Abstract

This paper presents a novel approach to track objects from 4D-flow MRI data. A salient feature of the proposed method is that it fully exploits the geometrical and dynamical nature of the information provided by this imaging modality. The underlying idea consists in formulating the tracking problem as a data assimilation problem, in which both position and velocity observations are extracted from the 4D-flow MRI data series. Optimal state estimation is then performed in a sequential fashion via Kalman filtering. The capabilities of the method are extensively assessed in a numerical study involving synthetic and clinical data.

从4d血流MRI数据跟踪血管运动。

本文提出了一种从4d流MRI数据中跟踪物体的新方法。该方法的一个显著特点是它充分利用了这种成像方式提供的信息的几何和动态特性。其基本思想是将跟踪问题表述为数据同化问题，其中位置和速度观测都是从4d流MRI数据序列中提取的。然后通过卡尔曼滤波以顺序方式进行最优状态估计。该方法的能力在涉及合成和临床数据的数值研究中得到了广泛的评估。

期刊介绍： Cardiovascular Engineering and Technology is a journal publishing the spectrum of basic to translational research in all aspects of cardiovascular physiology and medical treatment. It is the forum for academic and industrial investigators to disseminate research that utilizes engineering principles and methods to advance fundamental knowledge and technological solutions related to the cardiovascular system. Manuscripts spanning from subcellular to systems level topics are invited, including but not limited to implantable medical devices, hemodynamics and tissue biomechanics, functional imaging, surgical devices, electrophysiology, tissue engineering and regenerative medicine, diagnostic instruments, transport and delivery of biologics, and sensors. In addition to manuscripts describing the original publication of research, manuscripts reviewing developments in these topics or their state-of-art are also invited.
