A C++ & Matlab-based PET simulation and reconstruction software, enabling realistic brain simulations, e.g. dynamic PiB PET imaging, based on the system matrix of the advanced brain-dedicated High Resolution Research Tomograph (HRRT) scanner.
- Analytic simulation (forward projection) of a static or a dynamic series of PET HRRT sinograms
- Begins with realistic computational human brain phantom
- Enables realistic, noisy simulations
- Statistical PET image reconstruction using 3D ordered-subset expectation maximization (OS-EM) algorithm
- Incorporate attenuation and normalization modeling
- Can simulate dynamic PET studies, with an initial table of kinetic K values; e.g. our default example performs dynamic PiB PET studies
