  • Publication number: 20190032514
    Abstract: The invention relates to a wheel (35) for distributing a lubricant in a turbine engine, wherein the wheel has an axis from which an annular cavity extends, open radially towards the axis and from which first and second lubricant supply lines (43, 45) depart for various members to be lubricated. Parallel to the X axis, the annular cavity is split into at least a first and a second annular sub-cavity, which are separated by a substantially radial partition (38) and which communicate with the first and second lines (43, 45) respectively.

  • Publication number: 20180214095
    Abstract: Many medical procedures involve the implantation of an element in a vascular body. Current imaging techniques allow the positioning of such expandable elements to be checked, before and after implantation, using contrast bursts into the blood from a pigtail catheter. When the implantation of the medical device needs to be performed quickly, the pigtail catheter is pulled back briskly. This process is prone to error, because at the point of implantation, a medical professional has many other factors to consider, as well as the withdrawal of the catheter. If an implantable device traps the pigtail catheter during or after expansion, undesirable results can occur, such as having to pull sharply on the catheter to remove it, and in the process, disrupting the newly implanted device. This application discusses a technique for automatically generating a region of implantation around a medical device prior to and during implantation.

  • Publication number: 20180153489
    Abstract: The present invention relates to determining optimal C-arm angulation for heart valve positioning. In order to further improve the workflow in relation with the correct positioning of a valve prosthesis, it is described to provide (12) a 2D image of an aortic root of a heart of a patient, wherein the 2D image comprises three cusps of the heart in a visible and distinct manner. Further, 2D positions of the three cusps are indicated (14) in the 2D image. An analytical 3D model of the aortic cusp locations is provided (16), and the 3D positions of the three cusps are computed (18) based on the 2D positions and the analytical 3D model. Still further, an optimal C-arm angulation is computed (20) based on the computed 3D positions of the cusps, wherein, in the optimal C-arm angulation, the three cusps are aligned in a 2D image. The optimal C-arm angulation is then provided for further image acquisition steps.

  • Publication number: 20180055462
    Abstract: A method and device is proposed for automatic detection of an event in which a device is leaving a stable position relative to and within an anatomy. The method comprises the steps of receiving a sequence of fluoroscopic images, detecting a device in at least two of the fluoroscopic images, determining a motion field of the detected device in the sequence of fluoroscopic images, generating a sequence of integrated images by integrating the sequence of fluoroscopic images taking into consideration the motion field, determining a saliency metric based on the integrated images, identifying a landmark in the integrated images based on the saliency metric, and determining as to whether the landmark is moving relative to the device, based on a variation of the saliency metric.
