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.

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.
