  • Publication number: 20240087119
    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.

  • Patent number: 11853093
    Abstract: In a power supply device, a voltage controller includes: a reference voltage circuit that generates a reference voltage based on an input voltage; a voltage control circuit that generates an output voltage of the voltage controller based on the input voltage by controlling an output current of the voltage controller so that the output voltage of the voltage controller corresponds to the reference voltage; and a first current detector circuit that detects the output current of the voltage controller, and generates a first current detection signal corresponding to the output current thereof. A current controller includes: a second current detector circuit that detects an output current of the current controller, and generates a second current detection signal corresponding to the output current thereof; and a current control circuit controls the output current of the current controller so that the second current detection signal corresponds to the first current detection signal.
