On the left is the T-Ring, purchased by COPA in the early 90s. It was a trusted tool for the practice for many years. The tool would snap 5-6 simultaneous photos on various aspects of the residual limb. Using those photos a 3D image would be generated to use in the CAD software program which ultimately results in a model of the residual limb carved from urethane foam.

On the right is your typical Apple iPad, with a structure sensor from Standard Cyborg attached to the camera portion. This tool utilizes 3D imaging techniques to capture the residual limb in space and measures numerous contours while in the “operating box”. From this image a raw STL file can be generated, spliced into many layers and finally 3D printed.

So which to use? Here at Capital O&P we use everything! Each patient is unique and we want to ultimately achieve the best fit. This means approaching each case with an open mind. We may unlock the iPad, unzip the T-Ring bag or even brake open a plaster bandage. Whatever it may be we are here to help!
