Abstract:
An apparatus and method for insuring the proper alignment of a detected vein pattern and a projected vein pattern are disclosed. The apparatus enhances the visual appearance of veins so that an error that can lead to improper patient care or injury can be avoided.

Claim (Index 9):
A vein imaging system comprising:\n a light source that illuminates a field of view with a first wavelength of light comprising an infrared wavelength, to create an image contrast of one or more veins formed by differential amounts of absorption and reflection of said first wavelength of light by the one or more veins and surrounding tissue in the field of view; a camera configured to capture said image contrast of the one or more veins at said first wavelength of light; a projector configured to receive said captured image contrast and to project lines at an edge of each of the one or more veins in said captured image contrast with a second wavelength of light, said second wavelength of light comprising a visible wavelength; wherein said camera is further configured to capture said projected edge lines for the one or more veins at said second wavelength of light reflected from the field of view, and to distinguish said captured edge lines of the one or more veins at said second wavelength of light from the edge of each of the one or more veins in said contrasted image at said first wavelength of light; and an image processor configured to align said projection of said edge lines for each of the one or more veins with said reflected edge lines of the one or more veins.
