[Three-dimensional reconstruction of human organs based on magnetic resonance imaging data].
OBJECTIVE
To build proper three-dimensional models of human organs for radiation dose calculation.


METHODS
Human organ models were built by contour reconstruction algorithm conforming to 4 criteria. The contours of the organs were extracted based on the contours of the reconstructed organ surfaces, and the three-dimensional models with smooth surface, exact structure and good visibility were completed by computer graphic techniques such as lighting, smoothing, and normal average.


CONCLUSIONS
Several organ models were successfully reconstructed, suggesting that this method is suitable for building three-dimensional digital human organ models which can meet the need for dose calculation.
