- Abstract
Calorimetric dosimetry through digital holographic interferometry (DHI) is a homogeneous dosimetry method for measuring the absolute absorbed dose in non-opaque phantoms. Different methods have already been proposed for measuring the distribution of dose using this homogeneous calorimetric dosimetry technique. In this research work, a new, simple, and easy-to-use method for determining the total absorbed dose via DHI is proposed. The method is based on fringe detection, counting, and using our derived calibration equations to obtain the total absorbed dose values. To prove the capability of the method in accurate estimating of the absolute total absorbed dose, the dosimetry process in this technique is computationally modeled. It is shown that the mean relative error for the obtained total absorbed dose from high-energy electrons in PMMA phantom amounts to 4.8% by the proposed method.
