摘要： Pin-based support structures for easily and precisely assembling CT detector components into individual detector modules are described, as are methods of making the same. The pins in these structures serve as the local reference points against which all other detector components (i.e., collimators, scintillator packs, diodes, electronic flex connectors, etc.) are aligned. The pins may also be used to quickly and easily attach the individual detector modules to the local detector reference frame and then to the global reference frame in a CT imaging system. These structures allow CT detector components to be more easily and economically assembled than previously possible. Furthermore, these structures are extensible in the Z-direction, allowing for longer Z-coverage with each rotation of the gantry, thereby allowing for full organ imaging in a single CT scan.

摘要： An x-ray system is provided that produces noise at or below ambient levels. The system includes a positioning arm, an x-ray tube, an x-ray detector, and an acoustic dampening interface mounting between the x-ray tube and a first end of the positioning arm. The acoustic dampening interface may be a rubber isolator that absorbs the vibrations produced by the x-ray tube. The rubber isolator may include a rubber isolation tube positioned within a hole formed in a mounting plate of the x-ray tube. Alternatively, the rubber isolator may include a rubber washer and a rubber isolation layer, or isolation ring.
