【摘要】： 目的：研究在不同斷面(包括橫斷面、冠狀斷面和矢狀斷面)中肺內(nèi)管道(包括肺動(dòng)脈、肺靜脈和支氣管)的分布情況，并通過計(jì)算機(jī)二維圖像處理及三維重建得到肺內(nèi)管道的數(shù)字化三維模型，展示它們的立體構(gòu)型和位置關(guān)系，同時(shí)實(shí)時(shí)顯示肺內(nèi)管道系統(tǒng)三維立體構(gòu)型。 材料與方法：從中國數(shù)字化可視人體(Chinese visible human，CVH)斷面數(shù)據(jù)集中選取包含肺斷面的部分連續(xù)圖像(第460層至第701層)，在圖像配準(zhǔn)后，通過連續(xù)觀察的方法對(duì)不同的管道進(jìn)行觀察、分割，然后根據(jù)重建目的的不同將分割后圖像保存為不同的圖片序列，最后將二維圖片序列輸入三維重建軟件進(jìn)行三維重建，得到所需展示的三維模型。 結(jié)果：1．CVH數(shù)據(jù)集斷面圖像清晰，分辨率高，，斷面中可清楚顯示肺動(dòng)脈、肺靜脈及支氣管，最遠(yuǎn)可至第5級(jí)分支。三者中支氣管呈中心性分布；肺動(dòng)脈和支氣管伴行，右肺上葉和左肺上葉(除外舌葉的部分)的肺動(dòng)脈位于伴行支氣管的內(nèi)側(cè)，右肺中葉及左肺舌葉內(nèi)肺動(dòng)脈位于伴行支氣管的前外側(cè)，兩肺下葉肺動(dòng)脈位于支氣管的周圍；肺靜脈呈周圍性分布，不與支氣管及肺動(dòng)脈伴行。2．重建出了支氣管、肺動(dòng)脈及肺靜脈的三維數(shù)字化模型，可顯示它們的主干、葉和段的分支，最遠(yuǎn)可顯示至亞段級(jí)分支，在幾種管道同時(shí)顯示時(shí)，可立體展現(xiàn)管道之間的位置關(guān)系。 結(jié)論：CVH斷面數(shù)據(jù)集清晰顯示了肺動(dòng)脈、肺靜脈和支氣管在斷面分布；重建的肺動(dòng)脈、肺靜脈及支氣管三維數(shù)字化模型形象地立體展示了肺動(dòng)脈、肺靜脈及支氣管的三維構(gòu)型及管道之間的位置關(guān)系，并可實(shí)現(xiàn)三維實(shí)時(shí)顯示。
[Abstract]:Objective: to study the distribution of pulmonary ducts (including pulmonary artery, pulmonary vein and bronchus) on different sections (including cross section, coronal section and sagittal section). The digital three-dimensional model of lung duct was obtained by computer two-dimensional image processing and three-dimensional reconstruction to show their three-dimensional configuration and position relationship. At the same time, the three-dimensional configuration of lung duct system was displayed in real time. Materials and methods: selected partial continuous images (layer 460th to 701) of lung section from Chinese digitized visible human (Chinese visible human,CVH cross-sectional data set, after image registration, The different pipeline is observed and segmented by continuous observation method, then the segmented image is saved into different image sequences according to the purpose of reconstruction. Finally, the two-dimensional image sequence is input into the 3D reconstruction software for 3D reconstruction. Get the three-dimensional model that you need to show. Results: the cross-sectional images of 1.CVH data set were clear and high resolution. The pulmonary artery, pulmonary vein and bronchus could be clearly displayed on the section, and the furthest branches could be reached to the 5th grade. The bronchi showed a central distribution among the three. The upper lobe of the right lung and the part of the superior lobe of the left lung (excluding the part of the lingual lobe) are located on the medial side of the accompanying bronchus, and the middle lobe of the right lung and the medial pulmonary artery of the lingual lobe of the left lung are located on the anterolateral side of the bronchus. The pulmonary arteries of the lower lobe of both lungs are located around the bronchus. Pulmonary veins are circumscribed and are not accompanied by bronchi and pulmonary arteries. 2. Three-dimensional digital models of bronchi, pulmonary arteries and pulmonary veins have been reconstructed, showing the branches of their main trunk, lobes and segments, as far as subsegmental branches. When several pipes are displayed at the same time, the position relationship between the pipes can be shown stereoscopically. Conclusion: the distribution of pulmonary artery, pulmonary vein and bronchus in CVH cross-sectional data is clear. The reconstructed three-dimensional digital model of pulmonary artery, pulmonary vein and bronchus vividly shows the three-dimensional configuration of pulmonary artery, pulmonary vein and bronchi and the position relationship between them, and can realize three-dimensional real-time display.
