Molecular imaging has experienced enormous advancements in the areas of imaging
technology, imaging probe and contrast development, and data quality, as well as machine …

Fibroblast activation protein inhibitor (FAPI) is an ideal diagnostic and therapeutic target in
malignant tumors. However, the knowledge of kinetic modeling and parametric imaging of …

Positron emission tomography (PET) imaging is widely used in medical imaging for
analyzing neurological disorders and related brain diseases. Usually, full-dose imaging for …

Purpose Partial volume effect (PVE) is a consequence of the limited spatial resolution of PET
scanners. PVE can cause the intensity values of a particular voxel to be underestimated or …

Deep image prior (DIP) has been successfully applied to positron emission tomography
(PET) image restoration, enabling represent implicit prior using only convolutional neural …

Background Positron emission tomography (PET) imaging encounters the obstacle of partial
volume effects, arising from its limited intrinsic resolution, giving rise to (I) considerable bias …

Objective. Low-count positron emission tomography (PET) imaging is an efficient way to
promote more widespread use of PET because of its short scan time and low injected …

Background Modern PET reconstruction algorithms incorporate point‐spread‐function (PSF)
correction to mitigate partial volume effect. However, PSF correction can introduce edge …

Objective To verify the visibility of physiological 18F-fluorodeoxyglucose (18F-FDG) uptake
in nuclei in and around the brainstem by a whole-body (WB) silicon photomultiplier positron …

Objective Non-blinded image deblurring with deep learning was performed on blurred
numerical brain images without point spread function (PSF) reconstruction to obtain edge …
