基于仿生模式识别的医学图像分割方法

提出了一种基于仿生模式识别的医学图像分割算法。该算法首先根据训练样本矢量确定Ψ³神经元的权值,并在此基础上构建多权值神经元网络;然后利用神经元网络完成样本在高维特征空间的最佳覆盖;最后根据覆盖结果进行识别、分割。实验结果表明,与传统医学图像分割方法相比,该算法具有更高的准确性和可靠性,更好的泛化能力。此外,该算法从“认识”的角度出发,可以有效融合先验知识,能快速准确地从医学图像中分割出感兴趣的区域,具有较高的智能性。     

Intoxicated witnesses and suspects: Procedures and prevalence according to law enforcement.

Legal psychologists have generally neglected intoxicated witnesses and suspects in their research. One possible reason is the lack of objective information about the prevalence and characteristics of this witness and suspect group. Also unclear is whether standard police procedures for dealing with intoxicated individuals exist and what these may be. The present survey was conducted to help fill this void. Law enforcement officers completed a survey about their experiences with intoxicated witnesses and suspects. Their responses provide clear evidence that dealing with intoxicated witnesses and suspects is common and that there are few standard procedures for handling such individuals. As our data strongly suggest that this group has a significant presence in law enforcement contexts, several research and policy questions are apparent. For example, if the intoxicated differ from sober witnesses and suspects, should this warrant uniquely tailored procedural recommendations? Findings from this survey are intended to spur and guide research aiming to provide useful guidelines to law enforcement on how to interact with this potentially vulnerable and underresearched group.

Spouses' use of pressure and persuasion to promote osteoarthritis patients' medical adherence after orthopedic surgery.

Objective: The authors investigated health-related effects of social control (influence) that spouses exert in relation to osteoarthritis patients' medical adherence after total knee replacement surgery. Patients' behavioral and emotional responses to control were examined as mediators of associations between spouses' use of two control strategies (pressure, persuasion) and patients' physical and psychological recovery. Design: The authors used a three-wave panel design with assessments at one month before surgery, 1 month and 3 months after surgery. Data were collected during in-person interviews with 70 married, older adult patients. Main Outcome Measures: Recovery outcomes were assessed as improvement in knee limitations and depressive symptoms at the 3 month follow-up. Results: Spousal pressure and persuasion at one month postsurgery were indirectly associated with patients' recovery outcomes through patients' positive emotional responses to control. Conclusion: Although there are often immediate behavioral benefits in response to partners' use of both pressure and persuasion, the long-term health effects of these strategies seem to be accounted for by their opposing links to positive emotions. Findings further refine theory on health-related social control in marriage. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

小波分析方法在医学图像融合中的应用

在临床的实际应用中,单模态的医学图像(CT,MRI)的3D重建不能提供医生所需要的足够信息. 由于成像机理不同和人体组织结构的高度复杂性,不同模态的医学图像提供了不互相覆盖的结构互补信息. 为此在医学图像配准的基础上提出基于小波变换的最大值融合规则,局部平均梯度融合规则,区域能量融合规则等算法. 通过对CT图像与MRI图像基于小波变换的不同融合规则及融合算子进行融合的实验结果比较表明,以区域能量融合规则作为准则的融合效果更好. 能够把这两种图像优点结合在一张图像上,这样能为病变提供准确的定位参照,能清晰地显示病变自身,对诊断和治疗更加有利.
