چکیده
Detailed knowledge of the hemodynamics in cerebral aneurysms is valuable not only for understanding their formation and rupture but also for clinical evaluation and treatment. However, important hemodynamic quantities are difficult to measure in vivo. In this paper we present a methodology for modeling patient-specific blood flows in cerebral aneurysms that combines medical image analysis and finite element methods. Intracranial aneurysms are segmented from either CTA or 3D rotational angiography images using implicit deformable models. Unstructured grids are constructed from the segmented images and computational fluid dynamics analysis are performed under realistic pulsatile flow conditions.

متن کاملThe Ethics of Global Catastrophic Risk from Dual-Use Bioengineering
Global catastrophic risks (GCRs) are risks of events that could significantly harm or even destroy civilization at the global scale. GCR raises a number of profound ethical issues, with a range of ethical theories suggesting that GCR reduction should be society’s top priority. This paper discusses GCR ethics in the context of dual-use bioengineering: bioengineering that can cause either benefit...
