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

Patent number: 5357549Abstract: The dynamic range of density or intensity values of pixels in an X-ray image is compressed in a manner preserving the range which is of primary interest for diagnosis, while still allowing recognition of detailed structure in the further ranges. This is accomplished by forming low-pass picture values (L) from input-picture values (E), determining equalizing values as a function (C) of the low-pass picture values (L) and forming output picture values by superposition of the input-picture values (E) and the equalizing values (C) . The equalizing values are chosen such that the output picture values are greater than the input-picture values (E) at relatively small low-pass picture values (L), below the range of primary interest, and the output picture values are less than the input-picture values at relatively large low-pass picture values (L), above the range of primary interest.Type: GrantFiled: October 22, 1991Date of Patent: October 18, 1994Assignee: U.S. Philips CorporationInventors: Hanns-Ingo Maack, Ulrich Neitzel
