  • Patent number: 11276184
    Abstract: A method for determining the amplitude of a movement performed by a member of an articulated body comprises: obtaining a segment representative of the positioning of the member in a given reference frame at the end of said movement, generating a three-dimensional model of the member, positioned in said reference frame by means of the obtained segment, obtaining a cloud of three-dimensional points representing the member in said reference frame at the end of said movement, based on depth information provided by a sensor, said depth information defining a three-dimensional scene comprising at least a part of the articulated body including said member, repositioning the model of the member so as to minimize a predetermined error criterion between the obtained cloud of points and said model, and determining the amplitude of the movement, based on the new positioning of the model of the member.

  • Patent number: 8489173
    Abstract: A CT radiographic imaging process implements a processing operation on images in order to detect the use of a saline solution. When a saline solution is detected, it extracts a component or a portion of a component that does not appear to be contrasted in the initial images, for example, in the case of cardiac imaging, the right cavity of the heart. The imaging system comprises means for implementing this process.

  • Patent number: 8165358
    Abstract: A system and method for displaying a set of data with a virtually dissected anatomical structure. In an embodiment, the anatomical structure is a colon and various attributes of the colonic lumen are assigned a color. In an embodiment, a virtual dissection of the colon is created by mapping a three-dimensional data set to a two dimensional data set. A plurality of display index values are computed which correspond to the three-dimensional data set. Various colors are assigned to specific display index values. The three-dimensional display index values are mapped to a two-dimensional set of display index values. As directed by a user, various color cues may be displayed with the virtually dissected lumen to provide color highlights to various aspects of the colon, such as highlighting shape, fluid, or fecal presence.

  • Patent number: 8036490
    Abstract: To measure the dimensions of a tubular vessel, it is planned to plot a set of wall lines on the surface of the vessels. Then, the lengths of these wall lines are measured between a starting section and an arrival section. The plotting of the wall lines starts from a central line of the vessel divided into segments. For each central line segment, a wall line segment is defined on the wall by intersection of a plane containing this central line segment and intersecting this wall. Other wall line segments are distributed all around and all along the wall. Then, the lengths are measured.
