This study was designed to compare the long-term clinical outcomes and costs between video-assisted thoracic surgery (VATS) and posterolateral thoracotomy (PT) in neonates and infants. This study enrolled 302 patients with isolated patent ductus arteriosus (PDA) from January 2002 to 2007 and followed them up until April 2010. A total of 134 patients(More)
The location and ischemia extent are two important parameters for evaluating the acute myocardial ischemia (AMI). A focused-transducer-based photoacoustic imaging method was employed to assess time-dependent AMI. Our preliminary results show that the photoacoustic signal could identify the myocardium. The intensity and area of photoacoustic images of(More)
The current study was designed to compare long-term clinical outcomes and costs between video-assisted thoracoscopic surgery (VATS) and transcatheter Amplatzer occlusion (TAO). This study enrolled 294 patients with isolated patent ductus arteriosus (PDA) from April 2002 to April 2007, and 290 of these patients were followed up until April 2010. Of the 294(More)
Embolus-related cerebral injury is still a serious adverse event after cardiopulmonary bypass (CPB). But there is no stable animal model for basic and clinical research purposes. We chose miniature pig to establish a stable animal model of embolus-related cerebral injury after CPB and verified the validity of results by correlating the histopathological(More)
Photothermal therapy is an effective means to induce tumor cell death, since tumor tissue is more sensitive to temperature increases than normal tissue. Biological responses depend on tissue temperature; target tissue temperature needs to be precisely measured and controlled to achieve desired thermal effects. In this work, a unique photoacoustic (PA)(More)
A method combining morphological granulometry with Mie theory to determine optical scattering in biological tissues was proposed. Otsu's method was applied to binarize phase-contrast images. Binary morphological granulometry was used to estimate size density distribution of the tissue samples based on the binary phase-contrast images. Our results showed(More)
A glasses-free 3D display with glasses-assisted quality is presented. Self-adaptive algorithm is employed to optimize system parameters, which is applied to design the micro structure of lens array and free form surface backlight units. Moiré contour map based on contrast sensitivity function is simulated and is manipulated by ameliorating the(More)
