| 摘要 |
Alignment systems and associated methods of using such systems to help aim an x-ray source at an x-ray detector are described in this application. The alignment systems can contain an electromagnetic radiation transmitter (or receiver) that is associated with the x-ray detector and an electromagnetic radiation receiver (or transmitter) that is associated with the x-ray source. Electromagnetic radiation produced by the electromagnetic radiation transmitter can be detected by the receiver and used to align the x-ray source and the x-ray detector in the x-ray device. In some configurations, the electromagnetic radiation transmitter contains a radio-frequency (RF) antenna (or antenna array) that is attached in a fixed position relative to the x-ray detector and the electromagnetic radiation receiver also contains an RF antenna (or antenna array) that is in a fixed position relative to the x-ray detector. Other embodiments are described.
