    摘要: A method for correcting the image data representing the blood flow for the evaluation and quantitative representation of the blood flow in a tissue or vascular region is based on the signal of a contrast agent injected into the blood. Several individual images of the signal emitted by the tissue or vascular region are recorded and stored at successive points in time. At least two individual images are correlated and a shift vector is generated based on the correlation. Thereafter, the image data of the individual images are shifted in relation to each other according to the shift vector.

    摘要: A method for the quantitative representation of the blood flow in a tissue or vascular region is based on the signal of a contrast agent injected into the blood. In the method, several individual images of the signal emitted by the tissue or vascular region are recorded at successive points in time and are stored. Based on the respective signal, a quantity characteristic for the blood flow and a quantity characteristic for the position of the blood vessels are determined for image areas of individual images. These quantities are represented superimposed for the respective image areas such that both the blood flow quantity and the position of the fine blood vessels become clearly visible in the representation and can be differentiated from the tissue.

    摘要: The invention relates to an image-processing method for automated contrast modification of digital image data. At least one low and one high-frequency signal are formed based on the digital image signal of the image data; the low-frequency signal component is modified using a characteristic-curve function; and then the modified, low-frequency signal is again added to the high-frequency signal component. In order to prevent the occurrence of distracting artifacts, so-called “halos”, the formation of the low-frequency signal component to be modified is formed in dependence upon the high-frequency image components.

    摘要: A method determines the position and/or radius of the limbus and/or the position and/or radius of the pupil of a patient eye. In the method, an image of the patient eye is obtained and a plurality of different ring-shaped comparison objects having respective radii and respective centers are provided. The image is correlated with the plurality of comparison objects to yield a local best match between the image and the comparison objects when there is a coincidence of one of the ring-shaped comparison objects and a ring-shaped jump in brightness in the image having the same radius and the same center. The comparison objects having a local best match with the image are determined. Thereafter, the position of the center of the comparison object having a local best match with the image is selected as the position of the center of the limbus and/or the position of the center of the pupil.
