Abstract: Computer-aided diagnosis techniques may be combined with techniques to obtain derived images from radiographic images to provide enhanced computer-aided diagnosis of, for example, lung nodules.

Abstract: A method of processing radiological images for diagnostic purposes involves the automated registration and comparison of images obtained at different times. A variation on the method may also use computer-aided detection (CAD) in conjunction with image parameters obtained during the process of registration to register CAD results.

Abstract: A user interface for facilitating a computer-aided diagnosis (CAD) includes an image input device that receives and scans the multiple images, and a film feeder that transports films from a film developer to the scanner. A multi-image identification input device uses bar code reading, numeric keypad, keyboard, network, and/or mouse to enter multiple image identification prior to image scanning. A display includes an image identification area, case processing status area, and a CAD detection and user modification area. The user can edit CAD results—accept, remove—and can add new diagnosis results to create a new composite diagnosis result.

Abstract: A method for identifying the orientation of an interesting object in a digital medical image comprises steps of creating a rectangular interesting image mask that covers the interesting object, based on the original digital medical image; generating a rough image based on the interesting image mask, the rough image coarsely describing the interesting object; and identifying the orientation of the interesting object based on the rough image. A method for segmenting interesting objects in digital medical images may also comprise steps of creating a rectangular interesting image mask that covers said interesting object, based on an original digital medical image; generating a rough image based on the interesting image mask, the rough image coarsely describing the interesting object; and performing a post-process on the rough image.

Abstract: A method of processing x-ray images in digital form comprises: (a) inputting an x-ray image in digital form; (b) determining one or more normalization factors based on the pixels of the input x-ray image; (c) performing normalization on the input x-ray image by applying the one or more normalization factors to the pixels; and (d) outputting a normalized digital x-ray image.
