A lens array is arranged in front of the screen of an image display at a distance of S1. The lens array consists of lenses having focal lengths f1 and f2. The focal length f1 and f2 and the distance S1 determine the forming positions of first and second imaging planes. The first imaging plane is formed at a position of distance S3 from the lens array and the second imaging plane is formed at a position of distance S2. More specifically, a pixel on the screen is imaged as a first imaging element of the first imaging plane at a position of S1+S3 form the screen and a pixel on the screen is imaged as a second imaging element of the second imaging plane at a position S1+S2 from the screen. A viewer can attain stereoscopic feeling when viewing them.

A recording apparatus records information onto a recording medium. The recording apparatus is provided with: a near-field light device; and a control unit for controlling the near-field light device. The near-field light device is provided with: a light source; a quantum dot structure which is laminated on the light source; a plurality of quantity dots which are included in the quantity dot structure and each of which generates near-field light on the basis of light emitted from the light source; and an output end which is configured to output at least one portion of energy of the near-field light to the exterior of the quantity dot structure. The control unit of the recording apparatus controls the light source to emit the light upon recording the information, thereby increasing temperature of a region of the recording medium based on a size of the output end.

A magnetic resonance imaging (MRI) system obtains an MR image of an object. The system detects an ECG signal and performs a pulse sequence of RF gradient magnetic fields toward the object. Imaging defined by the pulse sequence is longer in temporal length than one heartbeat. The system further acquires an MR signal from the object in response to performance of the pulse sequence and produces the MR image based on the acquired MR signal. Also possible are: a plurality of divided MT pulses instead of the conventional single MT pulse, an SE-system pulse sequence having a shorter echo train spacing, and the generation of sounds by applying gradient pulses incorporated in an imaging pulse sequence so as to automatically instruct a patient to perform an intermittent breath hold.

A storage unit stores a parameter list that defines a method of creating scanning conditions for a preparation scan from scanning conditions set for a main scan, with respect to each type of scanning. A scanning-condition edit/scan positioning unit receives an operation of selecting a type of a preparation scan, and when the operation of selecting the type of the preparation scan is received, the scanning-parameter limit calculating unit acquires the parameter list corresponding to the type of the preparation scan, from among the parameter lists stored by the storage unit, creates scanning conditions for the preparation scan from scanning conditions set for a main scan based on the parameter list corresponding to the type of the preparation scan. The pulse-sequence execution-data creating unit then causes execution of the preparation scan based on the created scanning conditions.

A magnetic resonance imaging apparatus includes an RF coil unit which generates RF pulses toward a subject, and which receives an MR signal from the subject. Gradient magnetic field coils generate a gradient magnetic field for slice selection, a gradient magnetic field for phase encoding and a gradient magnetic field for frequency encoding, respectively. An arithmetic unit generates image data on the basis of the MR signal, and a sequence controller controls phase encoding gradient magnetic field coils in order to generate flow pulses for dephasing or rephasing the MR spin of blood flow within the subject, in the same direction as that of the phase encoding gradient magnetic field.
摘要:
Image reconstruction is executed by using magnetic resonance signals obtained by asynchronous multi-slice dynamic imaging without using any ECG-gated technique to obtain a plurality of MR images for each time phase with respect to a plurality of cross-sections corresponding to sequential changes in radio-frequency pulse frequency. The heart of a subject to be examined in MR images in the same time phase is developed by being divided into a plurality of small regions, and a developed view representing the average value of pixel values in each of the small regions is generated. For example, the developed views in the respective time phases are continuously displayed in a time-series manner.

A meter has a liquid crystal display panel. The liquid crystal display panel is adapted to display a dial picture image thereon. A backlight illuminates the liquid crystal display panel. A movement is located in front of a front surface of the liquid crystal display panel. A semi-translucent panel covers the front surface of the liquid crystal display panel. A pointer is pivotably supported by the movement in such a manner that the semi-translucent panel is located between a pivotal trajectory plane of the pointer and the liquid crystal display panel. The semi-translucent panel enhances a contrast between the dial picture image and a background image displayed on the liquid crystal display panel.
