Ultrasound to X-ray synthesis generative attentional network (UXGAN) for adolescent idiopathic scoliosis

•This work is designed to provide both ultrasound and X-ray images for scoliosis patients based on ultrasound scanning.•A generative attention network for synthesizing X-ray images from ultrasound images is first put forward in this paper.•The image synthesis quality is improved by designing attention mechanism and introducing adaptive instance normalization.•The feasibility of the generated X-ray images is verified through qualitative and quantitative evaluation indicators.
