给出了一种基于一步相移法的水浸超声检测快速频域算法,以适用于液浸式相控阵成像。通过在阵列信号频域乘以相移因子,将阵列虚拟延拓至水浸工件表面,再进行单介质频域成像。相比时域延时叠加算法,节省了计算界面折射点的用时。对于垂直入射平面波检测,提出一种网格匹配的方法,通过调整傅里叶变换的点数,使阵列信号频域和图像频域的采样网格相重合,有效地减少了频域插值误差和伪像,进一步降低了运算次数.实验结果表明,网格匹配频域算法的运算次数仅为时域平面波算法的1/60,为水浸式超声实时检测提供了一种可行方案。

针对粗晶材料超声检测信噪比低的问题,提出了一种水平分置线性双阵列超声成像方法。将两个线阵超声换能器沿直线水平分置在待检区域表面两侧,用收发分离的信号采集模式,一侧激发,另一侧记录各通道数据,进行聚焦成像。相比单阵列和同位置双线阵检测,文中的方法有效地减少了背向散射信号对缺陷信号的干扰,提高了成像信噪比。在粗晶铜质试块上的成像实验结果表明,当缺陷距离阵列较近时,文中的方法优于单阵列和同位置双线阵方法,成像信噪比提高约5~10 dB;当缺陷距离阵列较远时,单阵列模式和同位置双线阵检测方法失效,但文中的方法依然可以识别缺陷。文中的研究为粗晶材料的超声检测提供了一种可行的方案。

Changes of plasma C-reactive protein in patients with craniocerebral injury before and after hyperbaric oxygenation： A randomly controlled study BACKGROUND： Plasma inflammatory factor, such as C-reactive protein, whose content is regarded as a sensitively pathological marked protein and quantitative indexes of central nervous system injury, has been paid more and more attention in clinic. OBJECTIVE： To observe the effects and clinical significance of C-reactive protein in patients with craniocerebral injury after hyperbaric oxygenation. DESIGN： Randomized controlled study. SETTING： Departments of Neurosurgery, Laboratory and Hyperbaric Oxygen, the Second Affiliated Hospital, Medical College of Shantou University. PARTICIPANTS： A total of 60 patients with craniocerebral injury were selected from Department of Neurosurgery, the Second Affiliated Hospital, Medical College of Shantou University from October 2006 to April 2007. There were 37 males and 23 females and the mean age was 26 years. All subjects were certainly diagnosed as history of craniocerebral injury. Patients hospitalized at 24 hours after injury, Glasgow Coma Score ranged from 3 to 12 points, and all patients were certainly diagnosed with CT or MR scanning. Patients and their relatives provided confirmed consent. All the subjects were randomly divided into hyperbaric oxygenation group and control group with 30 in each group. METHODS： Patients in the control group were treated with routinely neurosurgical therapy after hospitalization; however, based the same basic treatment in the control group, patients in the hyperbaric oxygenation group received hyperbaric oxygenation by using iced-wheel four-door 2-cabin air-compression chamber （made in Yantai） from 24 hours to 10 days after operation or injury. After entering the cabin, patients who had a clear consciousness breathed the oxygen by using face mask; contrarily, patients directly breathed the oxygen. Therapeutic project： Expression was increas
