阵列

Four aspects of research achievements include:(1)several imaging correction methods and strained estimation methods for biological tissues elasticity imaging were investigated as well as elasticity reconstruction and phantom, in vitro and in vivo elasticity imaging experiments;(2)in the fields of biological microsystem and perfusion evaluation for microvascular system, three kinds of microbubbles whose shell are albumin, sugar ester and surfactant respectively were designed and produced, then the methods to estimate the thickness of their shells were presented, moreover, the interacting mechanism of ultrasound contrast agents and tissues, as well as protein drug delivery under the condition of ultrasound sonification were studied in the molecular level;(3) At the aspect of high intensity focused ultrasound therapy system, we designed and constructed the 256-element HIFU transducers using 1-3 composite materials. And furthermore we developed the integrated HIFU system with 256-element HIFU transducers. And we made preliminary and important progresses in the research of HIFU bioeffect, lesion estimation, techniques of monitoring and imaging and characterizing of structure of HIFU transducer;(4)The real-time method of voice source regeneration based on compensative regulation of physiological parameters was investigated in the field of medical rehabilitation. We addressed the physiology and biophysics of vocalization, modeled voice source regeneration based on compensative regulation mechanism, and put forward an integrated evaluation about the speech rehabilitation and the regenerated voice source; Sixty-one archived journal papers were published, as well as ten in international journals, and eighteen publications were embodied by SCI.
