Means for improving patient positioning during X-ray imaging

摘要

The present invention provides unique means and methods for improving patient positioning in relation to automatic exposure control (AEC) sensors before imaging takes place in an x-ray imaging system. The means for improving patient positioning comprises means adapted to project position and field size covered by the AEC system's sensors onto the patient in an X-ray imaging system provided with an x-ray tube, collimator provided with a light source, AEC system's sensors and an imaging device.
