Comparative 4 Methods of Tissue Air Ratio Finding of Breast Contours

Abstract

Purpose : To compare the TAR among 3 methods with standard method for work analysis.

Materials and Mathods : 100 contours of patients' breast cancer by simple random sam-pling the patients during 2000-2001. The data are performed by experiment. ANOVA statistic analysis are used for mean test and method of Scheffe are used for analysis of each pair of methods.

Results : It is shown that TAR values finding by the method 2 are different from standard method at the level of 0.01 statistic significance, but TAR values finding by the method 3 and 4 are not different from of standard (P 0.01).

Discussion : The results are very useful for determination of TAR values, more conven-ience and less time consuming in breast cancer.
