查询词典 spiral

Firstly in this paper human mandibula was scanned by spiral CT. Then the data from CT was import into software (MIMICS 7.10) to reconstruct 3-D digital model. Software (Surfacer 10.5) was used to remove useless points , smooth the curves and output the STL file. The file was input into the rapid prototyping system, and was converted to slice format.
