学术报告题目：Computational Hemodynamics – From the Medical Imaging and Computational Simulation Perspectives

学术报告内容：

    Cardiac diseases remain a major cause of ill health and death in our society despite advancement in current clinical therapies. Due to the aging population and epidemic situation of obesity, the increase in incidence of heart diseases spurs forth the market for therapeutic systems that are computationally based and dedicated to the treatment of cardiovascular diseases. The shift in computing and flow visualisation technology for cardiac diagnosis is reported. As such, there will be an increasing demand for Computational Hemodynamic analysis technique to facilitate the prognosis and diagnosis of a failing heart. Hemodynamics parameters have the potential utility for clinical study of cardiac patients. The framework can be used to diagnose pre- and post- surgical treatments. In particular, fluid mechanically flow quantification can be adequately documented from simulated cardiovascular flow for diagnosis of the heart, cardiac flow analysis and medical imaging provides an alternative approach to characterize cardiac abnormalities. Future research will look at combining numerical simulations and various medical imaging devices or therapies, and building a more concise report on physiological abnormalities.

    Computational Hemodynamics (CHD) is the computer simulation of blood flow in the cardiovascular system. The motion of blood flow can be modelled by using Computational Fluid Dynamics (CFD) and interaction with blood vessel structure can be studied by combination with the use of Finite Element Method (FEM). This is becoming an emerging research field that may lead to a renaissance of computer modelling techniques for many biomedical engineering applications. The biomedical engineering industry comprises the health, pharmaceutical, and medical research fields, whereby interest is increasing in the use of CHD modelling for cardiac flow analysis, effectiveness of stents, and discovery of new phenomena related to physiological flows.

The cardiovascular modelling using the Computational Hemodynamics architecture is a complex and challenging process. At the front end of the process pipeline, medical imaging (MI) and computer aided design (CAD) normally come together to facilitate the geometrical reconstruction of cardiovascular structure for the flow modelling, in which the model geometry is then imported into the CFD platform to be used for blood flow modelling. Due to the interactive effect of vascular compliance and the blood flow properties such as pressure and pulsatility, the CHD model also encompasses the use of structural or FEM-based mechanics for fluid structure interaction (FSI). In the context of CHD, the FSI for cardiovascular applications solves a system of governing equations of both fluid and solid fields that is based on the mechanics of blood-vessel interaction. Advances in CFD and FEM technologies has been aided by the rapid developments in numerical models to reflect the true physics of flow, and the increase in computing power to perform the immense computational work for solution generation.

    Expertise in MI & CAD, CFD, and FEM, coupled with some basic medical science knowledge come together for the development of the CHD simulations. It is expected that this field demands a person who will proficiently obtain more or less some subsets of the knowledge from each of the disciplines.

    Each approach is strongly interlinked to each other and does not lie in isolation. Although experimental and analytical methods have been used in early stage, more recently, CHD is becoming more attractive to study the various aspects of biofluid dynamics and to assist medical engineers in the design of simulation processes involving blood flow and its interaction with the cardiac structures.
