Breast mass segmentation method based on multi-modal feature fusion Vnet

Abstract

The invention provides a multi-modal feature fusion Vnet-based breast mass segmentation method. The method comprises the following steps: S1, obtaining a breast magnetic resonance image and a data set of breast mass segmentation results manually marked by a doctor; s2, data preprocessing: dividing data in the data set; s3, constructing a network model based on multi-modal feature fusion Vnet; s4, training the network model in the step S3, and performing parameter adjustment to obtain a predicted breast lump segmentation result; and S5, comparing the predicted breast lump segmentation result obtained in the step S4 with the breast lump segmentation result manually marked by the doctor in the step S1 by using a set evaluation index and a loss function, and verifying the effectiveness of the segmentation method. The breast mass segmentation accuracy can be effectively improved, doctors are assisted in diagnosis and decision making, the burden of the doctors is relieved, and the method has high application value in breast mass auxiliary diagnosis, operation simulation and medical teaching.

Description

technical field [0001] The invention relates to the field of medical image processing, in particular to a breast mass segmentation method based on multimodal feature fusion Vnet. Background technique [0002] Breast cancer is the most common malignancy in women and the leading cause of cancer death in women worldwide. Early screening and treatment are important means to improve the survival rate of breast cancer patients. Among them, magnetic resonance imaging technology has the characteristics of excellent soft tissue resolution and no radiation, and has unique advantages in breast examination. In recent years, more and more clinical and research work has been carried out on breast MRI in my country. Among high-risk patients with breast cancer, breast MRI has higher sensitivity. Although breast MRI is an important method for the examination and diagnosis of breast diseases, it is not easy for doctors to read MRI images. The doctor's judgment process is often time-consuming...

Problems solved by technology

Although breast magnetic resonance imaging is an important method for the examination and diagnosis of breast diseases, it is not easy for doctors to read MRI images. Heavy work, visual fatigue, which caused a decline in diagnostic accuracy

In the process of diagnosis, the human eye may not be able to distinguish the places with too small pixel contrast, resulting in the inability to accurately judge the small lesions, and it is easy to ignore the early lesions, which will affect the treatment.
