[HTML][HTML] Recent developments in time-of-flight PET

S Vandenberghe, E Mikhaylova, E D'Hoe, P Mollet… - EJNMMI physics, 2016 - Springer
While the first time-of-flight (TOF)-positron emission tomography (PET) systems were already
built in the early 1980s, limited clinical studies were acquired on these scanners. PET was …

[HTML][HTML] Advanced Monte Carlo simulations of emission tomography imaging systems with GATE

…, C Trigila, U Pietrzyk, S Vandenberghe… - Physics in Medicine …, 2021 - iopscience.iop.org
Built on top of the Geant4 toolkit, GATE is collaboratively developed for more than 15 years
to design Monte Carlo simulations of nuclear-based imaging systems. It is, in particular, used …

Iterative reconstruction algorithms in nuclear medicine

S Vandenberghe, Y D'Asseler, R Van de Walle… - … medical imaging and …, 2001 - Elsevier
Iterative reconstruction algorithms produce accurate images without streak artifacts as in
filtered backprojection. They allow improved incorporation of important corrections for image …

MRI-based attenuation correction for PET/MRI using ultrashort echo time sequences

…, M Lonneux, S Vandenberghe - Journal of nuclear …, 2010 - Soc Nuclear Med
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 …

Roadmap toward the 10 ps time-of-flight PET challenge

…, J Nuyts, S Surti, S Vandenberghe… - Physics in Medicine …, 2020 - iopscience.iop.org
Since the seventies, positron emission tomography (PET) has become an invaluable
medical molecular imaging modality with an unprecedented sensitivity at the picomolar level, …

[HTML][HTML] State of the art in total body PET

S Vandenberghe, P Moskal, JS Karp - EJNMMI physics, 2020 - Springer
The idea of a very sensitive positron emission tomography (PET) system covering a large
portion of the body of a patient already dates back to the early 1990s. In the period 2000–2010, …

[HTML][HTML] PET-MRI: a review of challenges and solutions in the development of integrated multimodality imaging

S Vandenberghe, PK Marsden - Physics in Medicine & Biology, 2015 - iopscience.iop.org
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 overview …

Functional brain connectivity from EEG in epilepsy: Seizure prediction and epileptogenic focus localization

…, E Carrette, P Boon, S Vandenberghe… - Progress in …, 2014 - Elsevier
Today, neuroimaging techniques are frequently used to investigate the integration of
functionally specialized brain regions in a network. Functional connectivity, which quantifies the …

Review of SPECT collimator selection, optimization, and fabrication for clinical and preclinical imaging

…, R Van Holen, S Vandenberghe… - Medical …, 2015 - Wiley Online Library
In single photon emission computed tomography, the choice of the collimator has a major
impact on the sensitivity and resolution of the system. Traditional parallel‐hole and fan‐beam …
