A method of creating and displaying images resulting from digital tomosynthesis performed on a subject using a flat panel detector is disclosed. The method includes the step of acquiring a series of x-ray images of the subject, where each x-ray image is acquired at different angles relative to the subject. The method also includes the steps of applying a first set of corrective measures to the series of images, reconstructing the series of images into a series of slices through the subject, and applying a second set of corrective measures to the slices. The method further includes the step of displaying the images or slices according to at least one of a plurality of display options.

A method of adaptively reducing noise within an x-ray image includes receiving raw data (R) representing a detected x-ray signal from an object. A counts-based modulation mask (Mcb) is generated in response to the raw data (R). In one embodiment, a structure dependent noise filtered image (Iblended) is generated in response to the raw data. A noise-reduced image (IF) is generated in response to the counts-based modulation mask (Mcb) and the structure dependent noise filtered image (Iblended). In another embodiment, a structure gradient mask (Mcs) is generated in response to the raw data (R). The noise-reduced image (IF) is generated in response to the counts-based modulation mask (Mcb) and the structure gradient mask (Mcs).
摘要:
Systems and methods are provided for optimizing visual consistency for a dataset of images by using observed and formulated display attributes. The formulated display attributes are derived from an analysis of a first set of images from the image repository. The formulated display attributes from the first set are combined with observer's display attributes to determine scaling factors. The optimized display attributes are then derived from the calculated scaling factors for a second set of images. In another aspect, a system and method is described where a digital image is processed in order to enhance viewing of the image on a display device in accordance to the optimized attributes associated with the observer.

Certain embodiments of the present invention provide a method and system for improved clinical workflow using wireless communication. A system for remote image display includes a data source with image data, wherein the data source is capable of transmitting the image data. The system also includes an identifiable display device capable of displaying image data transferred from the data source and a portable device capable of identifying the display device and requesting image data transfer from the data source to the display device without the transfer of the image data between the portable device and the data source. The system may also include an access point for relaying communication between the portable device and the data source. Communication between the portable device, the data source, and/or the display may include wireless communication, for example.
摘要:
Signal-adaptive noise reduction in digital radiographic images is described herein. Embodiments comprise methods for signal-adaptive noise reduction in digital radiographic images, comprising the steps of: obtaining raw x-ray image data of an imaged object; processing the raw x-ray image data to create processed x-ray image data; inputting at least one of the raw x-ray image data and the processed x-ray image data to an image processor; developing at least one of a first intensity modulation image from the raw x-ray image data and a second intensity modulation image from the processed x-ray image data; deriving a structure-dependent noise filtered image using the processed x-ray image data; performing signal attenuation-dependent blending; and creating a noise-reduced digital x-ray image therefrom. Computer-readable mediums encoded with programming for facilitating signal-adaptive noise reduction in digital radiographic images, and digital radiographic imaging systems comprising such programming, are also described.
