Patent number: 11915426Abstract: Devices, systems, computer program products and computer implemented methods are provided for dynamically assessing a moving object from a sequence of consecutive volumetric image frames of such object, which images are timely separated by a certain time interval, by: identifying in at least one image of the sequence the object of interest; segmenting the object to identify object contour; propagating the object contour as identified to other images of the sequence; and performing dynamic analysis of the object based on the object contour as propagated.Type: GrantFiled: January 25, 2022Date of Patent: February 27, 2024Assignee: 3mensio Medical Imaging B.V.Inventors: Jan Anne Niels de Vaan, Peter Heil, Arjen Witteveen, Martijn L.

Publication number: 20240008844Abstract: Methods and systems are provided for planning a medical intervention involving an intracavity probe and an imaging dataset of a patient. A view-type is selected from a defined set of view-types. A virtual field of view of the intracavity probe corresponding to the selected view-type is determined. A virtual intracavity image is rendered for display. The virtual intracavity image is based upon the imaging dataset and the virtual field of view. The virtual field of view can be based upon segmentation of an intracavity probe path, at least one anatomical structure, or possibly user input. In embodiments, the virtual field of view can be based upon probe parameters computed in accordance with a pre-defined set of rules for the selected view-type. The probe parameters can be computed by evaluation of a cost function expressed by the pre-defined set of rules for the selected view-type. Other aspects are described and claimed.Type: ApplicationFiled: September 20, 2023Publication date: January 11, 2024Applicant: 3mensio Medical Imaging B.V.Inventors: Jan Anne Niels de Vaan, Martijn Lambertus Laurentius Chatrou

Patent number: 10192352Abstract: A method is provided for simulating two-dimensional (2D) shadow images of an object (particularly an asymmetrical object), which comprises: a) obtaining a representation of the surface of said object; b) inputting a perspective viewing direction defining a virtual path line; c) calculating intersections between the virtual path line and the surface of the object; d) calculating the distance between couples of consecutive intersections; e) calculating simulated beam intensity attenuation between such couples of consecutive intersections from an input parameter related to the attenuation coefficient of the object and the distance as calculated in d); and f) displaying the simulated beam intensity attenuation as pixel brightness in a grey or color scale in the form of a shadow image. A corresponding device, system and computer program are also disclosed.Type: GrantFiled: July 24, 2017Date of Patent: January 29, 2019Assignee: 3mensio Medical Imaging B.V.Inventors: Jan de Vaan, Peter Heil
