1. An X-ray imaging system comprising:
- an X-ray radiation source;
a source controller coupled to the source and configured to command X-ray emission of X-rays for image exposures;
a digital X-ray detector configured to acquire X-ray image data without communication from the source controller, wherein the detector comprises a matrix of image pixels, and the detector is configured to detect the beginning of an X-ray exposure by both continuously sampling the matrix of image pixels and recharging the image pixels between sampling prior to and during the X-ray exposure; and
a portable detector control device configured to communicate with the digital X-ray detector.
