Non-radiative X-ray image generation method and device based on ultrasonic coronal plane image

Abstract

The invention discloses a non-radiative X-ray image generation method and device based on an ultrasonic coronal plane image, and the method comprises the steps: constructing and training a generation attention network of a spine ultrasonic image and a spine X-ray image; the generation attention network of the spine ultrasonic image and the spine X-ray image comprises a first generator network, a second generator network, a first discriminator and a second discriminator, and the first generator network and the second generator network are the same in structure and comprise an image encoder, an image decoder and an attention mechanism module. And inputting a spine ultrasonic coronal plane image obtained by ultrasonic scanning into the trained generation attention network of the spine ultrasonic image and the spine X-ray image to generate a corresponding spine X-ray image. Imaging of the corresponding spine in the X-ray state is achieved in a non-radiation mode, the method can be used for regular clinical screening of teenager idiopathic scoliosis, and therefore it is avoided that growth and development of teenagers are affected by X-ray radiation accumulation.

Description

technical field [0001] The present application belongs to the field of medicine and the field of deep learning technology, and specifically relates to a method and device for generating non-radiation X-ray images based on ultrasonic coronal images. Background technique [0002] Adolescent idiopathic scoliosis (AIS) is the most prevalent form of scoliosis, defined as a three-dimensional torsional deformity of the spine and trunk. Scoliosis occurs mainly during adolescence and causes lateral curvature, axial rotation, and sagittal normal curvature, lordosis, and kyphosis. Adolescents with AIS should be monitored regularly for early detection and further intervention, as rapid growth in adolescents may be at risk for development of crookedness. [0003] The gold standard for judging spinal deformity is to rely on standing X-ray film, and judge whether there is spinal deformation through the clear spine structure presented by X-ray film. But repeated X-ray monitoring can lead ...

Problems solved by technology

Unfortunately, the advantage of ultrasound imaging lies in the soft tissue structure, and bone components have a strong attenuation and scattering effect on ultrasound, so ultrasound bone images have the following characteristics: 1) The image information is less, because ultrasound cannot penetrate th
