Abstract
A recognition method of intracranial vascular lesions based on transfer learning is provided, which includes: obtaining a bright-blood image group, a black-blood image group and an enhanced black-blood image group; registering bright-blood images to obtain a registered bright-blood image group; eliminating flowing void artifact to obtain an artifact-elimination enhanced black-blood image group; subtracting each image of the artifact-elimination enhanced black-blood image group from corresponding black-blood image to obtain angiography enhanced images; establishing a blood 3D model; establishing a vascular 3D model with blood boundary expansion; establishing an angiography enhanced 3D model by using the angiography enhanced images; obtaining an intracranial vascular enhanced 3D model based on the blood 3D model, the vascular 3D model and the angiography enhanced 3D model; and obtaining an intracranial vascular lesion recognition model based on the intracranial vascular enhanced 3D model. The method can simply, quickly and intuitively recognize the intracranial vascular lesions clinically.
