Application of oblique supine body position for senile patients undergoing artificial total hip joint replacement 斜仰卧位在老年人工髋关节置换术中的应用
Methods: 42 patients with degenerative lumbar spine ( including 20 cases of degenerative lumbar spine instability complicated with vertebral canal stenosis, 18 cases with degenerative spondylolishesis and 4 cases with degenerative scoliosis) were examined by X-ray with A-P position, oblique position and dynamic lateral position. 方法:42冽病人,其中腰椎不稳合并腰椎管狭窄20例,退行性滑脱18例,退行性侧弯4例。
Methods To analyse X-ray images of lumbar vertebrae positive side and left-right oblique position plain films and CT images ( only 24 cases) of 82 patients. 方法对82例椎弓完整性腰椎滑脱症的正侧位、双斜位X线平片及CT图像(24例加作CT扫描)进行分析。
According to localizing herniation direction in the middle of 73 lateral protrusion's cases, right position was 41% and oblique position was 84.9%. 对73例手术证实为旁侧型椎间盘突出症患者的定位诊断中,正位像符合率为41.0%(30例),斜位像符合率为84.9%(62例)。
In the practical inspection the influence of the aperture and distance on the measurement accuracy of value K must be considered in order to precisely measure value K for the oblique probe and realize the accurate position of the defect. 在实际探伤中,要精确测定斜探头K值以实现对缺陷的准确定位,就必须考虑孔径和距离对K值测量精度的影响。
Conclusion The reasonable selection of oblique position with different angles can more clearly reveal the aneurysmal structure and its relation to neighbor vessels i.e.can improve the satisfactory degree of revealing aneurysms or detect rate. 结论合理选择不同角度的斜位,能更清晰地显示动脉瘤的结构及与周围血管的毗邻关系,提高颅内动脉瘤的显示满意程度和检出率。
Contralateral oblique position is helpful for superselective catheterization of internal iliac arteries. 对侧斜位有助于超选插管至髂内动脉及其分支;
Contralateral oblique view was the best projected position to show the opening and route of the internal iliac artery. 对侧斜位投照较正位和同侧斜位投照能更好地显示髂内动脉及其分支的开口和行程;
Application of Oblique Position in DSA DSA中斜位造影的应用探讨
Methods: 222 cases underwent selective or super-selective angiography and in the cases whose lesion was not shown or shown incompletely oblique position was taken. 方法:222例均先作选择性或超选择性造影,对没有显示病变或显示病变不完全的病例加摄斜位;
In the design graphics of agricultural machinery, we often deal with a oblique rod which plays a supporting role. In assembly drawing it is difficult to determine the form and position of the rod. 在农业机械的设计制图中,常涉及一根起支撑作用的斜杆,在装配图中由于它处于倾斜位置,难于确定它的形状和位置。
Based on homography in computer vision, a geometric correction method of oblique images due to tilt of camera position is discussed. 针对手持相机获得的图像倾角较大,并且摄取的前后图像之间存在旋转,提出了一种基于计算机视觉中单应原理的几何纠正方法。
Results After 6~ 18 months followed up, 76 cases of them, the oblique pelvis was recovered to natural position completely. 结果经6~18个月随访,78例患儿中,76例骨盆完全恢复正常,2例患儿虽经功能锻炼和皮牵引治疗但未能恢复。
