HighlY constrained backPRojection (HYPR) is a promising image-processing strategy with
widespread application in time-resolved MRI that is also well suited for PET applications …

Abstract Purpose Partial volume effects (PVEs) are consequences of the limited resolution of
emission tomography. The aim of the present study was to compare two new voxel-wise …

Purpose: Highly constrained backprojection‐local reconstruction (HYPR‐LR) has made a
dramatic impact on magnetic resonance angiography (MRA) and shows promise for positron …

Purpose Early deep-learning-based image denoising techniques mainly focused on a fully
supervised model that learns how to generate a clean image from the noisy input …

The recently introduced HYPR (HighlY constrained backPRojection) method allows
reconstruction of serial images from highly undersampled data. In HYPR, individual …

Dynamic positron emission tomography (PET) scans of short-time frames are required to
quantitatively estimate the uptake of PET ligands. Because such short-frame scans tend to …

Purpose The increasing interest and availability of non-standard positron-emitting
radionuclides has heightened the relevance of radionuclide choice in the development and …

PET allows the imaging of functional properties of the living tissue, whereas other modalities
(CT, MRI) provide structural information at significantly higher resolution and better image …

Current clinical dynamic PET has an effective temporal resolution of 5-10 seconds, which
can be adequate for traditional compartmental modeling but is inadequate for exploiting the …

One of the challenges in PET/MRI is the derivation of an attenuation map to correct the PET
image for attenuation. Different methods have been suggested for deriving the attenuation …
