Abstract:
Following thin slice reconstruction by multi-slice spiral CT,the initial data were processed in workstation.Reconstruction methods include two-dimensional multi-plane reconstruction,contour reconstruction,three-dimensional surface shielding,maximum density projection and volume rendering technique.The key parameters of 64-slice spiral CT involve parameters of monitor,time resolution,space resolution,high tension generator and thermal capacity of sucker.Its performance is influenced by many parameters.A balance of monitor,high tension generator and sucker can improve CT time resolution and rendering range.Multi-slice spiral CT multiplanar reconstruction and three-dimensional reconstruction image as important supplement of axial images can directly display fracture condition,and best and rapidly present joint peripheral fracture,providing reliable evidence for surgical protocol.Postoperatively reconstructed images can clear display internal fixtor appearance,location and fracture reduction,and is significant for surgical protocol and prognosis evaluation.
