Abstract

The invention discloses a Ki67 cell nucleus counting method and system based on pathological immunohistochemistry, and the method comprises the steps: placing a pathological section after Ki67 staining under an optical microscope, and collecting an image of the pathological section after Ki67 staining through visual detection equipment CCD; obtaining a Ki67 negative cell RGB image and a Ki67 positive cell RGB image; carrying out intercellular substance interference filtering on the RGB image to generate a binary image of Ki67 negative cells and a binary image of Ki67 positive cell RGB; carrying out element marking on the binary image, and calculating the number and indexes of connected regions of the binary image; calculating the area of each connected region, taking a standard cell connected region as a reference form, and filtering the connected region with the area smaller than the reference form; segmenting the adherent cells according to the standard that the area of the connectedregion is equal to twice of the reference form; marking Ki67 positive cells and Ki67 negative cells according to the index of the final connected region, and performing counting.

Description

technical field [0001] The present disclosure relates to the field of medical technology, in particular to a method and system for counting Ki67 cell nuclei based on pathological immunohistochemistry. Background technique [0002] The statements in this section merely mention background art related to the present disclosure and do not necessarily constitute prior art. [0003] Ki67 is a nuclear antigen (non-histone) that exists in each cycle of cell division. In pathology, immunohistochemical methods are usually used to mark its expression in the nucleus, so as to understand at a certain point in time. How many cells are in the stage of division and proliferation, and how many cells are in the quiescent stage, are a very meaningful indicator for judging the activity of tumor cells. Clinically, it is most commonly used in the histopathological diagnosis of breast cancer, neuroendocrine tumors, meningiomas, etc. It is of great value in judging benign and malignant tumors, rec...
