  • Publication number: 20240099675
    Abstract: A medical image processing device includes processing circuitry. The processing circuitry sets a first energy bin at a k-absorption edge of a specific substance and sets a second energy bin and a third energy bin on both sides of the first energy bin. The processing circuitry generates a first medical image and a second medical image in which the specific substance is more emphasized using data of the energy bins. The processing circuitry outputs the medical images via an output interface. The processing circuitry sets a weighting for the data in the first energy bin when the second medical image is generated to be less than a weighting for the data in the second energy bin when the second medical image is generated and to be less than a weighting for the data in the first energy bin when the first medical image is generated.

    Abstract: According to one embodiment, a medical device operation method includes a monitoring step and an application step. In the monitoring step, a monitoring apparatus executes first CT imaging on a treatment target person into which a first drug particle with a suppressed onset of a treatment effect is introduced, and monitors an accumulation of the first drug particles in a tissue, based on spectral information acquired by the first CT imaging. In the application step, an application apparatus applies an action for exerting the treatment effect of the first drug particle to the first drug particle accumulating in the tissue, by using as a trigger an event that the accumulation of the first drug particles in the tissue satisfies an objective condition.
