One slightly concave cylindrical lens combination is used to change one laser beam into small sector in small angle, and one reflector projects the laser beam to prism driven by a motor to rotate in high speed to produce one reciprocating and scanning small sector plane.

采用微凹柱面透鏡組將激光光源發(fā)射的一束激光拉成具有微小夾角的小扇面亚洲国产美女网站，利用反射鏡將此激光束透射到由電機(jī)驅(qū)動的高速旋轉(zhuǎn)多面棱體上成熟丰满熟妇高朝XXⅩ，使激光束產(chǎn)生一個小扇形往復(fù)激光掃描光平面。

ET tube insertion procedures were performed on 59 pediatric patients aged newborn to 17 years (33 boys) due to cardiopulmonary arrest or impending respiratory failure. Ultrasound images were taken before and after the procedure in two-dimensional and time-sector modes using a portable ultrasonic machine. The subxiphoid window at the mid-upper abdominal — just beneath the xiphoid process and the lower margin of the liver — was used most often, with a wide transducer sector angle (90 degrees) for bilateral scanning of the diaphragm.
