A new method of trabecular bone tissue dosimetry.
A new method of trabecular bone tissue dosimetry has been developed using solid-state materials. For measurement of photon radiation doses, trabecular bone was modeled by a mixture of two substances, a thermoluminescent phosphor and a nonluminophor, each of which is dosimetrically equivalent to either trabecular or red bone marrow, and each of which has a particle size range appropriate for one of the two tissue types that it represents. The ratio of components corresponds to the ratio of red bone marrow and trabecular bone as determined in actual bone samples. Characteristics of the dosimetric models for a few types of trabecular bone are given. Equivalence of the dosimetric characteristics of the various mixtures of thermoluminescent and nonluminophor materials to the corresponding characteristics of various types of trabecular bone have been derived and verified by experiment.
