  • Publication number: 20240095925
    Abstract: A method for dimensional measurement of a vessel (100) of a subject that is a bodily fluid-conducting vessel comprising: receiving image data comprising a three-dimensional medical image containing the vessel; obtaining from the image data an image patch (130) that is a two-dimensional image containing a transverse cross-section of the vessel (100); generating from the image patch (130), a set of rays (R1 to RX), wherein each ray (R1 to RX) is a straight line, one end contacting a centre point (140) of the outer footprint (150) of the vessel (100) and at the other end extending beyond the outer footprint (150) of the vessel (100), wherein each ray (R1 to RX) has a different direction; determining for each ray (R1 to RX) an image intensity profile of the image patch (130) along the ray as a function of distance from the centre point (140); determining from the image intensity profile along each ray (R1 to RX), one or more of a ray wall thickness (RXwt), a ray lumen radius (RXlr), a ray outer radius (RXor); det

  • Patent number: 11109830
    Abstract: A method for determining a respiratory condition or for assessing the efficacy of a treatment for a respiratory condition or for optimizing a treatment protocol for a respiratory condition in a subject comprising the steps of: a) obtaining image data concerning two or more three-dimensional images of the subject's respiratory system, which images have been previously acquired during an assessment period; b) calculating a specific three-dimensional structural model of the subject's respiratory system for each of the two or more three-dimensional images of step a); c) comparing the three-dimensional structural models of step b) with each other to determine a respiratory condition or to assess the efficacy of a treatment for a respiratory condition or to optimize a treatment protocol for a respiratory condition.

  • Publication number: 20210068706
    Abstract: The present invention is in the field of screening techniques for pulmonary conditions. In particular, the present invention provides systems and methods for screening a subject for the presence of pulmonary conditions. A system comprises a sensor unit configured for registering an expansion of a thorax of a subject, the system being configured for determining from data outputted by the sensor unit a local expansion of the thorax and an internal airflow distribution of the lungs of the subject.

  • Patent number: 8886500
    Abstract: The disclosure relates to determining optimized parameters for mechanical ventilation comprising: obtaining data concerning a three-dimensional image of the subject's respiratory system; calculating a specific three-dimensional structural model of the subject's lung structure from the image data; calculating a specific three-dimensional structural model of the subject's airway structure from the image data; calculating a patient-specific three-dimensional structural model of the subject's lobar structure from the lung model; modeling the air flow through the airway, using the models of the airway and lobar structure of the subject at defined MV parameters; modeling the structural behavior of the airway and the interaction with the flow, using the models of the airway and lobar structure of the subject at defined MV parameters; determining the MV parameters which lead to a decrease in airway resistance and hence an increase in lobar mass flow for the same driving pressures according to the model.
