Indication-Dependent Display of a Medical Image

The present invention relates to a medical data processing method of determining an image of an anatomical structure of a patient's body, the method comprising the following steps which are constituted to be executed by a computer: a) acquiring (S1) GP atlas data describing an image-based model of at least part of a human body comprising the anatomical structure; b) acquiring (S1) patient medical image data describing a patient-specific medical image of the anatomical structure in the patient's body, wherein the patient medical image data comprises in particular three-dimensional image information c) determining (S2), based on the atlas data and the patient medical image data, atlas-patient transformation data describing a transformation between the image-based model and the anatomical structure in the patient's body; d) acquiring (S3, S4) medical indication data describing a medical indication which the anatomical structure is subject to; e) acquiring (S7) imaging parameter data describing at least one imaging parameter for generating, from the image-based model, an image of the anatomical structure in dependence on the medical indication data: f) determining (S8) indication image data describing an indication-specific image (1) of the anatomical structure in the patient, wherein the indication image data is determined (S8) based on the patient medical image data and the atlas-patient transformation data and the medical indication data and the imaging parameter data.

Method and system for detecting macroscopic mura defects on large-size liquid crystal panel

The invention discloses a method for detecting macroscopic mura defects on a large-size liquid crystal display panel. The method comprises the following steps of collecting a plurality of frame imagesof different areas on a liquid crystal display panel to be detected according to a preset frequency and a relative motion path, splicing all the collected frame images into a complete panorama according to the physical coordinates of the frame images, iteratively compressing the complete panorama for multiple times by using an image compression algorithm to obtain a compressed image of the liquidcrystal display panel to be detected, carrying out compensation processing on the compressed image of the to-be-detected liquid crystal display panel to obtain a preprocessed image of the to-be-detected liquid crystal display panel, carrying out the contrast enhancement processing on the preprocessed image of the liquid crystal panel to be detected by using a contrast-limited adaptive histogram equalization algorithm, and carrying out binary morphological processing on the enhanced pre-processed image to obtain an adaptive binary image, the adaptive binary image comprising a plurality of spots used for representing the macroscopic mura defect information, and obtaining the macroscopic mura defect information according to the spots.
