Virtual extrapolation technique for retracing line of response of single scattered events in positron emission tomography
Satyajit Ghosh, Pragya Das
Purpose: The scattering phenomenon creates degrading effects in positron emission tomography (PET) and the corresponding events are rejected conventionally. We have proposed a math…

Image reconstruction from tissue scattered events for coincidences in Compton-PET
Satyajit Ghosh, Pragya Das
For long time non-pure beta emitters are avoided from PET imaging due to extra dose and increase in background from Compton scattering. But advent of high-resolution Compton camera…

Doubly Robust Semiparametric Inference Using Regularized Calibrated Estimation with High-dimensional Data
Satyajit Ghosh, Zhiqiang Tan
Consider semiparametric estimation where a doubly robust estimating function for a low-dimensional parameter is available, depending on two working models. With high-dimensional da…
