Abstract: The invention concerns an optical arrangement for an X-ray system for determining a patient position and/or a patient rotation of a patient to be X-rayed by the X-ray system, an X-ray system comprising such optical arrangement, a system for controlling and a method for determining a patient position and/or a patient rotation The optical arrangement comprises a laser source, and a detector vertically spaced apart from each other. The laser source is configured for emitting a horizontal laser line onto the patient, the detector is configured for detecting a course of the laser line emitted onto the patient. An analysing unit configured for determining the patient position and/or the patient rotation of the patient, based on an analysis of the detected course of the laser line.

Abstract: The quality of thoracic X-rays is depends on the inspiration state of an imaged patient. If the lungs of a patient are not significantly inflated during a thoracic X-ray, tissue from surrounding organs can cause the image to become cloudier, and the lung parenchyma is not effectively shown. Thus, there is a reliance on a medical professional to ensure that the patient is in an appropriate posture and inspiration state at the point of image exposure. This can be difficult with patients suffering from chronic conditions, though. Therefore, this application discusses a means to assess the inspiration state using the position of rib bones, and the diaphragm line in the X-ray image. Thus, an accurate estimate of inspiration state can automatically be reported to a medical professional, before a patient leaves the examination room, allowing an X-ray to be retaken, if necessary.
