In this work we propose a comprehensive study of Digital Stent Enhancement (DSE), from the analysis of the requirements to the validation of the proposed solution. First, we derive the stent visualization requirements in the context of the clinical application and workflow. Then, we propose a DSE algorithm combining automatic detection, tracking, registration and contrast enhancement. The most original parts of our solution: landmark segmentation and non-linear image registration are detailed. Finally, we validate the algorithm on a large number of synthetic and clinical cases. Performance is characterized in terms of automation, image quality and execution time. This work is, to the best of our knowledge, the first comprehensive article on DSE, covering problem statement, proposed solution, and validation strategies.
在这项工作中，我们从需求分析到提出解决方案的验证，对数字支架增强（DSE）进行了全面的研究。首先，我们从临床应用和工作流程的角度推导出支架可视化的要求。然后，我们提出了一种结合自动检测、跟踪、配准和对比度增强的 DSE 算法。我们的解决方案中最具创新性的部分：地标分割和非线性图像配准进行了详细描述。最后，我们在大量的合成和临床病例上验证了该算法。性能的特点是自动化、图像质量和执行时间。据我们所知，这是第一篇关于 DSE 的全面文章，涵盖了问题陈述、提出的解决方案和验证策略。
