1. A method for optimizing a projected vein image on a target skin surface of a patient using a vein imager, said method comprising:
forming the vein imager using: a housing for single-handed lifting and portable use of the vein imager; a first laser for emitting a first wavelength of light; a second laser for emitting a second wavelength of light; a scanner for scanning said emitted first wavelength of light and second wavelength of light from the first and second lasers in a pattern onto the target skin surface; one or more optical detectors for receiving a vein image formed by differential amounts of absorption and reflection of said emitted light at said first wavelength, and for converting the vein image into a signal; and using the second wavelength of light for projecting the received vein image onto the target skin surface of the patient using the signal;
positioning the vein imager above the target skin surface of the patient;
activating the vein imager and directing said scanned light from the vein imager toward the target skin surface;
centering said scanned light upon a selected vein of the target skin surface within one-half of an inch of either side of the selected vein; and
rotating the vein imager until orienting an axial direction of the vein imager perpendicularly to a direction of the selected vein of the target skin surface.
