Abstract: An information processing device of an embodiment includes processing circuitry. The processing circuitry is configured to acquire a global model based on data sets regarding a plurality of cohorts, acquire a local model based on a first data set regarding at least one first cohort among the plurality of cohorts, calculate a weight based on a first data distribution with respect to the first data set and a second data distribution with respect to a second data set regarding the plurality of cohorts, and calculate an index value regarding the global model on the basis of the first data set and the weight.

Abstract: A medical information processing apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to obtain an image capturing a space in which a manipulation is being performed on an examined subject and non-image information related to at least one of the manipulation, the examined subject, or the space. Also, the processing circuitry is configured to detect a situation having a high possibility for an occurrence of an abnormality in the space, on the basis of the obtained image, the obtained non-image information, and first correspondence information. The first correspondence information indicates a correspondence relationship between two or more images capturing the space, non-image information, and abnormalities having a high possibility of occurring in the space.

Abstract: A medical image-processing apparatus according to an embodiment includes processing circuitry configured to determine a position of a feature point of a device in a first X-ray image, and generate a superimposed image in which a 3D model expressing the device is superimposed on the first X-ray image or a second X-ray image that is acquired later than the first X-ray image. The processing circuitry is configured to superimpose the 3D model on the first X-ray image or the second X-ray image at a position based on the position of the feature point.
