  • Publication number: 20090005545
    Abstract: One aspect of the present invention relates to a method of purifying radiolabelled compounds comprising a) loading onto a fluorous polymer a radiolabelled compound precursor comprising a fluoroalkyl tin moiety; b) reacting the radiolabelled compound precursor with a radiolabel delivering compound to give a radiolabelled compound, wherein the fluoroalkyl tin moiety is replaced by a radiolabel; and c) eluting the radiolabelled compound from the fluorous polymer.

  • Publication number: 20050129610
    Abstract: The present invention relates to radiolabelled compounds particularly 1-azabicyclo[2.2.2]octane compounds (i.e., quinuclidine compounds) which are labeled with one or more radioisotopes and which are suitable for imaging or therapeutic treatment of tissues, organs, or tumors which express the a7-nicotinic cholinergic receptor. In another embodiment, the invention relates to methods of imaging tissues, organs, or tumors using radiolabeled compounds of the invention, particularly tissues, organs, or tumors which express a7-nicotinic cholinergic receptor to which the compounds of the invention have an affinity.

  • Patent number: 5751845
    Abstract: Method for generating harmonic color corrections in a color image. The color image is deposited in an image store and is displayed on a monitor. Color samples of the colors that are to be subjected to a selective color correction are taken from the image with a coordinate input means. Color correction values that act on the colors defined by the color samples are input. In order to obtain harmonic transitions at the locations in the image where the selected colors meet non-selected, neighboring colors, the color correction decreases toward the edges of the color correction area. This is achieved by a filtering of the color samples or color correction values. A color computer calculates the corresponding color correction values.

  • Patent number: 5489921
    Abstract: A method for selective color correction of a color image that is deposited in a store and is displayed on a monitor. Color samples of the colors that are to be corrected are taken from the image with a coordinate input means. The color samples are deposited in a color sample memory and form a cloud in a CIELAB color space. This cloud usually has gaps and singular dots. In order to avoid discontinuities, the cloud is filtered and the gaps and singular dots are thus removed. The arrangement of the color samples in the color space can be displayed in a dialogue window in that color correction values are also input. A color computer uses the color samples and the color correction values for the selective color correction of the image. The image corrected in this way can be stored in the store and can be used for the production of color separations.
