论文摘要
在临床应用中,准确估计医学图像的形状厚度至关重要。例如,心肌的厚度是心脏病诊断的关键之一。尽管数学模型可用于获得准确的密度厚度估计,但由于迭代求解器,它们遭受了沉重的计算开销。为此,我们提出了用于致密厚度估计的新方法,其中包括一个快速求解器,该快速求解器估算了二元环形形状的厚度和一个直接从原始心脏图像估算厚度的端到端网络。我们在三个心脏数据集和一个合成数据集中测试拟议的模型,从而实现了令人印象深刻的结果和所有的结果。进行厚度估计是没有迭代求解器或手动校正的,该估计比数学模型快100倍。我们还通过标准临床模型分析了不同心脏病理的厚度模式,结果证明了我们方法对基于厚度的心脏病诊断的潜在临床价值。
Accurate estimation of shape thickness from medical images is crucial in clinical applications. For example, the thickness of myocardium is one of the key to cardiac disease diagnosis. While mathematical models are available to obtain accurate dense thickness estimation, they suffer from heavy computational overhead due to iterative solvers. To this end, we propose novel methods for dense thickness estimation, including a fast solver that estimates thickness from binary annular shapes and an end-to-end network that estimates thickness directly from raw cardiac images.We test the proposed models on three cardiac datasets and one synthetic dataset, achieving impressive results and generalizability on all. Thickness estimation is performed without iterative solvers or manual correction, which is 100 times faster than the mathematical model. We also analyze thickness patterns on different cardiac pathologies with a standard clinical model and the results demonstrate the potential clinical value of our method for thickness based cardiac disease diagnosis.
