the n-th turn coils is set to xln, yln, xln, yln of each turn coil, wherein all of the coefficients of the items of degrees from 1 to 4N-1 among the coefficients of respective degrees when the distribution of the flux density generated by the high frequency oils on a y-axis is expanded in a power series of the width of y become 0, are set to the optimum coordinates value and the coordinates value of the conductor of each turn coil is set to the value within the range containing said optimum coordinates value.
