Abstract: According to one aspect of an exemplary embodiment of the disclosure, a system and method for determining the location of one or more regions of interest (ROIs) within one or more preshot images taken of an anatomy includes the steps of providing an imaging system having a radiation source, a detector, and a camera aligned with the detector. A control processing unit is operably connected to the radiation source, the detector and the camera to generate preshot images and a camera image(s) of the subject. The camera image and preshot images are employed to determine the location of one or more regions of interest (ROIs) within the preshot images, such that exposure parameters for the operation of the radiation source to obtain one or more main shots of the subject can be adjusted corresponding to the image data for the ROI from the one or more preshot images.

Abstract: The current disclosure provides systems and methods for intelligent selection of display settings, including window-width (WW) and window-center (WC), for medical images, using deep neural networks. The current disclosure may enable automatic selection of display settings for a medical image, based on a deep neural network's appearance classification of the medical image. In one embodiment, the current disclosure provides a method comprising, receiving a medical image, mapping the medical image to an appearance classification cell of an appearance classification matrix using a trained deep neural network, selecting a first WW and a first WC for the medical image based on the appearance classification and a target appearance classification, adjusting the first WW and the first WC based on user preferences to produce a second WW and a second WC, and displaying the medical image with the second WW and the second WC via a display device.

Abstract: According to one aspect of an exemplary embodiment of the disclosure, a system and method for providing an indication of the mode of operation of an X-ray imaging system operable in a fixed mode or an automatic optimization of parameter (AOP) mode, and an operational mode indication system including at least one of a visual indicator and an audio indicator. The selection of an operational mode for the X-ray system enables a control processing unit to activate the operational mode indication system in a first manner and in a second manner at least during the operation of the radiation source and the detector to provide an indication of a current mode of operation of the imaging system, wherein the first manner is readily discernable from the second manner.

Abstract: Various methods and systems are provided for x-ray imaging. In one embodiment, a method comprises acquiring an image of a subject, generating, based on the image and a plurality of parameters, a noise modulation map comprising an estimated amount of noise in each pixel of the image, selectively reducing noise in the image based on the noise modulation map to generate a final image, and displaying the final image. In this way, the radiation dose during imaging may be reduced while maintaining or even improving image quality.
