为了解决尘肺病理诊断工作中人为因素的影响问题，作者采用计算机模拟技术，绘制了尘斑型尘肺肺切面的模拟图，并应用体视学定量分析的方法提出了尘斑型尘肺分期的体密度划分标准，对应于尘斑面积为１００％、７５％和５０％的尘斑体密度分别为４１．４、３１．Ｏ和２０．７。经用《尘肺病理诊断标准》提供的标准片进行检验，得到了满意的效果。作者建议在实际测量时使用小格边长为５ｍｍ的方格测试板。
In order to solve the problem of anthropogenic factors in the pathological diagnosis of pneumoconiosis, the authors used computer simulation technology to draw the simulated pneumoconiosis pneumoconiosis map and put forward the body density of the pneumoconiosis with dust-spot type by using stereological quantitative analysis method Divide the standard, corresponding to the dust spot area of 100%, 75% and 50% of the dust body density were 41.4,31. O and 20.7. By the “pneumoconiosis diagnostic criteria” provided by the standard tablets for testing, get satisfactory results. The authors recommend the use of square test panels with a small grid edge of 5 mm in the actual measurement.
