Abstract: An X-ray CT apparatus according to the embodiment executes an imaging according to an imaging protocol including one or more image elements corresponding to an imaging type. The X-ray CT apparatus includes an X-ray source, an X-ray detector and processing circuitry. The X-ray source radiates an X-ray. The X-ray detector detects the X-ray. The processing circuitry merges, when first and second imaging protocols are set, first and second imaging elements, respectively included in the first and second imaging protocols, corresponding to same imaging type into a single third imaging element, thereby generating a third imaging protocol including the third imaging element.

Abstract: A processing apparatus for a medical image that is obtained by a multi-energy CT scan according to an embodiment includes processing circuitry. The processing circuitry reconstructs a first image based on scan data that is obtained by a multi-energy CT scan. The processing circuitry causes a display to display side by side, with respect to an area of interest that is specified on the first image, a first numerical value obtained based on the first image and a second numerical value obtained based on a second image that is different from the first image and that is obtained based on the scan data.

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: A medical image diagnosis system includes an imaging apparatus and processing circuitry. The imaging apparatus applies one-time or multiple-time medical imaging to a subject to which a plurality of drugs having a tissue accumulation property, which corresponds to a tissue characteristic, are administered successively or simultaneously. The processing circuitry reconstructs one or a plurality of medical images, based on one or a plurality of set of raw data acquired by the one-time or multiple-time medical imaging. The processing circuitry estimates a tissue characteristic of a target region, based on a spatial distribution of the drugs rendered on the one or the plurality of medical images. The processing circuitry displays the estimated tissue characteristic.

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.
