摘要:
A registration system and method includes a configurable device (104) having one or more moveable features (122) such that movement of the moveable features can be determined relative to a reference to define a specific configuration of the configurable device. An imaging system (110) has a display on which the configurable device is viewable. A processing device (112) is configured to register the configurable device with a coordinate system of the imaging system based on the specific configuration of the configurable device.

A guidance system and method include a real-time imaging device (121) configured to intra-operatively collect image data of a target region to provide a real-time image. A target determination module (108) is configured to generate an overlay map (111) registered to the real-time image to project morphological feature information on corresponding features in the real-time image of the target region. A medical instrument (122) is provided to perform a procedure on the target region such that the at least one medical instrument is guided to a region suitable for performing an operative task based upon the overlay map.

A robotic punch system employs a robot unit (70) and a control unit (80). The robot unit (70) includes a robot (71) and an endoscopic punch (72) mounted to the robot (71). The endoscopic punch (72) includes a calibrated spatial alignment of an endoscope (73) and a punch (74). The control unit (80) commands the robot (71) for deploying the endoscopic punch (72) in executing a puncture of an anatomical tissue (92).

A shape sensing device, system and method include an interventional instrument (102) having regions of articulation to be configured to change shape during an interventional procedure. An optical fiber (202) is disposed on or about the areas of articulation in a pattern to provide an optical signal indicating an instantaneous change or current position or orientation of the instrument. A signal interpretation module (115) is configured to receive the optical signals and interpret the instantaneous change or cur rent position or orientation of the instrument.

A robot guiding system employs a robot unit (10) and a control unit (20). The robot unit (10) includes an endoscope (12) for generating an intra-operative endoscopic image (14) of a blood vessel tree within an anatomical region, and a robot (11) for moving the endoscope (12) within the anatomical region. The control unit (20) includes an endoscope controller (22) for generating an endoscopic path within the anatomical region, wherein the endoscopic path is derived from a matching of a graphical representation of the intra-operative endoscopic image (14) of the blood vessel tree to a graphical representation of a pre-operative three-dimensional image (44) of the blood vessel tree. The control unit (20) further includes a robot controller (21) for commanding the robot (11) to move the endoscope (12) within the anatomical region in accordance with the endoscopic path.
摘要:
A real-time tracking of surgical tools relative to a pre-operative surgical plan and intra-operative images involves an image-based registration and tool tracking registration. The image-based registration implements an integration of a plurality of images of an anatomical region of a body including a pre-operative scan image (31) (e.g., a 3D CT/MRI image), an intra-operative fluoroscopic image (42) (e.g., an 2D X-ray image) and an intra- operative endoscopic image (23) (e.g., an 2D arthroscopic image). The tool tracking registration implements a representation within the pre-operative scan image (31) and/or the intra-operative fluoroscopic image (42) of a tracking of one or more surgical tools within the intra-operative endoscopic image (23).
摘要:
A pre-operative stage of a distance-based position tracking method (30) involves a generation of virtual information (21) derived from a scan image (20) illustrating an anatomical region (40) of a body during a virtual navigation of a surgical tool (51) relative to a surgical path (52) within scan image (20). The virtual information (21) includes a prediction of virtual poses of surgical tool (51) relative to surgical path (52) within scan image (20) associated with measurements of a virtual distance of surgical tool (51) from an object within scan image (20). An intra-operative stage of the method (30) involves a generation of tracking information (23) derived from measurements of a physical distance of surgical tool (51) from the object within anatomical region (40) during a physical navigation of surgical tool (51) relative to surgical path (52) within anatomical region (40). The tracking information (23) includes an estimation of poses of surgical tool (51) relative to surgical path (52) within anatomical region (40) corresponding to the prediction of virtual poses of surgical tool (51) relative to surgical path (52) within scan image (20).
摘要:
A specification for a device including a set of concentric cannulas may be discovered to have an actual path different from a desired path, due to interactions between cannulas that effect net curvature of the device. The choice of particular cannulas may be corrected by performing a calculation taking into account curvature affecting properties of the individual cannulas including radius of curvature, elasticity, and moment of inertia. This calculation is preferably performed iteratively starting with a most distal cannula and iterating through the cannulas to the proximal end, accumulating net effect of curvature affecting properties.
摘要:
A method for reconstructing a surface of a three-dimensional object involves a projection of a laser spot pattern onto the surface of the three-dimensional object by a laser, and a generation of a series of endoscopic images as an endoscope is translated and/or rotated relative to the three-dimensional object. Each endoscopic image illustrates a different view of a laser spot array within the laser spot pattern as projected onto the surface of the three-dimensional object by the laser. The laser spot array may be identical to or a subset of the laser spot pattern. The method further involves a reconstruction of the surface of the three-dimensional object from a correspondence of the different views of the laser spot array as illustrated in the endoscopic images.
