  • Publication number: 20100081917
    Abstract: A cardiac functional analysis system reconstructs a 3D anatomical image volume using image frames acquired at predetermined cardiac phases over multiple cardiac cycles in response to a trigger derived from hemodynamic signals. A medical imaging system generates 3D anatomical imaging volume datasets from acquired 2D anatomical images. The system includes an image acquisition device for acquiring 2D anatomical images of a portion of patient anatomy in selectable angularly variable imaging planes in response to a synchronization signal derived from a patient blood flow related parameter. A synchronization processor provides the synchronization signal derived from the patient blood flow related parameter. An image processor processes 2D images acquired by the image acquisition device of the portion of patient anatomy in multiple different imaging planes having relative angular separation, to provide a 3D image reconstruction of the portion of patient anatomy.

  • Publication number: 20090240083
    Abstract: This invention is involved with a preparation method of 2,6-dichlor-4-trifluoromethyl aniline. With this process, 4-chlorotrifluoromethyl benzene is used as the starting material and subjected to halogenation reaction and ammoniation reaction and through separation of reaction products the desired 2,6-dichlor-4-trifluoromethyl aniline is obtained. In addition, ammonia is recovered from the surplus ammonia water in ammoniation reaction. This applied invention in characterized by simple process, cheap and easy-available raw materials, high reaction yield and friendly environment.

  • Publication number: 20090197308
    Abstract: A method of sulfating a polysaccharide is provided. The method can include providing a reaction mixture comprising at least one O-sulfotransferase (OST) enzyme and 3?-phosphoadenosine 5?-phosphosulfate (PAPS); incubating a polysaccharide substrate with the reaction mixture, wherein production of the sulfated polysaccharide from the polysaccharide substrate is catalyzed by the OST enzyme with a conversion of the PAPS to adenosine 3?,5?-diphosphate (PAP); and providing a reaction condition which modifies PAP to reduce an inhibitory effect of PAP on the polysaccharide sulfation.
