| Abstract: | The results on the agreement between microcomputer and experts for the diagnosis of pneumoconiosis from X ray films are presented in this paper.On a set of 200 films,the diagnoses made by the computer and by five experts were compared;From 100 films,the agreement rates were 83.5% for the normal/abnormal,73.0% for the four categories of profusion and 70.5% for the four categories of pneumoconiosis.From 100 films,the rates of agreament between the computer and the basic level consultation group were 86.0%,82 0% and 63.0% respectively.From 300 films for screening pneumoconiosis,the rate of agreement between the computer and the experts was 89.3%.The results demonstrate that the automatic diagnosis by computer is closer to the diagnosis made by experts. |
