Abstract: An adjunct device and system which works in tandem with existing diagnostic imaging tools such as for medical diagnosis to enhance reliability of diagnosis with guidance for appropriate treatment or imaging devices for machinery (or other objects) and guidance for repair. The adjunct device initially analyzes an input image and either automatically or semi-automatically (with input from a grid of organ and anomalies) provides matching images for adjacent viewing and comparison. Where relevant, the device provides weighted possible diagnoses with advisory pathways for treatment or additional testing. The device and system include computer elements with stored medical data appropriate to the diagnostic tool being used and the body part(s) or objects, being diagnosed to provide the appropriate comparative image.
