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 1):
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; an alignment card comprising a pattern, said pattern comprising a material that emits a second wavelength of light when exposed to a third wavelength of light comprising a visible wavelength; 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 and to project said captured image contrast onto the field of view using said third wavelength of light; wherein said camera is further configured to capture said second wavelength of light emitted by said pattern when positioned in the field of view, and to capture said visible light at said third wavelength of light reflected from said pattern, said camera further configured to distinguish said third wavelength of light reflected by said pattern, from said second wavelength of light emitted by said pattern; and an image processor configured to align said projection of said image contrast with said image contrast formed by the differential absorption and reflection, using said distinction between said captured reflection of said pattern at said third wavelength of light, and said captured emission from said pattern at said second wavelength of light.
