CONTROL METHOD OF RADIATION TOMOGRAPHIC IMAGING APPARATUS, RADIATION TOMOGRAPHIC IMAGING APPARATUS AND PROGRAM |
| 摘要 |
A control method of a radiation tomographic imaging apparatus having a gantry rotating section equipped with a radiation tube including a liquid bearing and a rotor configured to support an anode and configured to rotate is provided. The control method includes a control step that is configured to start a rotation of the gantry rotating section at a second velocity slower than a first velocity, start control for stopping the rotation of the rotor, and control the gantry rotating section and the radiation tube so as to stop the gantry rotating section at a home position. The control method further includes a setting step configured to set at least one of the second velocity and the delay time such that a rotational angular position of the gantry rotating section at a time that the rotor stops rotation averagely varies when a shutdown is performed plural times. |

1. A control method of a radiation tomographic imaging apparatus having a gantry rotating section equipped with a radiation tube and a detector, the radiation tube including a liquid bearing and a rotor configured to support an anode and configured to rotate, the method comprising:
a control step that, when the radiation tomographic imaging apparatus is shut down, is configured to:
start a rotation of the gantry rotating section at a second velocity slower than a first velocity that is a velocity at an actual scan;start control for stopping the rotation of the rotor after a predetermined delay time has elapsed from a starting point of the rotation; andcontrol the gantry rotating section and the radiation tube so as to stop the gantry rotating section at a home position after the rotation of the rotor is stopped; and a setting step configured to set at least one of the second velocity and the delay time such that a rotational angular position of the gantry rotating section at a time that the rotor stops rotation averagely varies when a shutdown is performed plural times. |
