Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0026] Such as Figure 1~2 As shown, the automatic segmentation method of the panoramic scanning pathological image transfer area provided by the present invention comprises the following steps:

[0027] Step 1: Preprocessing the panoramic scanning pathological image to extract organized regions, the specific method is as follows:

[0028] In order to reduce the calculation time and avoid excessive calculations in a large number of white background areas, the panoramic scanning pathological images are firstly used in low-resolution Ostu threshold method to exclude background areas;

[0029] Then the organized area under the low magnification corresponding to the target area under the full scan...

Abstract

The invention discloses a method for automatically segmenting the transfer region of a panoramic scanning pathology image. The method herein includes the following steps: pre-processing a panoramic scanning pathology image, extracting regions with tissues; acquiring a training sample set, marking a transfer part and a non-transfer part; constructing a deep convolutional network model and training the model, using the well trained deep convolutional network model to identify the transfer regions and non-transfer regions in the panoramic scanning pathology image; and representing the panoramic scanning pathology image by a heat value graph. According to the invention, the method herein can provide quantitative diagnosis information to a doctor, reduces errors that are caused by the doctor's subjective experience in observing slice images, can shorten time awaiting the diagnosis, and provides precious therapy time for patients.

Description

technical field [0001] The invention relates to an automatic segmentation method of a panorama scanning pathological image transfer area, which belongs to the technical field of medical image processing. Background technique [0002] Breast cancer is one of the main malignant tumors that endanger women's health, and it is also one of the malignant tumors with a rapid increase in incidence in my country in recent years. The traditional detection method of breast cancer metastasis mainly relies on the diagnosis of histopathological sections by pathologists, which not only has a large workload, but also has great inconsistency in the evaluation criteria of each doctor. Due to the substantial improvement in the storage performance and computing performance of computers in recent years, diagnosis with the help of computers has gradually become popular. However, there is still little research on image processing technology in our country, so it is very important to study a set of...
