  • Patent number: 10070835
    Abstract: A device and a related mammography method employing the device are described. The device comprises an x-ray source, an x-ray detector placed under a support plate for supporting an object and arranged to detect the x-rays coming from the x-ray source after they have passed through the object, and a positioning assembly with an arm having multiple degrees of freedom which is a collaborative robot for positioning the x-ray source with respect to the support plate. A method for performing an imaging procedure, which includes placing an object of interest on the support plate; moving the x-ray source relative to the object of interest along a non-planar trajectory to avoid collision with the object; and activating the x-ray source and the x-ray detector so as to detect the x-rays coming from the x-ray source after they have passed through the object, thus obtaining a set of x-ray images.

  • Publication number: 20180168523
    Abstract: A system for imaging biopsy samples obtained from a patient includes: a radiation source; a radiation detector having a surface that defines a first imaging region, a second imaging region, and a third imaging region; and a collimator having a body defining an opening and selectively adjustable between a first imaging position and a second imaging position. The first imaging position allows radiation rays to pass from the radiation source, through the opening, and into the second imaging region while restricting the radiation rays from passing into the first imaging region when the radiation source is in a first scanning position. The second imaging position allows radiation rays to pass from the radiation source, through the opening, and into the third imaging region while restricting the radiation rays from passing into the first imaging region when the radiation source is in a second scanning position.

  • Publication number: 20170082557
    Abstract: A method of imaging biopsy samples using an x-ray system, where one or more images of an object positioned on an object support using the x-ray apparatus are acquired and communicating the one or more images to the controller, including a display and user interface. Then, displaying the one or more images on the display, defining an area on the one or more images using the user interface, communicating the coordinates of the defined area to a collimator, placing the biopsy samples within the area defined by the user, and acquiring one or more images of the biopsy samples without removing the object from the object support. A system for imaging biopsy samples including an x-ray apparatus and a work station, which includes a controller, where a user can select an area using the controller to illuminate, which corresponds to the field of view of the x-ray source.

  • Patent number: 9265587
    Abstract: A method for determining an insertion trajectory of a tool for reaching a moving target object prior to its insertion into a tissular matrix. The method comprises acquiring images of the tissular matrix, constructing a three-dimensional representation of the tissular matrix, determining coordinates of the initial position of the target object and any obstacles, and determining at least one potential trajectory of the tool from the coordinates of any obstacles and the initial position of the target object. The method further comprises simulating insertion of the tool in the tissular matrix to determine displacement of the target object during insertion of the tool up to the initial position of the target object along a potential trajectory, determining a new position of the target object based on the determined displacement, and determining the insertion trajectory for the new position of the target object.
