| 内容記述 | A method to establish the relationship between CT number and effective density for therapeutic radiations is presented. We approximated body tissues to binary mixtures out of muscle, air, fat, and bone. Consequently, the relationship can be calibrated only with a CT scan of their substitutes, for which we chose water, air, ethanol, and potassium phosphate solution, respectively. With simple and specific corrections for non-equivalencies of the substitutes, the calibration accuracy of 1% will be achieved. The proposed method would offer accuracy, simplicity, and specificity required for a standard in radiotherapy treatment planning, in particular, with heavy charged particles. | |||||
