  • Publication number: 20120027282
    Abstract: An ultrasonic diagnostic apparatus is provided for displaying a color map on which a difference in blood flow dynamics is reflected. Setting a test subject who is administered a contrast agent is assumed as an imaging target, and a probe transmits and receives ultrasonic waves to and from the target for contrast imaging. Image data is constructed based on signals received by the probe and a time-intensity curve is generated from intensity values of the image data. According to the time-intensity curve, a value of a predetermined parameter is calculated for producing a distribution image of blood flow dynamics. The distribution image (color map) of the blood flow dynamics is produced from the parameter value. The color map is a two-dimensional or a three-dimensional image being color-coded according to the parameter value.

  • Publication number: 20110222646
    Abstract: An X-ray imaging apparatus includes an X-ray generation part, an X-ray detection part, and a revolution drive mechanism. The X-ray generation part has an X-ray generator including a cathode and an anode, and emits an X-ray beam from the X-ray generator. The X-ray detection part detects the X-ray beam. The revolution drive mechanism performs X-ray imaging by revolving the X-ray generation part and the X-ray detection part around the object while the X-ray generation part and the X-ray detection part are opposed to each other with said object interposed therebetween. The X-ray imaging apparatus controls a restriction part to thereby restrict an X-ray transmission in such a manner that the focal spot size of an X-ray beam used in X-ray CT imaging of a relatively narrow imaging region is smaller than the focal spot size of an X-ray beam used in X-ray CT imaging of a relatively large imaging region.

  • Patent number: 7595301
    Abstract: Conventional oligonucleotides are opened at both ends and thereby unstable. Their stability against catabolic enzymes is increased by phosphorothioate modification, but such phosphorothioate causes toxicity. The present invention provides oligonucleotides and medicaments in which these problems are improved. That is, it provides staple oligonucleotides and medicaments containing the same as the active ingredient. Specifically, it provides transcription factor inhibitors, antisense oligonucleotides and siRNAs. More specifically, it provides agents for preventing, treating or improving inflammation, autoimmune diseases, central diseases, reperfusion injury in ischaemic diseases, worsened prognosis after organ transplantation or organ surgery, or restenosis after PTCA.
