Simulation and data analysis of stereological modeling based on virtual slices / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To establish a computer-assisted stereological model for simulating the process of slice section and evaluate the relationship between section surface and estimated three-dimensional structure.</p><p><b>METHODS</b>The model was designed by mathematic method as a win32 software based on the MFC using Microsoft visual studio as IDE for simulating the infinite process of sections and analysis of the data derived from the model. The linearity of the fitting of the model was evaluated by comparison with the traditional formula.</p><p><b>RESULTS</b>The win32 software based on this algorithm allowed random sectioning of the particles distributed randomly in an ideal virtual cube. The stereological parameters showed very high throughput (>94.5% and 92%) in homogeneity and independence tests. The data of density, shape and size of the section were tested to conform to normal distribution. The output of the model and that from the image analysis system showed statistical correlation and consistency.</p><p><b>CONCLUSION</b>The algorithm we described can be used for evaluating the stereologic parameters of the structure of tissue slices.</p>
