用单张X光片生成任意新视角投影,减少辐射暴露

Novel-view X-ray Projection Synthesis through Geometry-Integrated Deep Learning

  • 融合几何与纹理特征,从一张投影推算新视角
  • 在肺部成像中实现高质量多视角合成
  • 适合需要减少拍摄次数的临床场景

X射线成像在医疗领域至关重要,为诊断、术中引导和临床决策提供内部解剖信息。传统方法需多个角度的投影以获取完整视图,导致辐射剂量增加和流程复杂。本文提出DL-GIPS模型,仅通过一张已有投影即可合成新视角的X射线投影。该模型通过调控初始投影中提取的几何与纹理特征,匹配目标视角,并结合一致的纹理信息,经先进图像生成过程合成最终投影。我们在肺部成像案例中验证了DL-GIPS框架的有效性与广泛适用性,展示了其在减少数据采集需求的前提下,推动立体与体积分辨成像的潜力。

原文摘要 · Abstract (English)

X-ray imaging plays a crucial role in the medical field, providing essential insights into the internal anatomy of patients for diagnostics, image-guided procedures, and clinical decision-making. Traditional techniques often require multiple X-ray projections from various angles to obtain a comprehensive view, leading to increased radiation exposure and more complex clinical processes. This paper explores an innovative approach using the DL-GIPS model, which synthesizes X-ray projections from new viewpoints by leveraging a single existing projection. The model strategically manipulates geometry and texture features extracted from an initial projection to match new viewing angles. It then synthesizes the final projection by merging these modified geometry features with consistent texture information through an advanced image generation process. We demonstrate the effectiveness and broad applicability of the DL-GIPS framework through lung imaging examples, highlighting its potential to revolutionize stereoscopic and volumetric imaging by minimizing the need for extensive data acquisition.
