查询词典 perfusion

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.

Results: In 2007, we provided 602 SPET/CT services in myocardial perfusion scan for attenuation correction and 202 SPET/CT services in other scans for image fusion. Among 64 regional bone SPET/CT services, we noted 2 (3.13%) significant motion artifacts and 2 (3.13%) streak artifacts induced by beam hardening effect while among 25 Ga-67 local SPET/CT services. According to the features including low tube currents and slow rotating speed of this SPET/CT, some problems such as the patient safety, longer scan time, alignment mismatch and radiation protection would be analyzed and discussed.

结果：2007年804例SPET/CT造影中，602例心肌血流灌注断层摄影进行衰减校正，共202例病例进行影像融合，其中鎝－99m-MDP局部SPET/CT发生「影像上明显可见的移动假影」的比例为3.13%(2/64)，镓－67局部SPET/CT发生移动假影的比钊则为24%(6/25)，因射束硬化效应所造成的条状假影有产生干扰融合影像判读的情形，其他问题包括SPET/CT之CT低管球电压及低转速之机器特性、受检者的安全、较长的造影时间、对位错误及辐射防护筝。
