The aim of this study was to determine lower limb preference in 31 prosthesis users and 19 able-bodied controls on 11 goal-oriented tasks in free-standing and supported conditions. The action leg used in 6 or more tasks was considered the preferred leg. We hypothesized that the prosthetic leg in amputees would be used as the preferred leg as often as the dominant leg in controls. For prosthesis users in the free-standing condition, 65% used the prosthetic leg as the preferred leg. This was significantly different (p<0.003) from able-bodied controls, where 100% used the dominant leg as the preferred leg. This discrepancy became even more pronounced in the supported condition and was overall more prevalent among those who used prosthesis for more than 10 years. These findings may have implications for therapy and gait training. 相似文献

Type Ib synthetic diamonds were used as pulse-counting radiation detectors. When used as detectors to measure γ-rays, dose rates as low as 1 μGy h−1 were recorded, and the response was linear over five orders of magnitude. For best response, the diamonds were first primed with a large γ-ray dose and were then not exposed to light as exposure returned the diamonds to an “un-primed” state. The response was also shown to decrease with increasing the single substitutional nitrogen concentration. A boron doped layer, made by ion implantation to the surface of the diamond and used as the positive contact was necessary to eliminate count rate decreases due to space charge effects. 相似文献

对比剂智能跟踪与预试验肺动脉MSCT成像的对比研究 总被引:2,自引:0,他引:2
目的:探讨对比剂智能跟踪技术(BT)和预实验时间-密度曲线(PTDC)技术在CT肺动脉成像中的应用价值。方法:疑诊为肺动脉栓塞而行CT肺动脉成像(CTPA)的患者中,筛选出CTPA结果阴性的患者38例,其中采用BT法者20例、PTDC法者18例。BT法的兴趣区选在取主动脉弓上1cm水平的头臂静脉内,阈值设为100HU,触发后延迟3.2s开始增强扫描;PTDC法的兴趣区选在支气管隆突水平肺动脉主干内。采用双盲法对两种技术所得CTPA影像质量进行评分,并测量双上肺动脉与肺静脉、下肺动脉与肺静脉的密度差,进行统计学分析。结果:BT组图像质量评分优于PTDC组,但差异无显著性意义;右上肺前叶和右肺下叶的肺动、静脉密度差在两组间的差异没有统计学意义;左上肺前叶和左下肺下叶肺动、静脉密度差在两组间的差异有统计学意义(P值分别为0.008和0.019)。结论:选择头臂静脉BT法CTPA检查较PTDC扫描减少了对比剂剂量和患者受照剂量,而且图像质量好于PTDC法。 相似文献

An accurate determination of the penumbra of radiosurgery profiles is critical to avoid complications in organs at risk adjacent to the tumor. Conventional detectors may not be accurate enough for small field sizes. The Monte Carlo (MC) method was used to study the behavior of radiosurgical beam profiles at the penumbral region; the BEAM code was also used in this work. Two collimators (2.2- and 0.3-cm diameter) were calculated and compared with empirical measurements obtained with the detectors normally used. The differences found between film dosimetry and MC revealed a systematic error in the reading procedure. In the process, a water phantom was simulated with a layer of the same composition as that of the film. MC calculations with film differed by a small amount from those obtained with the water phantom alone. In conclusion, MC may be used as a verification tool to support dosimetrical procedures with conventional detectors, especially in very small beams such as those used in radiosurgery. Furthermore, it has been proved that the film energy dependence is negligible for fields used in radiosurgery. 相似文献
