Design of a high-resolution segmentation network for digital subtraction angiography of cerebral vessels
To solve the problem of low accuracy of existing convolutional neural networks for cerebral vascular DSA image segmentation
an improved network based on U-Net (IC-Net) is proposed. By fusing the use of inception and channel attention modules
rich vascular feature information is extracted using multiple sensory domains and feature information is filtered. A new 7×7 convolutional layer is added to reduce the amount of data generated during training by compressing the feature layer resolution. Compared with the U-Net and common U-Net improved models
the improved model's intersection over union
accuracy
F1-score
and area under the curve increase by 1.82 %
0.014 %
1.19 %
and 0.73 % on average
respectively. The results verify that the IC-Net model remarkably improves the model's capabilities to detect weak vessels and vessel ends in cerebrovascular digital subtraction angiography images and distinguish artifactual noise. The model provides a strong reference for physicians to identify lesions within cerebrovascular vessels.
