Abstract: The invention relates to an X-ray image analysis system (4) comprising an X-ray image input interface (8) and a computing unit (9). The X-ray image input interface (8) is configured to receive X-ray images (14) taken by an X-ray imaging system (1) comprising an X-ray source (2) and an X-ray detector (3). The computing unit (9) is connected to the X-ray image input interface (8) and configured to obtain at least one X-ray image (14) from the X-ray image input interface (8) and perform a scapula position detection, including inputting the X-ray image (14) into a trained machine-learning system, running the trained machine-learning system, and obtaining a scapula position. The computing unit (9) is further configured to transmit scapula position information from a scapula position information output interface (10) to a display (5). The invention further relates to an X-ray imaging system (1) comprising an X-ray source (2), an X-ray detector (3), an X-ray image analysis system (4) according to the above description, and the display (5) configured to receive and display the scapula position information as well as to a method for analyzing an X-ray image.

Abstract: There is provided a computer-implemented method for determining rotation of a patient's chest in a medical image. The method comprises: receiving the medical image of the patient; processing the medical image to determine scapular spatial data relating to the patient's scapula; and determining rotation of the patient's chest with respect to at least one reference axis using the scapular spatial data.

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. The analysing unit is configured for validating whether the determined patient position and/or patient rotation of the patient corresponds to a predetermined reference parameter, and wherein the analysing unit is configured for generating a feedback signal based on a result of the validation.

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.
