Abstract: In the continuous moving table imaging, an image is reconstructed with suppressed artifacts even in imaging under inhomogeneity of static magnetic field. In a magnetic resonance imaging apparatus, signals are measured with moving a table to obtain multiple data sets, and inverse Fourier transform of each data set is carried out in the read-out direction to obtain hybrid data. One-dimensional data are extracted from each hybrid data at a border with respect to the adjacent hybrid data, and correction values for corrections of discontinuity of signal intensity and phase at a border of hybrid data are obtained by using the one-dimensional data. Data obtained by inverse Fourier transform of each hybrid data are corrected by using the correction values, and an image showing continuity for signal intensity and phase is eventually obtained.

Abstract: An electronic apparatus which makes it possible to reduce start-up time for starting the electronic apparatus, without necessitating installment of a plurality of CPUs in the electronic apparatus. A main CPU 45 controls a digital camera implementing the electronic apparatus. A storage medium for storing information can be detachably attached to a connector 97. A medium detection circuit 85 monitors a status of attachment and detachment of the storage medium to and from the digital camera, irrespective of a status of operation of the main CPU 45. The sensed status of attachment and detachment of the storage medium is stored in a register 115 of the medium detection circuit 85.

Abstract: A magnetic resonance measurement technique is provided which shortens the measurement time while suppressing artifacts caused by body movement of a measuring object and enables high-speed imaging. An excitation pulse which excites a plurality of slice planes and an excitation pulse which excites slice planes perpendicular to the slice planes are applied and a plurality of substantially parallel linear crossing areas are simultaneously measured. Spatial information of a linear direction of the crossing areas is acquired by modulating a magnetic resonance signal from the crossing areas by a gradient magnetic field. A spatial information of a direction perpendicular to the linear direction is acquired by changing the position of the plane and an image is reconstructed.

Abstract: When a magnetic resonance signal is received more than once, while a table (transfer unit) is moved, a gradient magnetic field is applied in the table moving direction, and an application amount (intensity and application time) of the gradient magnetic field in the table moving direction is changed every acquisition of data. As for the encoding by the gradient magnetic field in the table moving direction, a series of phase encode is performed at different positions of an examination target, unlike a conventional phase encode. Therefore, the Fourier transform cannot be applied to the image reconstruction. Given this situation, a magnetization map of total FOV of the examination target is determined in such a manner that a sum of the square of an absolute value of a difference is minimized, the difference between a received signal and a signal calculated from the magnetization map set as a variable, and then, the reconstruction is performed.
