Pulse-echo imaging technique can only play a role when high intensity focused ultrasound (HIFU) is turned off due to the interference between the primary HIFU signal and the transmission pulse. Passive acoustic mapping (PAM) has been proposed as a tool for true real-time monitoring of HIFU therapy. However, the most-used PAM algorithm based on time exposure acoustic (TEA) limits the quality of cavitation...
Early detection and diagnosis of high-risk vulnerable plaques can reduce the death rate attributable to atherosclerosis. Many attempts to identify plaques have focused on in vivo imaging techniques. Animal models with foregone plaque sites will be valuable to evaluate the validity of the imaging methods. However, in traditional balloon injury models, the sites and size of generated plaques are uncertain...
Early detection and diagnosis of high-risk or vulnerable plaques can reduce the death rate attributable to atherosclerosis. Many attempts to identify atherosclerosis plaques have focused on in vivo imaging techniques. An animal model with foregone plaque sites will be valuable to evaluate the validity of imaging method. Based on the “response-to-injury” hypothesis, lesions in the artery's endothelium...
Urban traffic structure is the core issue of urban transportation industry. Reasonable urban traffic structure can meet urban residential transit demand, and also reduce greenhouse-gas emission of vehicles so as to decrease negative environment impact. Based on the principles of low-carbon economy, a quantitative model for environmental impact of urban traffic structure is established in this paper,...
