Abstract

This paper conducts a recalling in myocardial perfusion imaging (MPI) followed by a spatial dosimetric investigation of the 201Tl distributed at the myocardium.  Methods and Results: Radiological data manipulation was prepared and a computational heart voxelized model was assembled. A set of images from abdominal aorta and angiotomography of the thorax was set up providing anatomic and functional information for heart modeling in SISCODES code. A homogeneous distribution of Tl-201 was assumed into the heart wall. MCNP – Monte Carlo Code was used to provide the photon transport into the heart model taking into consideration the interactions into the tissues.  The spatial dose distribution and histogram dose versus volume are presented. An analytical alternative model was addressed to the data validation. Conclusion: The presently developed tools can produce spatial dose distribution in MPI. Especially, the dosimetry performed elucidates imparted dose in the myocardial muscle per unit of injected Tl-201 activity, which can contribute to future deterministic effect investigations.
