The cooling system of the CT system includes a gantry and a table that moves an object into a bore of the gantry. The gantry includes part boxes mounted therein, and blade elements are formed in regions of the part boxes. The cooling system of the CT system includes a cooling method that includes a multiple cooling method including a stand-by mode and an operating mode. ## Claims ### Claim 1 A cooling system of a computed tomography (CT) system, comprising: a gantry having a bore therein; and a table that moves into and out of the bore of the gantry, wherein the gantry comprises a part box mounted therein, and blade elements that are formed in regions of the part box are arranged to control an air flow inside the gantry, wherein the part box is an external housing for a part, wherein the part comprises one or more of an X-ray generator, an X-ray detector, a data acquisition system (DAS), a power supplier, a heat exchanger (HX), an high voltage generator (HVG),or a wireless transducer for each part box, wherein the part box comprises an inlet hole and an exhaust hole arranged in one or more surfaces of the part box, and the blade elements are fixed on an inner surface of the part box, wherein one edge of each of the blade elements is exposed at a surface of the part box through the inlet hole, and another edge of each of the blade elements extends toward an inner side of the inlet hole of the part box, and wherein an extended portion between the one edge and the another edge in each of the blade elements is not visible through the inlet hole of the part box. ### Claim 2 (depends on 1) The cooling system of claim 1, wherein the blade elements are formed on the exhaust hole. ### Claim 3 (depends on 1) The cooling system of claim 1, wherein the gantry comprises a rotor that rotates with the bore as a center, and a stator that is stationary, and the part box is mounted in the rotor. ### Claim 4 (depends on 1) The cooling system of claim 1, further comprising an exhaust fan formed together with the blade elements. ### Claim 5 A cooling system of a computed tomography (CT) system, comprising: a gantry having a bore therein; and a table that moves into and out of the bore of the gantry, wherein the gantry comprises a part box mounted therein, and blade elements that are formed in regions of the part box are arranged to control an air flow inside the gantry, wherein the gantry comprises a rotor that rotates with the bore as a center, and a stator that is stationary, and the part box is mounted in the rotor, and wherein the blade elements comprise: a first blade element formed in the rotor; and a second blade element formed in the stator. ### Claim 6 (depends on 5) The cooling system of claim 5, wherein the first blade element is directly formed on the part box or a housing of the rotor. ### Claim 7 A method of cooling a computed tomography CT system having a gantry including a rotor, a stator and a part box arranged within the rotor, the method comprising: activating exhaust fans mounted in the gantry to cool the gantry during a stand-by mode when the rotor of the gantry is not rotating; and cooling the gantry during an operating mode when the rotor is rotating to control air flow inside the gantry by blade elements formed inside the gantry, wherein the part box is an external housing for a part, wherein the part comprises one or more of an X-ray generator, an X-ray detector, a data acquisition system (DAS), a power supplier, a heat exchanger (HX), an high voltage generator (HVG),or a wireless transducer for each part box, wherein the part box comprises an inlet hole and an exhaust hole arranged in one or more surfaces of the part box, wherein the blade elements formed in the gantry include: fixing the blade elements on an inner surface of the part box, exposing one edge of each of the blade elements at a surface of the part box through the inlet hole, and extending another edge of each of the blade elements toward an inner side of the inlet hole of the part box, and wherein an extended portion between the one edge and the another edge in each of the blade elements is not visible through the inlet hole of the part box. ### Claim 8 (depends on 7) The method of claim 7, wherein the exhaust fans are formed together with at least one of the blade elements. ### Claim 9 (depends on 7) The method of claim 7, wherein during an operating mode all of the exhaust fans are deactivated. ### Claim 10 (depends on 7) The method of claim 7, wherein during an operating mode at least one of the exhaust fans is active to provide additional cooling to the gantry. ### Claim 11 (depends on 7) The method of claim 7, wherein during an operating mode at least some of the exhaust fans are active to provide additional cooling to the gantry. ### Claim 12 A method of cooling a computed tomography CT system having a gantry including a rotor, a stator and a part box arranged within the rotor, the method comprising: activating exhaust fans mounted in the gantry to cool the gantry during a stand-by mode when the rotor of the gantry is not rotating; and cooling the gantry during an operating mode when the rotor is rotating to control air flow inside the gantry by blade elements formed inside the gantry, wherein the blade elements formed in the gantry include: forming a first blade element in the rotor; and forming a second blade element in the stator.
