Abstract

The invention provides an automatic focusing scanning method and system based on the bone marrow cell glass slide. Automatic focusing scanning of a plurality of bone marrow smears is achieved, a digital image is formed, and remote reading of the same bone marrow smear can be achieved through a network. According to the automatic focusing scanning method for the bone marrow cell glass slide, the image definition is calculated in a specific image definition calculation mode and serves as an image feedback signal to adjust the position of a focus of bone marrow cell focusing imaging. The focusingprocess of bone marrow cell imaging is rapidly achieved, and the problem that the digitization speed and imaging definition of an existing scanning focusing system cannot be considered at the same time can be solved.

Description

technical field [0001] The invention relates to the technical field of medical pathological analysis, in particular to an automatic focus scanning method and system for bone marrow cell slides. Background technique [0002] In traditional pathological diagnosis, the pathologist observes the type and quantity of white blood cells in the bone marrow smear under the microscope with human eyes, and provides diagnostic basis for various types of leukemia. This is a very complicated, tedious, time-consuming task, and is easily affected by subjective factors. . With the rapid development of computer-aided methods and the update and iteration of related computing hardware, computer-aided diagnosis has become possible. The basis of computer-aided diagnosis is the digitization of bone marrow cell slides. The digitization process of bone marrow cell slides includes three steps: focusing, scanning, and mosaic imaging. The complexity of the focusing algorithm determines the speed of sca...
