摘要： The present invention provides an ultrasonic imaging system capable of extracting structure-emphasized image data in which the structure of a tissue in a living body is emphasized and texture-emphasized image data in which a texture pattern coming from properties of a tissue in a living body is emphasized from B-mode image data, and obtaining a synthesized image obtained by weighting and combining the two extracted image data pieces. An ultrasonic imaging system has: a structure extractor for extracting structure-emphasized image data in which a structure of a tissue in the living body is emphasized from B-mode image data of the living body; a texture pattern extractor for extracting texture-emphasized image data in which a texture pattern coming from properties of a tissue in the living body is emphasized; an image synthesizer for obtaining a synthesized image by weighting and combining the structure-emphasized image data and the texture-emphasized image data; and a display for displaying at least one of the structure-emphasized image data, the texture-emphasized image data, and the synthesized image.

摘要： The invention provides an MRI apparatus capable of using a static magnetic filed magnet provided therein as a magnet for polarization, and performing DNP therein without changing a construction of a conventional MRI apparatus. A DNP means placed in the MRI apparatus includes a sample tube, cooling units for cooling and solidifying a sample in the sample tube, a microwave irradiating unit, and a metal tube. At least a member placed near an imaging space (five-gauss line) of the MRI apparatus is made of a nonmagnetic material, and a static magnetic field generating magnet of the MRI apparatus is used as a magnetic field applying means for applying a magnetic field to the sample for polarization. A contrast agent generated by the DNP can be immediately injected into a patient for imaging, so as to provide an image with high S/N.
