PET images reconstructed using the filtered backprojection (FBP) algorithm have the advantage of being unbiased but at the cost of exhibiting a high variance. The latter effect is often the dominant factor in clinical practice. Recently we have proposed new families of filters for FBP reconstruction that were designed so that the FBP reconstructions using these filters emulate the error properties...
Task-based selection of image reconstruction methodology in emission tomography is a critically important step when designing a PET protocol. This work concerns optimizing performance for a range of quantification tasks: finding the radioactivity concentration for different sizes of region of interest (ROI) and different group sizes. It is shown that there is a tremendous impact of ROI and group size...
