摘要： A method of overhaul of a component (20) includes comparing a component (20) to reference data to provide additive manufacturing data. Depositing material on the component (20) using an additive manufacturing device (24) based upon the additive manufacturing data to provide a first object. The depositing of material includes initially depositing a first material having a relatively high melting point, and then depositing a second material which has a melting point lower than the relatively high melting point of the first material. The depositing step further including heating the first and second materials with a laser to sinter the materials to the component (20). Then putting the component (20) into the furnace for a heat cycle. Then determining predicted characteristics of the first object, and comparing the predicted characteristics of the first object to the reference data to provide machining data. Then machining the first object using the machining data.

摘要： A system (800) and method (900) for calibrating a computed tomography (CT) scanner including scanning a calibration apparatus with a CT scanner (830), and determining a first scan edge of a first calibration layer, a second scan edge of a second calibration layer, and a floating point of an opening from the scan. The method (900) also includes determining a first scan dimension and second scan dimension measured in a longitudinal direction from the first scan edge to the floating point, and the second scan edge to the floating point, respectively. The method (900) also includes determining a first scan overhang based on a difference between the first scan dimension and the second scan dimension and comparing the first scan overhang to a calibration overhang. The method (900) also includes determining a first level of uncertainty for the CT scanner (830) based on the comparing.

摘要： A method of manufacturing a component (20) includes scanning a component using computed tomography to provide scanned data. Additive manufacturing data is developed using the scanned data compared to reference data. Depositing powder (40A, 40B) using an additive manufacturing device (24) based upon the additive manufacturing data to provide a first object, the additive manufacturing device (24) melting the powder (40). Determining predicted characteristics of the first object based upon the additive manufacturing data. The predicted characteristics of the first object are compared to the reference data to provide machining data. Machining the first object using the machining data then occurs. A system (99) for manufacturing a component (20) is also disclosed.

摘要： A CT imaging system (1000) is provided, including: a scanning channel (200) disposed in a first direction; a radiation source component (10) disposed on one side of the scanning channel (200), wherein the radiation source component (10) is used to emit radiation beams; a detector component (20) disposed on another side of the scanning channel (200), wherein the detector component (20) is disposed opposite to the radiation source component (10) and used to receive the radiation beams, and the radiation beams forms an imaging region between the radiation source component (10) and the detector component (20), wherein the detector component (20) includes at least two detection regions (21) and at least one blank region (22), the imaging region has a central cross-section of the radiation beams (31) extending through the radiation source component (10), and a position of the detection region (21) and a position of the blank region (22) are complementary with respect to the central cross-section of the radiation beams (31). The CT imaging system (1000) may obtain missing data through algorithm compensation, by means of rotational scanning and based on data symmetry, so as to obtain complete projection data to restore image information of an object to be inspected (100).

摘要： There is provided a method for scanning of an object in a scanning apparatus. The method comprises placing the object into a jacket which surrounds the object or a part of the object to be scanned. The volume of the jacket surrounding the object is solid or filled with a filling material. The jacket is disposed on a support of the scanning apparatus, so that the jacket is positioned between an imaging beam emitting element and an imaging beam receiving element oppositely disposed to either side of the support. The support is rotatable relative to the emitting and receiving elements about an axis of rotation to allow creation of an image from projections each taken at a different relative angle of rotation. The method further comprises operating the scanning apparatus at the multiple relative angles of rotation to produce an image of the object.
