  • Patent number: 12136268
    Abstract: A search support system includes at least one camera, and a server capable of communicating with the camera. The camera transmits, to the server, a captured image of the object and image color information of the captured image. The server determines whether a search condition of the captured image set by a user includes a color condition of at least one of white, black, and gray. When the color condition is included in the search condition, the server excludes a captured image associated with the image color information indicating the black-and-white image among all captured images stored in the database from a search target, and outputs a search result including a captured image satisfying the search condition. When the color condition is not included in the search condition, the server outputs a search result including a captured image satisfying the search condition among all captured images stored in the database.

  • Patent number: 11534119
    Abstract: An analysis apparatus according to an embodiment includes an extraction unit, a calculation unit, and an evaluation unit. The extraction unit extracts a detection value in a tumor region, a blood region, and a muscle region from a nuclear medicine image of a subject administered with a drug containing a radiolabeled anticancer drug that works by accumulating in a tumor. The calculation unit calculates a first comparison value that is a comparison result between the detection value in the blood region and the detection value in the tumor region, and a second comparison value that is a comparison result between the detection value in the muscle region and the detection value in the tumor region. The evaluation unit evaluates an accumulation of the drug in the tumor, based on the first comparison value and the second comparison value calculated by the calculation unit.
