Publication number: 20200411150Abstract: In a conventional system for preparing reports on findings in medical images, the actual formulation of the report is not or only insufficiently supported by the computer-based system. Although there are efforts to improve such a system through automatic reporting, however, in previous systems, the error rate is too high and/or the operation of the system too complicated. This application proposes to provide text prediction to a user on the display device. The text prediction is based on prior analyzing the image content of a medical image at is displayed to the user at least when the user activates a text field shown on the display device via the input unit. The displayed text prediction is selected from a pre-defined set of text modules that are associated to the analysis result.Type: ApplicationFiled: December 24, 2018Publication date: December 31, 2020Inventors: AXEL SAALBACH, MICHAEL GRASS, TOM BROSCH, JENS VON BERG, STEWART YOUNG

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: 10631808Abstract: A biomarker of lung condition can conventionally be obtained using a spirometer. A spirometer provides an estimate of the volume of air expelled by the lungs. This is a rather indirect biomarker of the staging of a lung condition, because a reduction in lung volume may only manifest itself at a point where symptoms are well advanced. A lung condition such as Chronic Obstructive Pulmonary Disorder (COPD) is typically not visible on conventional X-ray attenuation images, because the relevant tissue (alveoli-bearing microstructured lung tissue) contains a lot of air. The X-ray dark-field can successfully indicate microstructure, such as lung alveoli. Therefore, imaging the lungs using the dark-field can provide information on the status of COPD.Type: GrantFiled: September 30, 2016Date of Patent: April 28, 2020Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Roland Proksa, Jens Von Berg

Publication number: 20200008768Abstract: Medical radiography requires specialist control of radiography equipment to achieve good imaging results. Typical errors that can occur consist of an inappropriate field of view being accidentally applied. This results in a “cropping effect” in which portions of the region of interest of a patient which would be of clinical use are omitted from the image. Conventionally, the only solution is to re-take the entire image with a more appropriate (and inevitably larger) field of view selected. This is undesirable, because it might require recall of the patient from another location, and the patient will be subject to two exposures, thus undesirably increasing their X-ray dosage. The present application proposes to use an anatomical atlas to analyse an X-ray image output from an initial exposure, in particular to assess whether significant anatomical elements are missing from the image.Type: ApplicationFiled: December 12, 2017Publication date: January 9, 2020Inventors: STEWART YOUNG, DANIEL BYSTROV, JENS VON BERG

Publication number: 20190362852Abstract: In modern health systems, and particularly in those in developing countries, primary care-givers located remotely from diagnosticians are increasingly turning to the possibilities afforded by social media and improved communication techniques. In particular, medical information may be obtained from a patient of the primary care-giver, and transmitted (for example, by email) to a diagnostician. However, the primary care giver has no way to know that the diagnostician has diagnostic information display equipment which could enable a secure diagnosis, for example. The present application discusses diagnosis authentication techniques. The primary care-giver's operator terminal (20) may challenge the diagnostic terminal (10) to certify and transmit receive various attributes useful for assuring a reasonable diagnosis.Type: ApplicationFiled: December 22, 2017Publication date: November 28, 2019Applicant: KONINKLIJKE PHILIPS N.V.Inventors: JENS VON BERG, RAVINDRA BHAT, ANAND KUMAR DOKANIA

Patent number: 10360680Abstract: A system and method are provided for obtaining an improved visualization of bone objects comprised in a projection X-ray image. The projection X-ray image comprises bone objects which at least in part overlap. According to the system and method, a number of the bone objects are delineated by a contour, thereby obtaining a number of delineated bone objects. For each of the number of delineated bone object, a bone suppression technique is applied to the image to obtain respective bone image data individually showing the respective delineated bone object while suppressing shadows of obstructing objects. The bone image data generated for each of the number of delineated bone objects is used to generate an output image in which the bone objects do not overlap. An advantage of the system and method is that a non-overlapping, shadow-suppressed, presentation of the bone objects may be created from an X-ray image which was obtained by projectional radiography.Type: GrantFiled: January 31, 2018Date of Patent: July 23, 2019Inventors: Jens von Berg, Stewart Young, Prasad Adhikarath Valappil
