Abstract

The present invention claims a detection method based on abdominal CT medical image fusion classification. The detection method comprises: an acquisition step of acquiring an abdominal CT scanning image of a patient; a pre-processing step of performing pre-processing to obtain a binarized grayscale image; a morphological corrosion and dilation step of performing morphological corrosion calculationto obtain a corroded image, and performing dilation operation on the binarized grayscale image to obtain a dilated image; an operation step of performing opening operation on the corroded image to obtain an open operation map and performing closed operation on the dilated image to obtain a closed operation map; a Fourier transform step of obtaining a Fourier transform value; an abdominal medicalimage fusion classification step for performing fusion classification distinguishing on the abdominal CT scanning image; and a lesion detection step of performing determination according to the Fourier transform value and the fusion classification distinguishing result to obtain a suspected lesion area of the patient. The invention can lower the complexity and improve the accuracy of recognition and diagnosis of abdominal lesions.

Description

technical field [0001] The invention belongs to the technical field of medical image processing, in particular to a detection method based on abdominal CT medical image fusion classification. Background technique [0002] The existing abdominal medical image fusion technology is mainly for two different modal medical images. According to the different medical image modalities, the medical image fusion system can be divided into three types: anatomical medical image and anatomical medical image fusion, anatomical medical image and anatomical medical image fusion. Functional medical image fusion and functional medical image and functional medical image fusion. The MRI-PET and MRI-SPECT medical image fusion system belongs to the fusion of anatomical medical images and functional medical images. The input images of this system are grayscale and pseudo-color. The MRI-PET combination kit launched by Philips combines a commercial MRI imaging scanner with a PET with special shieldi...
