Modeling the adult female phantom in the supine and prone postures and initial dose assessment in breast cancer diagnosis with Neutron Stimulated Emission Computed Tomography

Abstract

-In this study, the delivered dose for breast cancer diagnosis by NSECT was assessed in two different configurations, using a model of a human whole body, which was simulated in the supine and prone positions. In the system with the phantom in the prone posture, the adjacent organ doses were considerably decreased. In total irradiation, the breast equivalent dose was less than 10 mSv, which is received in a typical chest CT scan. To apply NSECT as a low-dose clinical imaging system, improving the detection system is required.

3D imaging of the elemental concentration associated with a malignant tumor in breast cancer using Neutron Stimulated Emission Computed Tomography: a Monte Carlo simulation study

“…The adult female phantom, simulated in a prone posture with a pendant breast (Araghian et al, 2015), was used for imaging and dosimetry calculation. The breast of the phantom contained a malignant tumor.…”
