Journal ArticleDOI
Image quality in CT: From physical measurements to model observers.
Francis R. Verdun,Damien Racine,Julien G. Ott,M.J. Tapiovaara,P. Toroi,François Bochud,Wouter J. H. Veldkamp,Wouter J. H. Veldkamp,Alexander Schegerer,Ramona W. Bouwman,I. Hernandez Giron,Nicholas Marshall,Sue Edyvean +12 more
TL;DR: The spectrum of various methods that have been used to characterise image quality in CT: from objective measurements of physical parameters to clinically task-based approaches (i.e. model observer (MO) approach) including pure human observer approach are presented.
Journal ArticleDOI
Automated analysis of neuronal morphology, synapse number and synaptic recruitment
Sabine K. Schmitz,J. J. Johannes Hjorth,Raoul M. S. Joemai,Rick Wijntjes,Susanne Eijgenraam,Petra de Bruijn,Christina Georgiou,Arthur P.H. de Jong,Arjen van Ooyen,Matthijs Verhage,L. Niels Cornelisse,Ruud F. Toonen,Wouter J. H. Veldkamp +12 more
TL;DR: An automated image analysis routine using steerable filters and deconvolutions to automatically analyze dendrite and synapse characteristics in immuno-fluorescence images and is capable of batch analysis of a large number of images enabling high-throughput analysis.
Journal ArticleDOI
Development and validation of segmentation and interpolation techniques in sinograms for metal artifact suppression in CT
TL;DR: The new artifact suppression design is efficient, for instance, in terms of preserving spatial resolution, as it is applied directly to original raw data, and successfully reduced artifacts in CT images of five patients and in phantom images.
Journal ArticleDOI
Quantitative assessment of selective in-plane shielding of tissues in computed tomography through evaluation of absorbed dose and image quality
Jacob Geleijns,M. Salvadó Artells,Wouter J. H. Veldkamp,M. López Tortosa,A. Calzado Cantera,A. Calzado Cantera +5 more
TL;DR: The observed reduction of organ dose and total energy imparted could be achieved more efficiently by a reduction of tube current, and the application of in-plane selective shielding is therefore discouraged.
Journal ArticleDOI
Automated classification of clustered microcalcifications into malignant and benign types.
TL;DR: A fully automated method for classification of microcalcification clusters into malignant and benign types, and to compare the method's performance with that of radiologists' performance are designed and tested.
