目的 建立一种精确测量眼眶脂 肪体积的方法。方法 应用ImageJ软件计 算眼眶CT图像中的眼眶容积及眼眶脂肪体 积，在提取眼眶边界时分别采用手工描计 法及半自动方法。结果 半自动方法与手 工描计法计算结果大致相同，但更为精确 与省时。结论 ImageJ软件可精确测量眼 眶容积及眼眶脂肪体积。

Objective To found an accurate method in measuring the volume of orbital fat. Methods The volumes of orbit and orbital fat were measured by ImageJ software respectively. Manual and semi-automatic method were both used to display the margin of the orbit. Results The outcome of semi-automatic method was almost the same as the outcome of the manual method, and the former was more accurate and needed less time. Conclusions The volumes of orbit and orbital fat can be measured by ImageJ software accurately.
