A system and method for automatic film change of digital pathological slides

Abstract

A system and method for automatically changing slides of digital pathological slices, placing the pathological slides in a storage rack, marking the placement position of the pathological slices on the storage rack as the initial grabbing position, obtaining the placement position of the pathological slide scanner and marking is the initial scanning position; determine the first spatial trajectory of the robotic arm transferred to the initial grasping position according to the starting position of the robotic arm; the robotic arm is transferred to the initial grasping position according to the first spatial trajectory to grasp the pathological slice; According to the initial grasping position and the initial scanning position, determine the second space movement trajectory of the mechanical arm transferred between the storage rack and the pathological slice scanner; transfer to the initial scanning position according to the second space movement trajectory to scan the pathological slice; the scanning is completed The pathological slices are transferred from the initial scanning position to the initial grasping position, and the scanning status of the pathological slices at the initial grasping position is marked. The invention has low cost, does not need special personnel to be on duty, and improves work efficiency.

Description

technical field [0001] The invention relates to the technical field of slice processing, in particular to an automatic slice change system and method for digital pathological slices. Background technique [0002] Pathological sections are usually embedded in paraffin blocks, cut into thin slices with a microtome, and then stained with hematoxylin-eosin (H-E). The digital pathological slice scanner can automatically scan pathological slices and generate full-width digital images of pathological slices, which is convenient for pathologists to view pathological images on a computer, and can support remote diagnosis and automatic image processing and analysis based on artificial intelligence. [0003] At present, high-end pathological slide scanners are all designed with built-in automatic slice changing device to realize the automation of scanning, but the mechanical structure is complicated, the scanner is bulky and the price is expensive. When the scanning volume is large an...
