1. An X-ray CT device comprising:
an X-ray source that irradiates an object to be imaged with an X-ray;
an X-ray detector that is disposed on one side opposite to the X-ray source with a position, at which the object to be imaged is to be disposed, interposed therebetween and detects the X-ray having passed through the object to be imaged; and
a rotary unit that supports the X-ray source and the X-ray detector and rotates the X-ray source and the X-ray detector together around the object to be imaged,
wherein a distance between the X-ray source and a predetermined reference position positioned in the object to be imaged is variable in a rotational radial direction of the rotary unit,
a distance between the reference position and the X-ray detector is variable in the rotational radial direction of the rotary unit, and
the X-ray source and the X-ray detector are configured to move in the rotational radial direction of the rotary unit.
