A medical data processing method according to an embodiment includes inputting first medical data relating to a subject imaged with a medical image capture apparatus to a learned model to configured to generate second medical data having lower noise than that of the first medical data and having a super resolution compared with the first medical data based on the first medical data to output the second medical data.

A medical image processing method includes obtaining a first set of projection data by performing, with a first CT apparatus including a first detector with a first pixel size, a first CT scan of an object in a first imaging region of the first detector; obtaining a first CT image with a first resolution by reconstructing the first set of projection data; obtaining a processed CT image with a resolution higher than the first resolution by applying a machine-learning model for resolution enhancement to the first CT image; and displaying the processed CT image or outputting the processed CT image for analysis. The machine-learning model is obtained by training using a second CT image based on a second set of projection data acquired by a second CT scan of the object in a second imaging region with a second CT apparatus including a second detector with a second pixel size.

An inverter performs a power conversion operation for converting DC power into AC power, includes an arithmetic control device provided with a voltage command signal generation unit, a synthesis processing unit, and a carrier wave comparison unit. The voltage command signal generation unit has a plurality of control systems, and outputs the first voltage command signal generated based on the first control system among the plurality of control systems, and the second voltage command signal generated based on the second control system different from the first control system among the plurality of control systems. The synthesis processing unit generates a synthesized voltage command signal obtained by synthesizing the first voltage command signal and the second voltage command signal at a predetermined ratio. The carrier wave comparison unit generates a PWM signal which is a gate drive signal for controlling the power conversion operation based on the synthesized voltage command signal.
