===Patient Casts for XtremeCTs===
Regardless of what cast is used, the X-, Y-, and Z- dimensions remain the same:
*X=14cm
*Y=14cm
*Z=designated 20cm distance in the scanner

Standard Scanco Distal Radius Cast
*Used for distal radius scans of 1-3 stacks.  Designed with the hand to be in a curved position.  The field-of-view allows for scanning of approximately the most distal 1/4 of the forearm.
Standard Scanco Distal Tibia Cast
*Used for distal tibia scans of 1+ stacks.  Designed with the foot to be in a flexed (upright) position.  The field-of-view allows for scanning of approximately the most distal 1/4 of the tibia.
Standard Scanco Sample Holder
*This is a cylindrical tube with a cut-out window on the top.  
*Allows for scanning small ex-vivo and other samples.  The tube provides support for the sample during scanning.  
*Also used for in-vivo scans of the hand along with a platform that conforms to the hand and slides into the tube.  
Elbow Holder
*Used for scans of the elbow.  Designed to support the forearm during scanning.
Knee Holder
*A long cylinder cast cut in half lengthwise and with a foot holder at the end.  This cast is designed to slide over the gantry tongue, placing the leg further into the gantry, in order to scan at distances closer to the core of the body.
*Used for distal femur and proximal tibia (i.e. knee) scans.
*Used for mid-shaft tibia scans.
*Used for larger ex-vivo and other samples.
