Section: claims

1. An imaging system, comprising:an X-ray imager;at least one X-ray sensor;an input interface for receiving an X-radiation scatter obtained by the at least one X-ray sensor during operation of the X-ray imager for imaging a first object;a processor configured to predict, based on the scatter, whether a second, not imaged, object is present in an examination room, wherein the at least one X-ray sensor is arranged away from the second object and configured to detect an additional scatter which is above a normal scatter to be expected if the second object is not present in the examination room other than the first object, or there is sufficient X-ray exposure of the first object if the normal scatter to be expected for the first object having a known mass is detected by the at least one X-ray sensor; andan output interface for outputting a predictor signal indicative of an outcome of said prediction. 2. The imaging system according to claim 1, further comprising a transducer configured to issue an alert signal in response to the predictor signal, said transducer being at least one of auditory and optical. 3. The imaging system according to claim 1, further comprising displaying on a display a message in relation to the predictor signal. 4. The imaging system according to claim 1, wherein a message in relation to said predictor signal is transmitted over a communication network to a recipient. 5. The imaging system according to claim 1, wherein an action is caused to affect the dose of X-radiation received at the first object based on the predictor signal. 6. The imaging system according to claim 1, wherein the X-ray imager comprises an X-ray detector for imaging the first object, and where the at least one sensor is different from said X-ray detector. 7. The imaging system according to claim 1, wherein the X-ray imager comprises an X-ray detector, wherein the at least one sensor is part of the X-ray detector. 8. The imaging system according to claim 1, wherein operation of the processor is based on a machine learning algorithm trained by one or more samples of X-radiation scatter measurements. 9. The imaging system according to claim 1, wherein the processor is configured to compare the scatter against one or more pre-defined X-radiation scatter thresholds. 10. The imaging system according to claim 1, wherein the X-ray imager is located in a room with the at least one X-ray sensor arranged on at least one of a wall, a floor, and a ceiling of said room. 11. The imaging system according to claim 1, wherein the at least one X-ray sensor is located on the X-ray imager. 12. A method of supporting X-ray imaging, comprising:receiving an X-radiation scatter obtained by at least one X-ray sensor during operation of an X-ray source of an X-ray imager to expose a first object to X-radiation for imaging;making a prediction, based on the scatter, whether a second, not imaged, object is present in an examination room, wherein the at least one X-ray sensor is arranged away from the second object and configured to detect an additional scatter which is above a normal scatter to be expected if the second object is not present in the examination room other than the first object, or there is sufficient X-ray exposure of the first object if the normal scatter to be expected for the first object having a known mass is detected by the at least one X-ray sensor; andoutputting a predictor signal indicative of an outcome of said prediction. 13. A non-transitory computer-readable medium having one or more executable instructions stored thereon which, when executed by at least one processor, cause the at least one processor to perform a method for supporting X-ray imaging, the method comprising:receiving an X-radiation scatter obtained by at least one X-ray sensor during operation of an X-ray source of an X-ray imager to expose a first object to X-radiation for imaging;making a prediction, based on the scatter, whether a second, not imaged, object is present in an examination room, wherein the at least one X-ray sensor is arranged away from the second object and configured to detect an additional scatter which is above a normal scatter to be expected if the second object is not present in the examination room other than the first object, or there is sufficient X-ray exposure of the first object if the normal scatter to be expected for the first object having a known mass is detected by the at least one X-ray sensor; andoutputting a predictor signal indicative of an outcome of said prediction.
