Abstract: A computerized tomography apparatus is disclosed which reconstructs a tomography image of data from multi-directional projection data in a period of time less than the time required for a scan operation for data acquisition and displays the tomography image after a lapse of a given period of time from the termination of the scan operation. This avoids the time interval between scan and image display becoming irregular. Accordingly, tomography images can be displayed successively like motion picture to observe the internal movements of a section of a human body under examination in real time.

Abstract: A computer tomography apparatus of the present invention can select one of an ON state in which X-ray radiation is performed to continuously acquire projection data and an OFF state in which acquisition of projection data is stopped, and even in the OFF state, rotation of an X-ray tube is continued, thus allowing quick switching from the OFF state to the ON state.

Abstract: A capsule for a tooth-restoring material includes a cylinder containing therein the predetermined amount of a powder component of the tooth-restoring material and fitted at its rear end with an extruding plunger; a breakable package held in front of an extreme end opening in the cylinder, the package containing therein an amount of a liquid component of the tooth-restoring material and having its cylinder-facing side formed of a weak material; and a member for holding the package having a nozzle at its outermost end; wherein at a position of the plunger corresponding to the extreme end opening in the cylinder is provided a member capable of breaking through the package of a size small enough not to close up the opening and the nozzle, when the plunger moves to and reaches the package-holding member.
