摘要:

患者特定的心脏计算模型对于使用数字孪生有效实现精准医学和计算机模拟临床试验至关重要。心脏数字孪生可以为个体患者提供无创的心功能特征,因此有望用于患者特异性诊断和治疗分层。然而,解剖学和功能孪生阶段的当前工作流程,涉及从临床数据推断模型解剖结构和参数,不够高效、稳健和准确。在这项工作中,我们提出了一种基于深度学习的患者特定计算模型,它可以融合解剖学和电生理学信息来推断心室激动特性,即,传导速度和根结点。激活特性可以提供心脏电生理功能的定量评估,以指导介入手术。我们采用Eikonal模型生成模拟心电图(ECG)与地面真值属性训练的推理模型,其中特定的患者信息也被认为是。为了评估,我们测试了模拟数据的模型,并获得了普遍有前途的结果与快速的计算时间。

英文摘要:

Patient-specific cardiac computational models are essential for the efficient realization of precision medicine and in-silico clinical trials using digital twins. Cardiac digital twins can provide non-invasive characterizations of cardiac functions for individual patients, and therefore are promising for the patient-specific diagnosis and therapy stratification. However, current workflows for both the anatomical and functional twinning phases, referring to the inference of model anatomy and parameter from clinical data, are not sufficiently efficient, robust, and accurate. In this work, we propose a deep learning based patient-specific computational model, which can fuse both anatomical and electrophysiological information for the inference of ventricular activation properties, i.e., conduction velocities and root nodes. The activation properties can provide a quantitative assessment of cardiac electrophysiological function for the guidance of interventional procedures. We employ the Eikonal model to generate simulated electrocardiogram (ECG) with ground truth properties to train the inference model, where specific patient information has also been considered. For evaluation, we test the model on the simulated data and obtain generally promising results with fast computational time.
