By inserting the iMET in an interlocking nail and place them into an ox femur bone, the light from the iMET is projected onto the bone surface as a bright spot indicating the location of the screw hole

Fig. 3

(a) By inserting the iMET-interlocking nail set into an amputated leg and turned on the light source, a vague light spot can be seen on the surface of the leg (circle). (b) The surgeon is cutting an incision to reveal the light spot that indicates the location of the screw hole. (c) The bright spot (pinpointed) emitted from the iMET indicates the position of the screw hole to be drilled and locked.
