  • Publication number: 20250336548
    Abstract: A medical data processing device according to an embodiment includes processing circuitry. The processing circuitry acquires estimated data related to a state of a biological organ at a first timing, and actually measured data indicating the state of the biological organ at the first timing. The processing circuitry calculates a parameter based on the estimated data and the actually measured data. The processing circuitry estimates a state of the biological organ in a predetermined time phase at a second timing different from the first timing based on the parameter and the estimated data in the predetermined time phase.

  • Publication number: 20250279178
    Abstract: A medical image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry obtains an organ model, in which the target organ for treatment is expressed, based on a medical image; identifies a treatment condition which represents a treatment-related condition including at least the treatment position in the organ model; estimates a post-treatment feature quantity based on the organ model and the treatment condition; decides on a display condition regarding the treatment position in the organ model based on the estimated feature quantity; and displays, in a display device, the organ model according to the decided display condition.

  • Publication number: 20240202919
    Abstract: A medical image processing apparatus includes processing circuitry. The processing circuitry acquires first feature data related to the structure of interest from first medical image data scanned at a first timing and second feature data related to the structure of interest from second medical image data scanned at a second timing, estimates the third feature data by estimating the structure of interest at the second timing by simulation based on the first feature data, and calculates a first feature value and a second feature value that is a local feature value more than the first feature value from the second feature data and the third feature data. The processing circuitry specifies a plurality of parameter sets based on optimization calculation having a loss function including the first feature value, and determines a parameter set of interest from the plurality of parameter sets based on the second feature value.

  • Patent number: 8225781
    Abstract: In order to control the amount of evaporation of discharged agent droplets and so that a user can inhale agent droplets having a constant diameter regardless of use environment, an inhalation apparatus includes an airflow path communicating with a suction port through which the user inhales an agent, an agent discharging portion configured to discharge an agent supplied to the airflow path, and a humidifier located outside the airflow path and configured to humidify an airflow in the airflow path generated by an inhalation of the user.

  • Patent number: 8082917
    Abstract: There is provided an inhaler that allows inhalation of droplets having a fixed diameter, regardless of the use condition of the inhaler. The inhaler allows a user to inhale medicine from a suction port thereof. The inhaler includes an air passage through which the medicine passes, the air passage being connected to the suction port, an opening attached to a medicine ejection portion for ejecting the medicine, and provided in a part of the air passage so that the ejected medicine is released into the air passage therethrough, a passage-length determining portion configured to determine the proper distance from the opening to the suction port in accordance with a size of droplets of the medicine ejected from the medicine ejection portion and/or an ejection frequency, and a passage-length changing mechanism configured to change the distance from the opening to the suction port.
