Abstract: Among other things, one or more techniques and/or systems for calibration of a radiation system to compute a gain correction(s) are provided. A calibration procedure is performed during which a portion of the detector array is shadowed by an object, causing the detector array to be non-uniformly exposed to radiation. A portion of a projection generated from the calibration procedure and indicative of radiation that did not traverse the object is separated from a portion of the projection indicative of radiation that did traverse the object, and a gain correction(s) is computed from the portion of the projection indicative of radiation that did not traverse the object (e.g., and is thus indicative of radiation that merely traversed air).

Abstract: Among other things, a tire inspection system and method are provided. A radiation source and a detector array are configured to rotate about an axis of rotation. During a first examination of a tire, the tire has a first orientation relative to the axis of rotation, and during a second examination, the tire has a second orientation relative to the axis of rotation. For example, between the first examination and the second examination, the tire is at least one of shifted with respect to the axis of rotation or rotated about a tire rotation axis (e.g., perpendicular to the axis of rotation) to change the orientation of the tire relative to the axis of rotation. In this manner, imagery of the tire may be developed, which can be inspected to identify irregularities, etc., in the tire, for example.

Abstract: Among other things, a tire inspection system (100) and method are provided. A radiation source (116) and a detector array (118) are configured to rotate about an axis of rotation. During a first examination of a tire (104), the tire (104) has a first orientation relative to the axis of rotation, and during a second examination, the tire (104) has a second orientation relative to the axis of rotation. For example, between the first examination and the second examination, the tire (104) is at least one of shifted with respect to the axis of rotation or rotated about a tire rotation axis (e.g., perpendicular to the axis of rotation) to change the orientation of the tire relative to the axis of rotation. Such rotation and translation of the tire (104) are carried out by using a conveyer belt (114) and a robotic arm (602). In this manner, imagery of the tire (104) may be developed, which can be inspected to identify irregularities, etc. in the tire (104), for example.

Abstract: A reinforcement cord which comprises a first fiber (302) having a first radiation attenuation coefficient. The reinforcement cord also comprises a contrast agent applied to the first fiber. The contrast agent has a second radiation attenuation coefficient that is different (e.g., greater) than that of the first radiation attenuation coefficient. In some embodiments, the reinforcement cord is incorporated into a composite product, such as a tire. In some embodiments, the contrast agent improves and/or enhances the discernibility of the reinforcement cord in a composite product during a radiation examination, such as a computed tomography (CT) scan. A method of manufacturing the reinforcement cord is also disclosed.

Abstract: A scanner (200) includes a radiation source (202) that emits radiation that traverses a scanning region and a detector array (204), including a line of detectors (302), that detects radiation traversing the scanning region, wherein the radiation source and the detector array are located on opposing sides of the scanning region. The scanner further includes a mover (208) configured to move an object through the scanning region when scanning the object. The line of detectors (302) is configured to move in a plane, which is substantially parallel to the scanning region, in coordination with the mover moving the object, thereby creating a plane of detection for scanning the object.

Abstract: A CT detector cell is constructed to have diagonally oriented perimeter walls. With such a construction, the resulting CT detector comprised of such detector cells has improved spatial coverage (spatial density). The number of detector channels is also not increased despite the increase in spatial coverage. Moreover, the detector cells can be constructed without much variance from conventional fabrication techniques.
