Provided is a stationary source computed tomography (CT) architecture comprising: a detector disposed on a rotatable gantry; an x-ray source disposed on a fixed ring; wherein the detector is disposed on the gantry in a manner such that the detector is capable of rotating around a subject and of receiving a signal from the x-ray source. Embodiments of the invention include a CT-MRI scanner comprising the stationary CT architecture.

Analysis apparatus and analysis program

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.
