摘要： A method and system for fusion of multi-modal volumetric images is disclosed. A first image acquired using a first imaging modality is received. A second image acquired using a second imaging modality is received. A model and of a target anatomical structure and a transformation are jointly estimated from the first and second images. The model represents a model of the target anatomical structure in the first image and the transformation projects a model of the target anatomical structure in the second image to the model in the first image. The first and second images can be fused based on estimated transformation.

摘要： Physically-constrained modeling of a heart is provided. Patient-specific data may be used to estimate heart anatomy locations. A model is applied to the data for estimation. For increased accuracy of estimation, the biomechanics of the heart, such as the valve, may be used to constrain the estimation. By applying a dynamic system between estimated anatomy locations of different times, the locations may be deformed or refined. The modeled heart and/or valve may be used to estimate hemodynamics. The resulting velocities or other motion information may be used to emulate ultrasound Doppler imaging for comparing with acquired ultrasound Doppler data. The comparison may validate the modeling.
摘要翻译： 提供了心脏的物理约束建模。 患者特异性数据可用于估计心脏解剖位置。 将模型应用于数据进行估计。 为了提高估计精度，可以使用心脏的生物力学（例如阀）来限制估计。 通过在不同时间的估计解剖位置之间应用动态系统，位置可以变形或改进。 建模的心脏和/或阀可用于估计血液动力学。 所得到的速度或其他运动信息可用于模拟超声多普勒成像以与获得的超声多普勒数据进行比较。 比较可以验证建模。
