Abstract:
1. A magnetic resonance imaging apparatus having a table-top for resting a subject thereon, a table-top drive mechanism for moving the table-top in a lengthwise direction (z-axis direction), and a computer for controlling a movement rate of the table-top by providing a control signal to the table-top drive mechanism, so that a 2D real-time monitor image is produced during a continuous table-top movement 3D imaging process, the apparatus comprising: a table-top movement-rate control unit configured to control the table-top drive mechanism to move the table-top; a data collecting unit configured to collect raw 3D data in kx, ky, and kz space provided by a nuclear magnetic resonance signal while moving the table-top where x and y coordinate axes are orthogonal to said z-axis; a 2D-image acquiring unit configured to acquire a 2D monitor image based upon raw 2D data forming a part of the raw collected 3D data, concurrently with collection of the raw 3D data; and a display control unit configured to control display of the 2D monitor image, concurrently with ongoing collection of the raw 3D data; wherein the 2D-image acquiring unit has
