The integration of positron emission tomography (PET) and magnetic resonance imaging
(MRI) has been an ongoing research topic for the last 20 years. This paper gives an …

Attenuation correction (AC) is essential for the generation of artifact-free and quantitatively
accurate positron emission tomography (PET) images. PET AC based on computed …

Magnetic resonance (MR) imaging is a widely used medical imaging protocol that can be
configured to provide different contrasts between the tissues in human body. By setting …

Synthesizing a CT image from an available MR image has recently emerged as a key goal
in radiotherapy treatment planning for cancer patients. CycleGANs have achieved promising …

The cycleGAN is becoming an influential method in medical image synthesis. However, due
to a lack of direct constraints between input and synthetic images, the cycleGAN cannot …

Deriving accurate structural maps for attenuation correction (AC) of whole-body positron
emission tomography (PET) remains challenging. Common problems include truncation …

Attenuation correction (AC) of PET/MRI faces challenges including inter-scan motion, image
artifacts such as truncation and distortion, and erroneous transformation of structural voxel …

Accurate quantification of uptake on PET images depends on accurate attenuation
correction in reconstruction. Current MR-based attenuation correction methods for body PET …

Purpose Despite the proven utility of multiparametric magnetic resonance imaging (MRI) in
radiation therapy, MRI‐guided radiation treatment planning is limited by the fact that MRI …

In current combined PET/MR systems, PET attenuation correction is based on MRI, since the
small bore inside MRI systems and the strong magnetic field do not permit a rotating PET …
