Abstract: A method for radiographic imaging obtains a radiographic image of a patient's chest and processes the obtained image to generate a default radiographic image and a bone-enhanced image. At least a portion of one or more ribs within the default radiographic image is detected and a rib mask generated according to the at least the detected portion of the one or more ribs. The rib mask is applied to the bone-enhanced image to define masked enhanced image content that includes the detected at least the portion of one or more ribs. A composite image that combines the masked enhanced image content with the default radiographic image is generated and displayed.

Abstract: A method for obtaining a digital chest x-ray image of a patient, executed at least in part by a computer system, acquires a standard dose radiographic image and a reduced dose radiographic image, wherein the standard dose radiographic image and reduced dose radiographic images are obtained at peak kilovoltage values that differ by at least 10 kVp. A bone-enhanced image is formed by combining data from the standard dose radiographic image and reduced dose radiographic images and bone structure is segmented from the bone-enhanced image. A processed image is formed by suppressing bone contrast from the standard dose radiographic image according to the segmented bone structure. The processed image is displayed, stored, or transmitted.

Abstract: A method acquires a reconstructed tomographic volume image of anatomy of a patient and constructs a primary axis for a bone of interest in the imaged anatomy. The method forms a sectioned image of the bone in the volume image according to a first plane that is defined to extend along the bone and to extend through two or more articular surfaces. A primary axis for the bone is estimated, wherein the primary axis is midway between outer edges of the bone image that intersect the first sectioning plane. The bone is sectioned in the volume image by a second plane that is orthogonal to the first plane and that extends through the estimated primary axis. The method recalculates the position of the constructed primary axis according to the sectioning of the bone by the second plane. The recalculated constructed primary axis for the bone of interest is displayed.

Abstract: A method for clavicle suppression in a chest x-ray image. The method identifies the lung fields in the x-ray image and detects at least one portion of a clavicle ridge that lies outside the lung fields. Edges of a clavicle on each side of the detected clavicle ridge are detected, edge detection extended for the clavicle edges into the lung fields, and the clavicle defined within the x-ray image according to the edge detection. The clavicle is suppressed within the x-ray image to generate a clavicle-suppressed x-ray image and the clavicle-suppressed x-ray image is displayed, stored, or transmitted.

Abstract: A method for rib suppression in a chest x-ray image of a patient. The method detects and labels one or more ribs in a region of interest in the x-ray image that includes a lung region. The method obtains a rib model for one or more ribs of the image and modifies detection results for the one or more ribs by applying the rib model in the region of interest. A conditioned x-ray image is formed by suppressing rib content according to the modified detection results. The conditioned x-ray image is stored, displayed, or transmitted.

Abstract: A method for rib suppression in a volume chest x-ray image, executed at least in part by a computer captures a first set of unsegmented projection images, each at a corresponding angle, and forms a second set of segmented projection images by detecting rib features in a first projection image to form a first segmented projection image and generating a base model according to the detected rib features for the first projection image. Each of one or more additional projection images from the first set is processed to add members to the second set by a repeated sequence of generating a predictive model; detecting rib features using the predictive model; adjusting the base model according to detected rib features; and correcting rib detection in one or more members of the second set. The volume chest x-ray image is reconstructed according to the segmented projection images and is displayed.
