数字摄影——简法头颅特殊体位设计的可行性讨论

目的对数字摄影———简法头颅特殊体位设计的可行性讨论 ,找出此体位设计的理论依据。方法通过对头颅特殊体位如许氏位、梅氏位采用简法体位设计图像效果的分析及讨论 ,指出在常规x线摄影中一些特殊体位的获取简单方法。结果我们认为对于较复杂的头颅特殊体位可以以被摄部位为目的 ,而不必考虑更多的因素如 :头颅的头颅指数 ,角度的大小 ,做出相对位置的体位设计 ,可以更直观的一次性得到图像。结论此法与常规许、梅氏位显示方法所获得的图像显示效果相同 ,操作较简便、易于掌握

The discuss of feasibility to the simple way about special postural design of head in digital photography

Objective To discuss the feasibility of the special postural design of head in digital photography,and find out the theoretic gist of postural design.Methods By analysis and discussing the imaging effect of postural design about the head special position,such as schuller's position and mayer's position,we find out the simple way of x ray general checking in special position.Result The capture of special position,should not think over more factor,such as the exponent of head,angle size,et.It can be go to effect just need one step more intuitively,reduce workload and improve work efficiency.Conclusion The show way is sameness as general one,handle relatively and hold easy.
