Attenuation correction (AC) of whole-body PET data in combined PET/MRI tomographs is
expected to be a technical challenge. In this study, a potential solution based on a segmented …

The recently introduced first integrated whole-body PET/MR scanner allows simultaneous
acquisition of PET and MRI data in humans and, thus, may offer new opportunities, particularly …

Purpose In this study, the potential contribution of Dixon-based MR imaging with a rapid low-resolution
breath-hold sequence, which is a technique used for MR-based attenuation …

Introduction Positron emission tomography (PET) is the gold standard for non-invasive
assessment of myocardial viability and allows accurate detection of coronary artery disease by …

CT-based attenuation correction is a widely used option in commercial PET/CT scanners.
However, as a result of a nonsimultaneous acquisition and differences in temporal resolution …

This paper presents a new way of measuring complexity in variable-size-chromosome-based
evolutionary algorithms. Dealing with complexity is particularly useful when considering …

Purpose Spatial resolution in myocardial imaging is impaired by both cardiac and respiratory
motion owing to motional blurring. We investigated the feasibility of a dual cardiac–…

Integrated PET/MRI systems open exciting possibilities for clinical and research applications.
However, compared with PET/CT, PET/MRI is a complex technique resulting in new …

Purpose A critical question in the development of combined MR/PET scanners is whether MR
can provide the tissue attenuation data required for PET reconstruction. Unfortunately, MR …

We present a novel intrinsic method for joint reconstruction of both image and motion in
positron emission tomography (PET). Intrinsic motion compensation methods exclusively work …
