| 1 | Radiation exposure and reduction in the operating room: Perspectives and future directions in spine surgery显示文摘Intraoperative imaging is vital for accurate placement of instrumentation in spine surgery. However, the use of biplanar fluoroscopy and other intraoperative imaging modalities is associated with the risk of significant radiation exposure in the patient, surgeon, and surgical staff. Radiation exposure in the form of ionizing radiation can lead to cellular damage via the induction of DNA lesions and the production of reactive oxygen species. These effects often result in cell death or genomic instability, leading to various radiation-associated pathologies including an increased risk of malignancy. In attempts to reduce radiation-associated health risks, radiation safety has become an important topic in the medical field. All practitioners, regardless of practice setting, can practice radiation safety techniques including shielding and distance to reduce radiation exposure. Additionally, optimization of fluoroscopic settings and techniques can be used as an effective method of radiation dose reduction. New imaging modalities and spinal navigation systems have also been developed in an effort to replace conventional fluoroscopy and reduce radiation doses. These modalities include Isocentric Three-Dimensional C-Arms, O-Arms, and intraoperative magnetic resonance imaging. While this influx of new technology has advanced radiation safety within the field of spine surgery, more work is still required to overcome specific limitations involving increased costs and inadequate training. | Ankur S Narain Fady Y Hijji Kelly H Yom Krishna T Kudaravalli Brittany E Haws Kern Singh | 2017 | World Journal of Orthopedics2017，8，7： | 9 |
| 2 | 河北大麻坪超基性岩包体的岩石组构和地震波速各向异性显示文摘通过系统测定大麻坪尖晶石二辉橄榄岩、尖晶石方辉橄榄岩和含长二辉岩三类超基性岩包体中各主要矿物的晶格优选方位 (LPO) ,并用理论计算和实验测量得出地震波在岩石不同方向上的传播速度。结果表明 :1)大麻坪包体中橄榄石与斜方辉石的LPO方位关系与通常所见的[10 0 ]ol [0 0 1]opx,[0 10 ]ol [10 0 ]opx,[0 0 1]ol [0 10 ]opx不同 ;2 )大麻坪地区幔源包体的波速各向异性显著 ,岩石的波速各向异性特征与其宏观构造和微观组构一致 ,说明岩石组构是造成地震波速各向异性的决定因素 ;3)由地震波速推测的大麻坪地区的上地幔成分与包体出露的情况一致 ,即主体为二辉橄榄岩。 | 马芳 金淑燕 Kern H | 2001 | 北京大学学报(自然科学版)2001，37，4： | 2 |
