摘要： A medical information processing system of an embodiment includes a processing circuit. The processing circuit acquires medical examination data of a diagnosis subject and reply data of a medical examination by interview for the diagnosis subject. The processing circuit estimates a disease or symptoms of the diagnosis subject by inputting the examination data of the diagnosis subject to a trained model. The trained model is a model trained on the basis of a training data set in which diseases or symptoms that a learning subject suffers from are associated with examination data of the learning subject as correct answer labels. The processing circuit outputs a result of comparison between estimated data based on an estimation result of the disease or symptoms of the diagnosis subject and the reply data via an output unit.

摘要： A marker-coordinate detecting unit detects coordinates of a stent marker on a new image when the new image is stored in an image-data storage unit; and then a correction-image creating unit creates a correction image from the new image through, for example, image transformation processing, so as to match up the detected coordinates with reference coordinates that are coordinates of the stent marker already detected by the marker-coordinate detecting unit in a first frame. An image post-processing unit then creates an image for display by performing post-processing on the correction image created by the correction-image creating unit, the post-processing including high-frequency noise reduction filtering-processing, low-frequency component removal filtering-processing, and logarithmic-image creating processing; and then a system control unit performs control of displaying a moving image of an enlarged image of a set region that is set in the image for display, together with an original image.

摘要： A medical image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry acquires medical images of multiple time phases. The processing circuitry generates a vascular territory image showing plural vascular territories included in the subject tissue. The processing circuitry sets a region of interest in the subject tissue. The processing circuitry sets at least two regions out of the vascular territories and an ischemia area in the region of interest based on the vascular territory image. The processing circuitry calculates a ratio of each of the at least two regions to the region of interest. The processing circuitry outputs information about the ratio.

摘要： A medical information processing system of an embodiment includes a processing circuit. The processing circuit acquires examination data showing medical examination results with respect to a medical treatment subject and reply data showing reply results of a medical examination by interview with respect to the medical treatment subject. The processing circuit estimates information on medical treatment of the medical treatment subject by inputting the examination data of the medical treatment subject to a first model and estimates information on medical treatment of the medical treatment subject by inputting the examination data and the reply data of the medical treatment subject to a second model. The processing circuit outputs a first estimation result of the first model and a second estimation result of the second model via an output unit.

摘要： An X-ray diagnostic apparatus according to an embodiment includes an X-ray tube, an X-ray detector, image generating circuitry, and processing circuitry. The X-ray tube generates an X-ray. The X-ray detector is positioned in a manner facing the X-ray tube, and detects the X-ray. The image generating circuitry generates an X-ray image one after another, based on an output of the X-ray detector. The processing circuitry identifies an inserted object inside a subject in the X-ray image, by performing an image recognition process to the X-ray image. The processing circuitry sets the area to be searched for a marker, based on the inserted object identified in the X-ray image. The processing circuitry detects the marker in the X-ray image, by searching the area to be searched for the marker.

摘要： A medical image-processing apparatus of an embodiment includes a processing circuitry. The processing circuitry acquires a plurality of medical images including a predetermined region and having different time phases. The processing circuitry sets a first region of interest and a second region of interest in each of the plurality of medical images. The processing circuitry derives a temporal change in first pixel values, which are pixel values on the first region of interest, on the basis of the first pixel values and derives a temporal change in second pixel values, which are pixel values on the second region of interest, on the basis of the second pixel values. The processing circuitry sets a first time window on the basis of the temporal change in the first pixel values and sets a second time window on the basis of the temporal change in the second pixel values.
