MR AutoAlign - Numaris XA31

MR AutoAlign – Numaris X Job Aid MR AutoAlign – Numaris X Job Aid The AutoAlign parameter specifies which AutoAlign matrices are used to align the clinical protocol selected. The displayed value is a composite of the AutoAlign region and an AutoAlign reference  AutoAlign  Detects Positions  Reliable Position Standards  Arbitrary Patient Positions  Different Ages  Pathologies and Intervention  Special 3D Scout Volume  AutoAlign detects position and orientation of predefined AutoAlign sub-regions in individual patient anatomy  AutoAlign is used in two different variants:  AutoAlign Scout Protocols – AutoAlign parameter is used to specify the anatomical region in which the AutoAlign matrices will be computed  AutoAlign Clinical Protocols – protocols that use only one of the AutoAlign matrices. Almost all protocols can be used as an AutoAlign Clinical Protocols Routine Parameter Card > AutoAlign 1. AutoAlign Options a.
