Claims

[Scope of utility model registration request]

(1) A subject is placed in a uniform static magnetic field generated by a static magnetic field generating coil, and a gradient magnetic field is superimposed on this uniform static magnetic field and an excitation rotating magnetic field is applied to generate a planned tomographic section of the subject. A nuclear magnetic resonance phenomenon is generated in the target tomographic plane, a nuclear magnetic resonance signal induced by a probe head placed surrounding the intended tomographic plane is detected, projection information of the intended tomographic plane of the subject is obtained, and an image is generated. In the nuclear magnetic resonance imaging apparatus that obtains image information reflecting at least one of the spin density distribution and relaxation time constant distribution of a specific atomic nucleus in the cross-sectional plane of the object by performing reconstruction processing, the probe head What is claimed is: 1. A nuclear magnetic resonance imaging device characterized by being configured to be openable and closable.

(2) The nuclear magnetic resonance imaging apparatus according to claim (1) of the utility model registration claim, wherein the opening/closing part of the probe head is made of a flexible and highly conductive material and is connected to a receiving coil. .
