演題 : Hemodynamic Simulation Technology in Vascular Surgical Application
要旨 : Some work will be presented from the areas of his research interest below:
Hemodynamic research in cerebral vascular. Computational fluid dynamics
has been developed to simulate patient special vascular structures to study the
effects of morphology and blood flow on aneurysm formation and rupture. The
application of these techniques to patient specific models will yield additional
information to assess the probability of rupture of aneurysms with different
geometries. Research projects in this area are aimed at assisting vascular
surgeons in the management and treatment of unruptured aneurysms when detected
during medical imaging procedures. Additional research projects will combine
haemodynamic and mechanical analysis with molecular biomarkers.
Computational fluid dynamics in cardiovascular blood flow:
Patient-specific haemodynamic models have often been used to reveal the
haemodynamic details and energy efficiencies in cardiovascular patients. The
technology is expected for customisation of surgical design and objective
assessment strategies for performance evaluation, which are amongst the many
advantages of such surgeries. Interdisciplinary collaboration across the fields
of biomedical engineering, information technology, image processing,
bioinformatics and cardiovascular surgery are being applied to this problem.
Procedures involving congenital heart diseases (CHD, details in the following
section) are some of the most complicated surgical methods in cardiovascular
treatment due to the small size of patient hearts and presence of aortic arch
reconstruction following growth of the body. Computational haemodynamic studies
have been applied to the last stage of the CHD procedure and aimed at evaluating
the energy loss (EL) affecting cardiac workload.
