    Abstract: An instrument carriage provides control of a surgical instrument coupled to the instrument carriage. The instrument carriage includes a control surface that is coupled to the surgical instrument to provide the control. A detection pin having a first distal end that extends from the control surface is coupled to the instrument carriage. A magnet is fixed to a proximal end of the detection pin. A carriage controller provides an indication that the surgical instrument is present on the instrument carriage when movement of the detection pin causes an output signal from a Hall effect sensor to exceed a presence threshold value that is stored in the carriage controller as part of a calibration procedure during the assembly of the instrument carriage. Surgical instrument removal may be indicated when detection pin movement causes the output signal to be less than a removal threshold value of less than the presence threshold value.

    Abstract: Apparatus and methods are described including, while an endoluminal data-acquisition device is being moved through a subject's lumen, acquiring a plurality of endoluminal data points of the lumen using the endoluminal data-acquisition device. It is determined that respective endoluminal data points correspond to respective locations along the lumen. A display is driven to display at least some of the plurality of endoluminal data points in a stack. While a second endoluminal device is inside the lumen, a current location of at least a portion of the second endoluminal device with respect to the lumen is determined. In response thereto, an image of the second endoluminal device is displayed within the stack, at a location within the stack corresponding to the current location of the second endoluminal device. Other applications are also described.

  • Patent number: 8842894
    Abstract: Tree structures corresponding to a first linear structure and a second linear structure are constructed from medical image data including the first linear structure and the second linear structure, each repeatedly branching from an origin and extending in directions away from the origin in such a manner to become wider. Each of a first root node corresponding to a root node in the first tree structure and a second root node corresponding to a root node in the second tree structure is connected to each node, based on the characteristic that each of the first and second linear structures repeatedly branches from the origin and extends in directions away from the origin in such a manner to become wider, by using, with respect to each node, a cost function that weights a cost representing a probability of connection of each of a plurality of edges connectable to each node.

  • Patent number: 8825136
    Abstract: The present invention includes a method of pre-planning a spherical fixed point stereotactic radiosurgery by obtaining an image from a patient having a target, the image comprising coordinates of the actual patient target in 3 dimensions on a first day; planning an optimal stereotactic radiosurgery using the patient's actual target using actual coordinates in 3 dimensions prior to the day of surgery by creating virtual radiosurgical coordinates and plans to maximize target exposure and minimize the patient's waiting time in radiosurgery, thereby allowing evaluation of several plans to maximize plan conformality and safety; and treating the patient based on the virtual stereotactic radiosurgery plans on a second day.

  • Patent number: 8808668
    Abstract: The present invention provides methods and compositions for modulating x-ray attenuation, where the x-ray attenuation compound can comprise a molecule having at least two conformational states, a first k-edge atom attached to the molecule at a first position, and a second k-edge atom attached to the molecule at a second position, where the molecule changes from a first conformational state to a second conformational state in response to an external stimulus. Additionally, a first interatom distance between the first k-edge atom and the second k-edge atom in the first conformational state can be within a first harmonic error of 0 to about 0.2, and a second interatom distance between the first k-edge atom and the second k-edge atom in the second conformational state can be within a second harmonic error of about 0.8 to 1.0.

  • Patent number: 8744819
    Abstract: A model-based method is described which defines a rigid transformation between two co-ordinate systems that reduces the accuracy requirements on the quality of the data-set (including, but not restricted to, the error in the acquisition process, and the number and spread of the points) measured in one of the two co-ordinate systems by identifying a set of remote correspondences that are used to bind the convergence process. The method can be used in minimal-access orthopaedic surgery to improve the accuracy of limb registration. Specific instances include femoral registration, by estimating the functional center of the hip joint in both co-ordinate systems to be co-registered, and tibial registration, using the ankle center as a distant set of paired correspondences. Accuracy can be measured in a variety of ways, including, but not restricted to, evaluating the mis-alignment between the two co-registered objects.

  • Patent number: 8721660
    Abstract: A fiducial marker system (210a-c) comprises a first unit and a second unit. The first unit is patient affixable and comprises a partly spherical inner surface having a first center point that is adapted to receive a touch probe measurement head for measuring the spatial position of the center point. The second unit is releasably attachable to an outer surface of the first unit, and has a second center point, wherein the first center point and the second center point are substantially identical when the second unit is attached to the first unit. For stereotactic therapy, a patient is imaged with the first and second unit assembled. Then the second unit is detached. A stereotactic frame (300) is attached to the first units via arms. Thus frameless imaging is provided in a frame based stereotactic surgery system with high precision. Repeated assembly of the frame (300) to the first units, remaining in the patient, provides advantageous fractionized stereotactic radiotherapy.
