Abstract: Methods and systems are provided for automatically generating an image quality score for a computed tomography (CT) image within an image quality assessment system. In one example, a method for an image quality assessment system comprises receiving a selection of a medical image from a user of the image quality assessment system; generating an image quality score for the selected medical image, the image quality score generated using a trained machine learning (ML) model; displaying the selected medical image and the image quality score in a graphical user interface (GUI) on a display device of the image quality assessment system; receiving an adjusted image quality score of the medical image from the user via the GUI; and using the adjusted image quality score to retrain the ML model.

Abstract: Various methods and systems are provided for automatically classifying a plurality of image slices using body region bounding boxes identified from a localizer image. In one embodiment, a localizer image may be mapped to a plurality of bounding boxes, corresponding to a plurality of body regions, using a trained machine learning model. Coordinates of the plurality of bounding boxes may be used to determine body region boundaries, such that the body regions are non-intersecting and coherent. The body regions identified in the localizer image may then be correlated to image slice ranges, and image slices within each image slice range may be labeled as belonging to the corresponding body region.

Abstract: System and methods for automatically identifying anatomical regions in medical images are disclosed. A signature is computed from one or more images of a patient. The signature comprises a water equivalent diameter distribution generated from one or more images of the patient. A best matching atlas element is identified from an atlas. The atlas includes a group of atlas elements, each atlas element includes landmarks associated with a set of image data, and a signature associated with the set of image data. The signature of the best matching atlas element matches the signature of the patient the best among the atlas. Landmarks of the best matching atlas element are projected onto an image of the patient. The method can be used on its own for anatomy localization or used in conjunction with another anatomy localization method to correct the result of another method.
