Prototype vein contrast enhancer

Two different prototype vein contrast enhancers (VCEs) have been designed and constructed. The VCE is an instrument that makes vein access easier by capturing an infrared image of peripheral veins, enhancing the vein contrast using software image processing, and projecting the enhanced vein image back onto the skin using a video projector. The prototypes use software alignment to achieve alignment accuracy between the captured infrared image and the projected visible image better than 0.06 mm.
