A computerised technique is described for the quantitative assessment of resorption cavities in iliac trabecular bone. Using an Ibas II image analyser, the original bone surface, eroded by bone resorbing cells, is reconstructed using a curve fitting technique that maintains a smooth continuity with the trabecular bone on either side of the cavity. Resorption depths are measured using an interactive elastic circle; all identified cavities are measured regardless of whether or not resorption is complete, and the measurements made include mean and maximum cavity depth, cavity length, area, and adjacent trabecular widths. Results in 13 normal subjects are presented. The technique is reproducible, simple to operate, relatively rapid, and can be applied to less sophisticated image analysis systems.
描述了一种用于定量评估髂骨小梁骨吸收腔的计算机技术。使用Ibas II图像分析仪，通过曲线拟合技术重建被骨吸收细胞侵蚀的原始骨表面，该技术与腔两侧的小梁骨保持平滑连续。使用交互式弹性圆测量吸收深度；对所有识别出的腔进行测量，无论吸收是否完成，测量内容包括平均和最大腔深度、腔长度、面积以及相邻小梁宽度。给出了13名正常受试者的结果。该技术可重复、操作简单、相对快速，并且可应用于不太复杂的图像分析系统。
