Patent attributes
A respiratory gating phantom device includes a first airbag, a second airbag, a first catheter, a second catheter, a fixture, and an air pressure gating device. The first catheter and the second catheter are respectively installed in the first airbag and the second airbag. The fixture is provided with a phantom tumor and adjustably installed in the first catheter or the second catheter, thereby installing the phantom tumor in the first catheter or the second catheter. The air pressure gating device, connected to the first airbag and the second airbag, inflates and deflates the first airbag and the second airbag to simulate breathing. The first catheter and the second catheter respectively move along three-dimensional direction and two-dimensional direction in response to motions of the first airbag and the second airbag.
