Segmentazione RM arto basata sulla rilassometria
Responsabile: Marco Comerci, marco.comerciibb.cnr.it

Descrizione:
Questa attività comprende lo sviluppo, l'evoluzione e la messa a punto di uno strumento software che calcola velocità di rilassamento e densità protonica (immagini QMCI) voxel per voxel del ginocchio e del polso, posto che siano fornite un opportuno insieme di acquisizioni di risonanza magnetica, e segmenta i tessuti di varie strutture. La versione attuale, ottimizzata per 0. 25 Tesla, segmenta studi del ginocchio nei seguenti 6 compartimenti: Osso; Cartilagine; Muscolo, Grasso; Fluidi e Tessuto a bassa densità protonica. Il software fornisce informazioni volumetriche e rilassometriche di ogni compartimento. Evidenzia inoltre la velocità di rilassamento e densità protonica della cartilagine in un'immagine T1-w per mostrare meglio la patologia. Questa segmentazione basata su modello utilizza velocità di rilassamento, densità protonica e informazioni anatomiche. Il software è configurabile e può essere ottimizzato per varie situazioni ambientali, come diverse caratteristiche dello scanner e diverse regioni anatomiche (vedi anche Segmentazione RM cerebrale basata sulla rilassometria).
