title: [The computer-aided measurement of medullary canal in proximal femur].
abstract: This study was conducted to search the law of the parameters of medullary canal section shape in proximal femur. The methods of image-processing and taper-curve-fit mathematics were adopted in the acquisition of data and parameters. Computer-aided method and manual method were employed to measure 10 samples of section shape in proximal femur. The results showed that no significant difference was seen between the computer-aided method and manual method(P> 0.05). This approach could reduce man-made errors and process mass samples automatically by computer.
