A menu display device includes: means for displaying on a screen a given range within a menu, in which a plurality of menu items are arranged in an array; means for moving the given range in response to a predetermined operation performed by a user; means for determining whether or not the menu item at an end within the menu is displayed in a predetermined position of the screen; and means for changing, when the menu item at the end is displayed in the predetermined position of the screen, the space between the menu items displayed on the screen in response to the predetermined operation performed by the user.
Abstract:
In order to prevent quenching caused accidentally in a superconducting magnet, an MRI apparatus vibrates the superconducting magnet in order to prevent quenching of the superconducting magnet in a time period for which a predetermined imaging sequence is not executed (step 210). As a specific method, a gradient magnetic field may be generated by a gradient magnetic field coil for an imaging sequence of the MRI apparatus, or a gradient magnetic field may be generated using a gradient magnetic field coil for vibration provided apart from the gradient magnetic field coil for an imaging sequence. In addition, in a period for which the predetermined imaging sequence is not executed, a phantom may be imaged to prevent the quenching of the superconducting magnet.

An exemplary information-processing device includes: a first display controller configured to display selectively on a display a first image and a second image including the first image in a reduced size; and a second display controller configured, while the second display is displayed on the display, to display an indicator image on the display, the indicator image indicating a position of an image to be displayed when display of the second image is changed to display of the first image.
Abstract:
A magnetic resonance imaging apparatus includes: a pair of static magnetic field generators separately disposed at the top and bottom of an imaging space in which a subject is placed; a shim magnetic material, disposed on the imaging-space side of each of the pair of static magnetic field generators, for generating a magnetic field to adjust the static magnetic field; a gradient magnetic field generator; a high-frequency magnetic field generator; a temperature sensor for directly or indirectly measuring the temperature of the shim magnetic material; and a controller for controlling the gradient magnetic field generator and the high-frequency magnetic field generator to execute an imaging pulse sequence. The controller determines the inhomogeneity of the static magnetic field from the output of the temperature sensor, considering the change in a magnetic field adjustment parameter due to the temperature change of the shim magnetic material, and causes a warning message to be presented if the determined static magnetic field inhomogeneity has exceeded a predetermined allowable value.
Abstract:
An exemplary information-processing device includes: a display controller configured, when a second application program, capable of performing a search is activated during execution of a first application program, to display a second image displayed as a result of execution of the activated second application program, and a first image that has been displayed as a result of execution of the first application program before activation of the second application program; and an execution controller configured to notify the second application program of an event corresponding to an input operation, to execute a process according to a procedure described in the second application program, while maintaining the first image to be displayed.
Abstract:
An example information-processing device includes: am acquisition unit configured to acquire application-related information relating to a first application program; and a presentation unit configured, when a second application program, by which a search can be performed, is activated after activation of the first application program, to present to a user the application-related information acquired by the acquisition unit as a candidate for an item to be searched for.

Abstract:
Provided is an open-type MRI apparatus comprising a pair of magnetic field generating means arranged to face each other across a space for imaging an object, a pair of static magnetic field generating means holding means for holding the pair of static magnetic field generating means at a predetermined interval, and a pair of tabular gradient magnetic coil structures arranged on the imaging space side of the static magnetic field generating means. The individual tabular gradient magnetic coil structures are fixed on their individually facing static magnetic field generating means at a plurality of positions for suppressing the deformations, which occur in the gradient magnetic coil structures, by the Lorentz forces which act, when driving electric currents are fed to gradient magnetic coils, on the coil conductors.
Abstract:
To provide an image display control device capable of displaying a process for switching images in a manner readily recognizable by an observer when sequentially displaying a plurality of images on a display device. An image display control device displays a first image at a predetermined position in a predetermined display area, then repetitively carries out a process for producing and displaying a first transitional image in which the first image is displayed at a first display position in the display area, with brightness lowered for at least a partial area in the display area, while moving the first display position in a direction going away from the predetermined position, then repetitively carries out a process for producing and displaying a second transitional image in which a second image is displayed at a second display position in the display area, with the brightness lowered for at least the partial area in the display area, while moving the second display position in a direction approaching the predetermined position, and thereafter displays the second image at the predetermined position.
