At least one processor is provided, in which the processor functions as a trained neural network that derives an estimation result relating to a composition of a soft tissue of a subject from a simple radiation image acquired by simply imaging the subject, or a DXA scanning image acquired by imaging the subject by a DXA method. The trained neural network learns using, as teacher data, two radiation images acquired by imaging the subject with radiation having different energy distributions, the radiation image of the subject and a soft part image representing the soft tissue of the subject, or a composite two-dimensional image representing the subject derived by combining a three-dimensional CT image of the subject, and information relating to the composition of the soft tissue of the subject.

An artificial replacement disk assembly comprised of a core in between two endplates. The endplates have outer surfaces that match the surface morphologies of the corresponding vertebral endplates. The endplates may have textured inner surface to form a strong fusion with the core during the fabrication process. The thick solid endplates strongly fused to the core create a very resilient implant. Gripping structures on the endplates may permit easy manipulation of the assembly during surgical procedures.

Methods and systems are described for determining body composition information. An example method can comprise receiving imaging data associated with a patient, causing the imaging data to be input into a convolutional neural network stored on one or more computing devices, determining, based on output data resulting from inputting the imaging data into the convolutional neural network, body composition information, and causing output of the body composition information.

A method for providing corrected x-ray images of a recording object and a correspondingly configured x-ray system are provided. In the method, a first x-ray image recorded prior to introducing a contrast agent and a second x-ray image of the recording object recorded after introducing the contrast agent are provided. A ring correction for eliminating ring artifacts is applied to the first x-ray image and the second x-ray image in each case. In order to provide corrected x-ray images with an improved image quality, provision is made with the ring correction of the first x-ray image for a ring image, which contains artifact data extracted from the first x-ray image, to be obtained and stored and for the ring correction of the second x-ray image for the ring image obtained with the ring correction of the first x-ray image to be used.

A method may include identifying a simulated three-dimensional representation corresponding to an internal anatomy of a subject based on a match between a computed two-dimensional image corresponding to the simulated three-dimensional representation and a two-dimensional image depicting the internal anatomy of the subject. Simulations of the electrical activities measured by a recording device with standard lead placement and nonstandard lead placement may be computed based on the simulated three-dimensional representation. A clinical electrogram and/or a clinical vectorgram for the subject may be corrected based on a difference between the simulations of electrical activities to account for deviations arising from patient-specific lead placement as well as variations in subject anatomy and pathophysiology.

A radiation imaging apparatus comprises an image generating unit configured to generate a material characteristic image by using a plurality of radiation images of different radiation energy levels; an evaluation information calculation unit configured to calculate evaluation information which indicates a correlation between a plurality of material characteristic images; and a scattered ray amount estimation unit configured to estimate, based on the evaluation information, an amount of scattered rays included in the plurality of radiation images.

A device for use with a four-dimensional radiological imaging modality includes: a base structure and a table slidably mounted with respect to one another. The base structure is at one end provided with a platform at an angle relative to the table, and a counteracting structure is arranged to apply to the table a load exerting force in a direction towards the one end provided with the platform from the opposite end of the base structure or vice versa.

An optimized press-fit between a resected bone and an articular implant may, for instance, reduce undesirable qualities, including excess micromotion, stress transmission, and/or strain. By taking into account heterogeneous bone properties, the parameters of a bone resection can be determined as to optimize the press-fit between a resected bone and an articular implant. An optimized press-fit is obtained by determining ideal engagement characteristics corresponding to the fit between the fixation features of an articular implant and a bone. Then, taking into account a bone's heterogeneous properties, the parameters of a bone resection that would substantially achieve the determined ideal engagement characteristics are determined.

A non-transitory computer-readable storage medium storing a program causes a computer to perform an analysis process based on a radiation moving image in which a dynamic state of a specific site of a subject is captured. The program includes the analysis process in which, an analysis is performed based on the radiation moving image wherein when a plane in which the specific site is movable is to be a movable plane, the radiation moving image is obtained by irradiating radiation on the specific site in a state in which the radiation is orthogonal to the movable plane.

A medical image processing apparatus includes at least one processor, and the processor acquires a purpose of examination of a target medical image to be interpreted. The processor detects a first abnormal shadow from the target medical image and displays a detection result of the first abnormal shadow on a display. The processor sets, according to the purpose of the examination, a first detection threshold value for detecting the first abnormal shadow or a first display threshold value for displaying the detection result of the first abnormal shadow.
