Abstract
Objective To check Bowie-dicktest(B-D) test strips quantitatively by using image entropy so as to reduce false negative risk of B-D test for the sterilizer. Methods In the past data of qualified B-D trial, 100 pot times negative B-D test strips were randomly selected, converted to digital images, and the image entropy was calculated respectively using MATLAB program. Results In the 100 samples for experiment, the entropy of 11 samples was between 5.8901 and 5.9502; that of 80 samples was between 5.9503 and 6.0120; and that of 9 samples was between 6.0121 and 6.0222, with 3 samples of slightly uneven color. Conclusion The image entropy value analysis combined with manual analysis can more accuratelydetect B-D test results for the sterilizer.关键词
