摘要： An apparatus for reconstructing or filtering medical image data is provided. The apparatus includes processing circuitry to receive a first medical image data and meta-parameters related to the first medical image data; apply the received meta-parameters to inputs of a first trained machine-learning (ML) network, e.g., a multilayer perceptron, to obtain, from outputs of the first trained ML network, tuning parameters of a second ML network (e.g., a convolutional neural network) different from the first ML network; apply the received first medical image data to inputs of the second ML network, as tuned by the obtained tuning parameters output from the first ML network, to obtain, from outputs of the second ML network, second medical image data; and output the second medical image data. In one embodiment, the first medical image data is magnetic-resonance k-space data and the second medical data is a magnetic-resonance image.

摘要： A medical diagnosis support device of an embodiment includes processing circuitry. The processing circuitry acquires first reference data based on first clinical data relating to a diagnosis result of an evaluation target and second reference data based on second clinical data relating to a comparison target diagnosis result for the evaluation target and performs an analysis process relating to the diagnosis result of the evaluation target based on the first reference data and the second reference data. The first reference data includes first data that has been referred to by a first user to obtain the diagnosis result of the evaluation target and second data that has been referred to by a diagnosis support system to obtain the diagnosis result of the evaluation target. The second reference data includes the first data that has been referred to by at least one of the first user and a second user different from the first user in order to obtain the diagnosis result of the comparison target.

摘要： An X-ray computed tomography imaging apparatus according to one embodiment includes processing circuitry. The processing circuitry obtains reconstructed image data corresponding to a second energy range including an energy range different from a first energy range. The processing circuitry infers motion-quantity information as to a region of interest included in the reconstructed image data, based on the reconstructed image data. The processing circuitry then corrects a quantity of motion of the region of interest included in reconstructed image data containing data corresponding to at least the first energy range, based on the motion-quantity information.

摘要： According to one embodiment, an ultrasonic diagnostic apparatus includes an ultrasonic probe and processing circuitry. The processing circuitry causes the ultrasonic probe to perform a first scan and second scan in a same scan sequence, wherein the first scan is for calculating a first index value based on a displacement of tissue by a shear wave that propagates through a living body, the second scan for calculating a second index value indicating an attenuation of a reflected wave signal of an ultrasonic wave applied into the living body. The processing circuitry generates a first image based on the first index value, and generates a second image based on the second index value. The processing circuitry causes a display to simultaneously display the first image and the second image.

摘要： In one embodiment, an X-ray diagnostic apparatus includes an X-ray source, an X-ray detector, an arm, and processing circuitry. The arm supports the X-ray source and the X-ray detector. The processing circuitry identifies a three-dimensional running direction of a blood vessel of an object from a plurality of images that are obtained by using the X-ray source and the X-ray detector to image the object from at least two different angles, and controls positions of the X-ray source and the X-ray detector by using the arm in such a manner that a target position of the blood vessel is imaged from the at least two different directions determined depending on the three-dimensional running direction.

摘要： A PET apparatus according to one embodiment includes processing circuitry. The processing circuitry acquires list mode data. The processing circuitry reconstructs a PET image based on the list mode data. The processing circuitry identifies first coincidence data that is obtained by coincidence counting by a first detector and a second detector that is different from the first detector from among a plurality of pieces of coincidence data included in the list mode data. The processing circuitry estimates a time lag amount between the first detector and the second detector based on TOF information included in the first coincidence data and the PET image.

摘要： A medical information management apparatus has processing circuitry configured to search medical information in a storage, when accepting a search request of the medical information including a key being an item of information regarding a patient and a value being contents of the key, and extract the medical information matching a search condition as condition-matched medical information; extract the key and the value from the condition-matched medical information, calculate a matching rate being a proportion of the value included in the condition-matched medical information to the entire medical information in the storage, and determine that the value is idiosyncratic information when the matching rate is equal to or less than a threshold set with respect to the key; and determine whether the key of the value determined to include the idiosyncratic information corresponds to an essential key which is essential in terms of a purpose of utilization.

摘要： An ultrasound automatic scanning system according to an embodiment includes an ultrasound probe, a mechanical mechanism, and processing circuitry. The ultrasound probe transmits and receives ultrasonic wave. The mechanical mechanism holds and moves the ultrasound probe while an ultrasonic-wave transmission-reception surface of the ultrasound probe is pointed to a subject. The processing circuitry acquires a distance between a body surface of the subject and the ultrasonic-wave transmission-reception surface of the ultrasound probe based on reflected wave data collected while the ultrasound probe is moved by the mechanical mechanism. The processing circuitry generates, based on information of the distance, locus information of movement of the ultrasound probe when ultrasound scanning is executed on the subject. The mechanical mechanism executes ultrasound scanning on the subject by moving the ultrasound probe based on the locus information generated by the processing circuitry.
