摘要： PROBLEM TO BE SOLVED: To provide a magnetic resonance measurement technique capable of high speed imaging by shortening measurement time, while suppressing artifacts caused by body movement of a measuring object. SOLUTION: An excitation pulse for exciting a plurality of slice planes and an excitation pulse for exciting slice planes perpendicular to its slice planes are impressed, and a plurality of substantially parallel linear crossing areas are simultaneously measured. Spatial information of the linear direction of the crossing area is acquired by modulation by a gradient magnetic field. A spatial information of the direction perpendicular to the linear direction is acquired by changing a position of a plane, and an image is reconstructed. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an NMR probe coil with improved sensitivity of a superconducting solenoid coil.
SOLUTION: A superconducting solenoid coil and a superconducting one-turn coil are resonated at a frequency higher than a frequency actually used singly, respectively. The one-turn coils 51-1, 51-4 are arranged in the axial direction of the solenoid coils 51-2, 51-3 so that their superconducting thin film surfaces become parallel. The superconducting one-turn coils are not electrically connected to the solenoid coils and are isolated from power supply. The capacitance of the capacitors loaded on the coils is adjusted so that a peak with a lower frequency out of two resonance peaks appearing in the frequency characteristics of input impedance coincides with the frequency actually used.

摘要： PURPOSE: To provide an MRI image pickup method capable of obtaining high resolution images in different magnetic relaxation conditions in a short time by obtaining a part of a respective image divided by measurement spaces during a relaxation process and repeating it to obtain the whole signals necessary for making n sheets of images. CONSTITUTION: After applying 180 deg. RF pulses from a transmission coil 109, a dephase gradient magnetic field is applied onto a testee. Then, θ deg. RF pulses and a slice selection gradient magnetic field are simultaneously applied to determine the notice slice of the testee and magnetization of atomic nuclei in the slice is leaned by θ deg.. Following that, a rephase gradient magnetic field and a dephase gradient magnetic field are applied as well as an encode gradient magnetic field and a lead out gradient magnetic field. Echo signals relating to n sheets of images in different relaxation conditions are obtained by repeating those steps orderly n times (procedure A). Next, the whole echo signals necessary for making n sheets of image are obtained by repeating the procedure A 4 times by changing the sizes of dephase gradient magnetic fields.
