LIGHT AND SHADOW GUIDED NEEDLE POSITIONING SYSTEM AND METHOD

The embodiments of the present invention provide a system and method for light and shadow guided needle positioning. DICOM images of a patient are captured for identifying a point of insertion of a needle on the patient's body and a target point inside the patient's body. Needle coordinates are computed based on the captured DICOM images to position the mechanical arms. Light is projected at a particular angle on the needle to form shadows of the needle. Laser light beams are projected to form cross hair at the point of insertion. Images or videos of the point of insertion, shadow of the needle and the cross hair are captured and displayed on a monitoring unit. A virtual circle is projected on the displayed image and is aligned with the point of insertion, shadow of the needle and cross hair in order to insert the needle precisely.
