Patent number: 10751016Abstract: 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.Type: GrantFiled: November 2, 2016Date of Patent: August 25, 2020Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Stewart Young, Jens Von Berg, Daniel Bystrov, Nataly Wieberneit, Ulrich Neitzel, Pallavi Vajinepalli, Biswaroop Chakrabarti, Soubhik Paul
