" Des systèmes d’imagerie médicale comme les appareils IRM demandent en général beaucoup d’électronique haute-performance pour fournir aux médecins les images précises et à haut contraste leur permettant de poser un diagnostic précoce de certaines maladies. Les gros appareils impliquent souvent des processus de balayage longs, pendant lesquels le patient doit rester complètement immobile, " déclare Steve Anderson, Directeur adjoint du segment High Performance Analog chez TI. "En s’appuyant sur notre expertise en termes de conversion de données et sur notre longue expérience en matière d’applications d’imagerie médicale, les fabricants peuvent exploiter les performances et le petit format de l’ADS5263. Ils peuvent ainsi proposer des équipements plus compacts et plus rapides, délivrant une qualité d’image remarquable, qui effectuent des balayages plus efficaces et offrent un confort accru au patient. "
\nLes modes de résolution à 14 et 16-bits permettent aux ingénieurs de basculer entre des opérations haute résolution à basse consommation ou à grande vitesse. En mode 16-bits, l’ADS5263 fournit des images nettes tout en maintenant une faible consommation d’énergie. En mode 14 bits faible consommation, l’ADS5263 réduit sa consommation presque de moitié:<\/p>\n
