摘要： A method, computer system, and a computer-readable medium for registering one or more structures to a desired orientation for planning and guidance for surgery is provided. The method includes in a preoperative stage, obtaining one or more 3D models of one or more structures from one or more CT images using an image processing segmentation technique or a manual segmentation technique; in the preoperative stage, registering the one or more structures to a template that is adapted to an alternating registration for a patient-specific shape and pose for a desired reduction and corresponding reduction transformations; in an intraoperative stage, mapping the one or more structures to one or more radiographs via a 3D-2D registration that iteratively optimizes a similarity metric between acquired and simulated radiographs; and in the intraoperative stage, providing an output that is representative of a radiograph or a 3D tomographic representation to provide guidance to a user.

摘要： A method of generating a preview of at least one low-dose x-ray image includes the followings steps: obtaining an initial volumetric representation of a patient from an x-ray device; creating at least one x-ray image projection from the initial volumetric representation; injecting correlated noise into at least one of the x-ray image projections; and processing the noise-injected x-ray image projections to create at least one preview of a patient-specific low-dose x-ray for showing to a user. There are also described a device for generating at least one preview of a low-dose x-ray image, a corresponding imaging system, and a non-transitory computer readable medium.

摘要： Systems and methods for assessing a disease are provided. An input medical image in a first modality is received. Lungs are segmented from the input medical image using a trained lung segmentation network and abnormality patterns associated with the disease are segmented from the input medical image using a trained abnormality pattern segmentation network. The trained lung segmentation network and the trained abnormality pattern segmentation network are trained based on 1) synthesized images in the first modality generated from training images in a second modality and 2) target segmentation masks for the synthesized images generated from training segmentation masks for the training images. An assessment of the disease is determined based on the segmented lungs and the segmented abnormality patterns.

摘要： A system and method includes acquisition of one or more images of each of a plurality of bodies, each of the images associated with an acquisition time, determination, for each body, of a future health status of the body, the future health status of the body being a health status of the body at a time after the acquisition time of the one or more images of the body, and training of an artificial neural network to output a predicted health status, the training based on the one or more images and determined future health status of each body.

摘要： Systems and methods for generating a synthetic image are provided. An input medical image in a first modality is received. A synthetic image in a second modality is generated from the input medical image. The synthetic image is upsampled to increase a resolution of the synthetic image. An output image is generated to simulate image processing of the upsampled synthetic image. The output image is output.
