  • Method and device for producing thin sections of a sample by means of an image recognition system
    Patent number: 8687858
    Abstract: A method and a device for producing thin sections of a sample by means of a microtome is described, in which a camera acquires at least one image of a surface generated by sectioning of the sample. With the aid of an evaluation device, the image of the surface is evaluated in terms of predefined characteristic values of a section quality. As a function of the characteristic values that are identified, a decision is then made as to whether the section of the sample is accepted or not.
    Type: Grant

  • METHOD AND APPARATUS FOR OPERATING A MICROTOME
    Publication number: 20100101385
    Abstract: A method and apparatus for operating a microtome are described. According to the method, a specific type of a sample to be sectioned is detected, at least one stored sectioning parameter value is determined as a function of the specific type of the sample that was detected, said value being allocated to the specific type of the sample and defines a specific setting of the microtome, and the setting the microtome as defined by the determined sectioning parameter value is performed automatically.
