摘要： In a magnetic resonance imaging apparatus according to an embodiment, an array coil is structured by arranging a plurality of coil elements each of which receives a magnetic resonance signal generated from a subject. An acquisition controlling unit acquires the magnetic resonance signals while changing a position to be selected and excited within the subject who has the array coil attached thereon. A large-area image generating unit generates a large-area image of the subject, based on the magnetic resonance signals acquired by the acquisition controlling unit. A position measuring unit measures positions of the coil elements, based on strengths of the magnetic resonance signals used for generating the large-area image and positions of the couchtop corresponding to the times when the magnetic resonance signals were acquired.

摘要： A system for accurately measuring the direction in which a magnetometer is to be set has a simple construction and is little affected by iron structures on a hull. The system has a magnetometer which includes an excitation source, a magnetic core, an excitation AC winding and an output winding which are both wound around the magnetic core. The output winding is composed of two series connected coils which are wound around the magnetic core and have an equal number of turns. The measuring system applies an alternating current to the core having an amplitude large enough to saturate the magnetic core, and obtains an output from the output winding corresponding to the angle formed between the geomagnetic field direction and an imaginary line obtained by interconnecting the point of connection of the two coils and the central point of the magnetic core.

摘要： The invention is intended to reduce the weight of the entire unit, make it compact and prevent the emitted light from being in dark and bright stripes in a light guide unit for a back light of a liquid crystal display device. Further, this invention allows a prism sheet having a larger apex angle to be used. To this end, the light guide unit comprises a plurality of light guide films laminated on the light guide member. The sloped surface which is opposite to the incident surface of the light guide unit is formed with grooves each having an inclination of an angle related to Brewster angle. A prism sheet is further disposed with the side having apexes oriented to the light guide unit to deflect the light emitted from the light guide unit.
