    摘要: A magnetic resonance imaging system uses a first RF coil for acquiring a magnetic resonance signal from a subject, and a device for estimating a cardiac phase of the subject based on the magnetic resonance signal acquired by the first RF coil. The first RF coil, for example, can be an RF coil exclusive to cardiac phase estimation. The magnetic resonance imaging system also uses a second RF coil for acquiring a magnetic resonance signal based on the estimated cardiac phase, and a device for reconstructing a magnetic resonance image of the subject based on the magnetic resonance signal acquired by the second RF coil. Thus, MRA can be performed by estimating a cardiac phase.

    摘要: To optimize in advance a desired image quality determining pulse sequence parameter incorporated in an imaging scan, a preparation scan is adopted. The preparation scan is performed with the amount of at least one desired image quality parameter changed for each of plural preparatory images, so that a plurality of preparatory images at the desired same region of the object are acquired. For example, one such image quality parameter is TI (inversion time). The acquired preparatory scan data are processed into a plurality of preparatory images for display. A desired preparatory image is then selected from the plural preparatory images displayed, and the amount of the desired parameter used for that selected preparatory image is then set for use in the pulse sequence for a complete diagnostic imaging scan. Hence the desired image quality determining parameter of the pulse sequence is caused to have an optimum value before an actual complete diagnostic imaging scan.

    摘要: A magnetic resonance imaging apparatus comprises an imaging condition setting unit, a receiving unit, an image reconstructing unit, an image distortion correcting unit and an image correction estimating unit. The imaging condition setting unit sets mutually different image conditions. The receiving unit receives magnetic resonance signals from an imaging area according to the image conditions. The image reconstructing unit reconstructs a plurality of image data corresponding to the image conditions respectively based on the magnetic resonance signals. The image distortion correcting unit corrects distortions of the plurality of the image data based on a magnetic field distribution on the imaging area. The image correction estimating unit estimates whether a correction of at least one of the plurality of the image data is appropriate based on a plurality of corrected image data.

    摘要: Described in a joining agent for joining electrically ceramic bodies by heating the joining agent inserted at the parts to be jointed between the ceramic bodies with an electric current flowing predominantly through the joining agent at high temperature. The joining agent is superior in the wetability and reactivity with the ceramics to ensure the joint part strength. The joining agent includes, as an electric conductor, an electric conductive component made of an ion conductor consisting of fluoride, chloride, and/or oxide, which forms carrier ions by the pre-heating and has an electric conductivity higher than that of the ceramic body at the electric current supplying time. During the supplying electric current to time, the joining agent has the electric resistance increased gradually at the molten state of the joining agent by decreasing the density or the mobility of the carrier ions. After the electric heating, the joining agent is changed into a composition having a high electric resistance and hence the electric current path moves smoothly.

    摘要: A polishing pad thickness measuring method measures the thickness of a polishing pad attached to an upper surface of a surface plate. The polishing pad thickness measuring method measures a first distance between an upper surface of the polishing pad and a reference position on a vertical line perpendicular to the surface of the polishing pad and a second distance between an upper surface of the surface plate and the reference position on the vertical line, and calculates the thickness of the polishing pad from the difference between the first and second distances.
