Patent ID: 8201999

Claim:
A radiation imaging apparatus, comprising: a supporting/moving means, for supporting a device, which is employed to perform radiation imaging, and for moving the device to predetermined positions at which radiation imaging is performed; an operating portion provided on the device, for manipulating the movement of the device which is supported by the supporting/moving means; detecting means, for detecting external forces which are applied to the operating portion, and outputs detection signals that represent the external forces; and control means, for controlling the supporting/moving means to move the device such that the movement tracks target values for movement, which are determined from the detection signals; the radiation imaging apparatus being configured to move the device by manipulating the operating portion to apply external forces thereon, and further comprising: measuring means, for measuring a unique oscillation frequency that represents the oscillation of the device in a state in which the device is being supported by the supporting/moving means; and unique oscillation component attenuating means, for causing the measuring means to execute measurements of the unique oscillation frequency and for attenuating signal components, which are included in control signals output by the control means to control the supporting/moving means and cause the movement of the device to fluctuate at the unique oscillation frequency, in real time.
