In anatomy, a squamous epithelium is an epithelium whose most superficial layer consists of flat, scale-like cells called squamous epithelial cells. The epithelium may be composed of one layer of these cells, in which case it is referred to as simple squamous epithelium, or it may possess multiple layers, referred to then as stratified squamous epithelium. Squamous epithelial cells have a polygonal appearance when viewed from above.
An early esophageal cancer screening method and system based on artificial intelligence
The application relates to the field of artificial intelligence medical technology and discloses an early esophageal cancer screening method and system based on artificial intelligence, which comprises the following steps: preparing an obtained esophageal epithelial cell sample of a subject into a single-layer cytological smear, generating an original digital pathology image through optical scanning; extracting independent cells therefrom, calculating local spatial moment parameters of the independent cells; determining the geometric principal axis direction and stretching degree of the independent cells based on the local spatial moment parameters; judging whether the stretching degree exceeds the length-width ratio benchmark constant of normal esophageal squamous epithelial cells, if yes, applying a local two-dimensional affine transformation to the independent cells along the geometric principal axis direction to offset the mechanical stretching deformation caused by sampling, and generating calibrated cell image data; inputting the calibrated cell image data into an artificial intelligence classification module, extracting cell pathological features based on a deep convolutional neural network, and outputting a screening diagnosis result. The application offsets cell deformation interference and improves screening accuracy.
