A GATE Monte Carlo model of the Philips Vereos digital photon counting PET imaging system using silicon photo-multiplier detectors was proposed. It was evaluated against experimental data in accordance with NEMA guidelines. Comparisons were performed using listmode data in order to remain independent of image reconstruction algorithms. An original ...

Intensity harmonization techniques (IHT) are mandatory to homogenize multicentric MRIs before any quantitative analysis because signal intensities (SI) do not have standardized units. Radiomics combine quantification of tumors’ radiological phenotype with machine-learning to improve predictive models, such as metastastic-relapse-free survival (MFS)...

Pour mettre en place une stratégie d’économie circulaire robuste et durable, il est indispensable d’en évaluer les impacts environnementaux. Valérie Laforest et Natacha Gondran, chercheuses à Mines Saint-Étienne, nous présentent l’intérêt d’intégrer une méthode d’évaluation absolue de la durabilité environnementale et le concept sous-jacent de « bu...

Determinantal point processes (DPPs) enable the modelling of repulsion: they provide diverse sets of points. This repulsion is encoded in a kernel K that we can see as a matrix storing the similarity between points. The usual algorithm to sample DPPs is exact but it uses the spectral decomposition of K, a computation that becomes costly when dealin...
