Abstract: An imaging process capable of selectively enhancing visualization of soft tissues, for example, a tumor. The imaging process includes producing a hard tissue-enhanced image of a body containing both soft and hard tissues, wherein the hard tissue-enhanced image contains images of the hard tissues that are enhanced relative to the soft tissues. A radiographic image of the body and the soft and hard tissues thereof are then obtained, after which a weighted subtraction algorithm is performed between the radiographic image and the hard tissue-enhanced image to produce a soft tissue-enhanced image in which imaging of the soft tissues is enhanced relative to the hard tissues. The hard tissue-enhanced image may be produced by obtaining first and second initial radiographic images of the body including the soft and hard tissues, and then performing a weighted subtraction algorithm on the first and second initial radiographic images to produce the hard tissue-enhanced image.
