肺泡显微切片的三维重建

THREE DIMENSIONAL RECONSTRUCTION OF THE SERIAL SECTION MICROGRAPH OF PULMONARY ALVEOLUS

本文讨论了对肺泡类软组织切片图象进行三维重建的方法，重点分析了显微切片图象各类噪声的去除方法及灰度校正、几何位置校正、形态校正的方法．其中几何位置技正一直是序列显微切片重建的难点．本文提出的金字塔异或指数自动配难方法大大缩短了几何位置技正时间．从利用体无绘制技术重建的肺泡组织的三维形态来看，该配难方法具有较高的精度．实验证明该重建方法也适用于其他空腔组织、软组织的重建．

A method of reconstruction of the pulmonary alveolus based on the serial microtomies is presented. It includes eliminating the noises, adjusting the gray level, correcting the geometric distortion and resuming the morphology. An Exclusive -Or Index registration method based on pyramid structure is proposed to accelerate the displacement correction. Experirnents show that this method is fit for the reconstruction of many other tlssues.
