An Automatic Framework for the Non-rigid Alignment of Electroanatomical Maps and Preoperative Anatomical Scans in Atrial Fibrillation

In atrial fibrillation, electro-anatomical maps (EAM) are used for ablation guidance. Yet, the anatomy reconstructed by the navigation system is known to be poorly accurate. This makes catheter navigation challenging and, as such, might affects ablation’s outcome. To ease navigation, existing systems allow co-registering EAMs with pre-operative MR scans by rigidly matching a set of manual landmarks. Nevertheless, the deformation between the two datasets is highly non-rigid. The aim of this work was therefore to develop a framework for the non-rigid alignment of EAMs and anatomical scans to improve ablation guidance

Cosa c’è di alternativo negli Alternative Food Networks? Un’agenda di ricerca per un approccio interdisciplinare

The paper outlines a framework of the existing literature upon Alternative Food Networks moving from four different although interrelated standpoints: territorial, environmental, economic, and sociological. The territorial perspective will highlight the modalities through which agri-food networks are organised at different geographical scales and affect the territories they are linked to. The environmental analysis will urge to go beyond a simple, even if very complex to study, “Life Cycle Assessment” to take into account the multi-functionality of farms and the territorial dimensions of the area where the supply chains is placed. The economic standpoint will outline the necessity to examine both the economic determinants of the farmers’ choice to use the AFNs and the mechanisms explaining why consumers are using, from the demand side, the same chains. Finally, the sociological analysis will point to the mechanisms through which quality conventions emerge and diffuse in AFNs.Il contributo presenta un inquadramento della letteratura sugli Alternative Food Network integrando quattro prospettive differenti per quanto interrelate: territoriale, ambientale, economica e sociologica. L’approccio territoriale pone in rilievo le modalità attraverso le quali le reti agro-alimentari si organizzano a diverse scale geografiche ed entrano in relazione con i diversi contesti territoriali. La prospettiva ambientale afferma la necessità di superare un approccio incentrato sul Life Cycle Assessment per l’analisi degli AFN, considerato eccessivamente riduttivo (per quanto complesso da realizzare), per considerare in alternativa la multifunzionalità delle aziende agricole e la dimensione territoriale dell’area in cui il network è sviluppato. L’approccio economico si propone di indagare sia le determinanti economiche della scelta di sviluppare una rete alternativa da parte degli imprenditori agricoli, sia i meccanismi per i quali i consumatori utilizzano le stesse reti. Infine, l’approccio sociologico si concentra sui dispositivi attraverso i quali il concetto di qualità viene definito e diffuso all’interno degli AFN
