A medical analysis method for estimating a motion vector field of the magnitude and direction of local motion of lung tissue of a subject is described. In one embodiment a first 3D image data set of the lung and a second 3D image data set is obtained. The first and second 3D image data sets correspond to images obtained during inspiration and expiration respectively. A rigid registration is performed to align the 3D image data sets with one another. A deformable registration is performed to match the 3D image data sets with one another. A motion vector field of the magnitude and direction of local motion of lung tissue is estimated based on the deforming step. The motion vector field may be computed prior to treatment to assist with planning a treatment as well as subsequent to a treatment to gauge efficacy of a treatment. Results may be displayed to highlight.

The invention relates to a surgery assistance system for guiding a surgical instrument, in particular a camera system (2) having an endoscope (3) dependant on manual actuation of at least one function key (T1-T6) of a control element (BE). The surgical instrument (3) is fastened to an arm system (10, 12, 14) of the surgery assistance system (1) having an instrument mount (15) and at least the tip (S) of the surgical instrument (3) can be moved in a controlled manner by means of the arm system (10, 12, 14) in a Cartesian patient coordinate system (PKS), whereby at least one of the three spatial axes (x, y, z) of the Cartesian patient coordinate system (PKS) extends through the surgical opening or the trocar point (T) receiving the surgical instrument (3). Advantageously, the angle of inclination (w) of the surgical instrument (3) is determined with respect to the spatial axis (z) of the Cartesian patent coordinate system (PKS) extending through the trocar point (T) and the angle of inclination (w) so determined is compared with a predetermined set angle of inclination (w_S). When the determined angle of inclination (w) exceeds the set angle of inclination (w_S), the tip (S) of the surgical instrument (3) is guided on a semi-spherical surface (TK) which concentrically surrounds the trocar point (T) and which receives the tip (S) of the instrument (3), and when the determined angle of inclination (w) is below the set angle of inclination (w_S), the tip (S) of the surgical instrument (3) is guided along a tangent (TG) which extends through the tip (S) of the instrument (3) and which rests on the semi-spherical surface (TK).

Even when the optical axis is offset in a rigid endoscope, the actual optical axis position is measured in advance, and surgery navigation can be performed by using the actual optical axis position.

A surgery assistance system comprising 3-dimensional shape measurement means for measuring a 3-dimensional surface shape of a patient; and a rigid endoscope (11) to be inserted into the body of the patient; wherein the rigid endoscope has a position-orientation detection marker (12) measurable by the 3-dimensional shape measurement means; 3-dimensional tomographical data of the patient imaged in advance and a position relationship relating to the actual optical axis position of the rigid endoscope measured in advance are stored in the computation means; 3-dimensional tomographical data and the 3-dimensional surface shape of the patient measured by the 3-dimensional shape measurement means are aligned; the position, orientation, and optical axis of the rigid endoscope are computed on the basis of the position-orientation detection marker measured by the 3-dimensional shape measurement means and the stored actual optical axis position of the rigid endoscope; and the aligned 3-dimensional tomographical data, the optical axis of the rigid endoscope, and the intersection of the optical axis and the tissue wall are displayed.

Provided is a surgery assistance system to perform relatively fast and accurate alignment between three-dimensional surface shape data acquired by measurement using a three-dimensional surface shape scanner and three-dimensional internal shape data acquired in advance, even when the position of the patient and the surface shape of the skin of the patient change during the surgery. A surgery assistance system (1) includes a three-dimensional surface shape scanner (20) for acquiring three-dimensional surface shape data by measuring a three-dimensional surface shape of a patient (60) and a computing device (40) for processing the data from the three-dimensional surface shape scanner. The computing device stores therein three-dimensional internal shape data of the patient that is acquired in advance by measurement using a three-dimensional tomography scanner (30). The computing device has a unit that aligns the three-dimensional internal shape data and the three-dimensional surface shape data with each other by using data of a portion where a distance between a skeleton and a skin surface is small in the three-dimensional internal shape data and three-dimensional surface shape data corresponding to this portion.

The present invention relates to a mechanical system for stabilization (1) on the floor for vehicles (2) on castors (for example a surgical assistance robot used in an operating room) that can adopt two stable states, i.e. disengaged, the vehicle (2) resting on the castors (3), and activated, the vehicle (3) being immobilized on the floor, respectively. According to the invention, the stabilization system (1) comprises: feet for resting (4) on the floor, movable between a first retracted position, at a distance from the floor, and a contact position ensuring the immobilization of the vehicle (2) through mechanical friction against the floor; means for mechanically controlling (5) said supporting feet (4), said control means (5) being movable between two stable positions corresponding to the activated and disengaged states; and mechanical means for transmitting (6) the displacement of the control means (5) simultaneously to all the supporting feet (4).

An array of surgical assistance devices that may be used to provide a source of light to the surgical site; collect video or photo imaging of the surgical site; and/or provide smoke/vapor evacuation from the surgical site. The primary elements of the invention include lengths of flexible or malleable tubing or light wave guides that, through a first flexible section, may be connected to standard operating room equipment, through to a moveable base that may be positioned by the surgeon or the surgery personnel. The moveable base includes a clip structure designed to receive the tubing or wave guide conduit, and to be placed on or near the patient at or near the surgical site. The base may be provided with a moderately weighted material to facilitate the support of the surgical assistance device or may comprise a bendable ribbon or band with a securing clip. Extending from the moveable base is a malleable or bendable section of the tubing or wave guide that extends toward the surgical site to a terminal point configured with an appropriate light output, imaging lens, or evacuation flute. Additional components within the overall system facilitate the use of the devices by the surgeon for both the active surgical process and as a record keeping function of the same.
