1. A radiation computed tomography apparatus for obtaining a tomographic image of a patient, comprising:

  • a couch which is movable in a predetermined direction;

    a top board which carries the patient and is slidably arranged on said couch;

    a gantry which has an opening and acquires projection data of the patient by guiding the patient carried on said top board into the opening;

    reconstruction means for reconstructing the tomographic image of the patient by reconstructing the projection data acquired by said gantry in real-time;

    display means for displaying the tomographic image of the patient reconstructed by said reconstruction means in real-time;

    detecting means for detecting at least a direction of an external force applied to one of said top board and said gantry; and

    means for driving the one of said top board and said gantry, to which the external force is applied, in the direction of the external force on the basis of a detection value of said detecting means.
