عنوان انگلیسی Determination of Average Glandular Dose in Mammography for Rh-Rh Mammogram Using Sobol-Wu Parameters in FORTRAN Code
چکیده انگلیسی مقاله Introduction: To write a computational program to calculate the average glandular dose in Mammography with Rh-Rh target-filter and also use it as an accurate and fast method of dose calculation founder different situations. Materials and Methods: In this research, the Sobol-Wu parameters are used to write a FORTRAN code for glandular dose calculation in Rh-Rh target-filter mammograms. The code calculates the glandular dose for Rh-Rh target-filter mammograms for the input parameters such as tube voltage in kV scale, half-value layer (HVL) of the incident x-ray spectrum in mm Al, breast thickness in cm and glandular tissue fraction (g). Results: The average glandular dose variation has been calculated against the voltage of mammogram X-ray tube for d = 5 cm, HVL = 0.35 mm Al and different value of g. Also the results related to the average glandular absorbed dose variation per unit roentgen against the glandular fraction of breast tissue for kV=28, HVL = 0.387 mm Al and different value of d are presented. Discussion and Conclusion: The results of this research are in good agreement with the computational results of J. M. Boone and the experimental results of E. L. Gingold et al. Also the code is fast, accurate and user friendly, that can be used for dose optimization in mammography imaging.
