Introduction Automatic functional volume segmentation in PET images is a challenge that
has been addressed using a large array of methods. A major limitation for the field has been …

Purpose: Current respiratory motion monitoring devices used for motion synchronization in
medical imaging and radiotherapy provide either 1D respiratory signal over a specific region …

The prevalent availability of high-performance computing coupled with validated
computerized simulation platforms as open-source packages have motivated progress in the …

Purpose: To develop a motion correction for Positron-Emission-Tomography (PET) using
simultaneously acquired magnetic-resonance (MR) images within 90 s. Methods: A 90 s MR …

Respiratory and cardiac motion causes qualitative and quantitative inaccuracies in whole
body multi-modality imaging such as positron emission tomography coupled with computed …

Purpose: Respiratory motion modeling of both tumor and surrounding tissues is a key element
in minimizing errors and uncertainties in radiation therapy. Different continuous motion …

Purpose Sphericity has been proposed as a parameter for characterizing PET tumour volumes,
with complementary prognostic value with respect to SUV and volume in both head and …

Simultaneous PET and MR imaging is a promising new technique allowing the fusion of
functional (PET) and anatomic/functional (MR) information. In the thoracic–abdominal regions, …

Purpose The aim of this paper is to define the requirements and describe the design and
implementation of a standard benchmark tool for evaluation and validation of PET ‐auto‐…

Head motion occurring during brain PET studies leads to image blurring and to bias in
measured local quantities. The objective of this work was to implement a correction method for …
