Method and apparatus for detecting electro-magnetic reflection from biological tissue
First Claim
1. A method for imaging an anatomical structure comprising the steps of:
- illuminating a biological target tissue with at least one monochromatic source within an infrared range;
detecting a directly reflected and singularly scattered image from said biological target tissue;
enhancing said image with a contrast enhancing element, wherein said enhancing step comprises enhancing with a digital processor filter; and
displaying said image on a monitor.

Abstract
A system and method is provided to view an anatomical structure such as a blood vessel in high contrast with its surrounding tissue. The system and method may be used to produce an image of an anatomical structure using reflected electromagnetic radiation singularly scattered from target tissue. The system and method may also provide same-side illumination and detection of reflected electromagnetic radiation in a convenient integral imaging device. The system and method may also provide helmet mounted imaging technology in a single integral helmet which allows the wearer to view an anatomical structure located within a patient such that the image is continuously oriented according to the orientation of the helmet wearer'"'"'s head. The system and method may also be used in the performance of venipuncture. The system and method may provide for improved contrast between any anatomical structure and its surrounding tissue for use in any imaging system.
