In this paper we explore a parallel implementation for fast calculation of a tomographic projection operator for content-adaptive mesh model (CAMM) image reconstruction. Previously we introduced 2D and 3D tomographic image reconstruction using a CAMM for single positron emission computed tomography (SPECT). The proposed parallel method is fast and allows incorporation of a non-uniform attenuation and distance-dependent spatial resolution of the imaging system. This implementation establishes a necessary step for the future development and practical use of the CAMM tomo-graphic reconstruction.
