Magnetic resonance imaging (MRI) technology is the most advanced medical imaging technology,has been widely used in different tissues of the human body lesions,the most generally applied to human brain tissue.
Human brain MRI images through the means of three-dimensional reconstruction of magnetic resonance imaging equipment to obtain continuous images of the two-dimensional surface,and then between these two-dimensional image of the location and gray-scale information into the puter,the puter corresponding to the position and processing,Finally,the human brain display reproduction in whole or in part of a three-dimensional image information.Three-dimensional reconstruction of MRI images for the doctors to provide detailed three-dimensional images of the human brain for them from the multi-angle,multi-level observation and analysis.
In this paper,three-dimensional reconstruction of medical images of the key technologies involved - inter-slice interpolation technique.MRI fault introduces an overview of image interpolation,knowledge structure,and parison of several interpolation algorithm.From the subjective and objective evaluation of the relationship between the start of the interpolation algorithm to discuss evaluation system,try to use cubic spline interpolation method of image interpolation processing,the use of MATLAB to prepare the evaluation procedures and cubic spline interpolation procedures,through the inter-layer interpolation Image interpolation is worth to experiment and evaluation.
