A method of creating 3D models to be used for cardiac interventional procedure planning. Acquisition data is obtained from a medical imaging system and cardiac image data is created in response to the acquisition data. A 3D model is created in response to the cardiac image data and three anatomical landmarks are identified on the 3D model. The 3D model is sent to an interventional system where the 3D model is in a format that can be imported and registered with the interventional system.

Systems, methods, and computer program products for analysis of vessel attributes for diagnosis, disease staging, and surgical planning are disclosed. A method for analyzing blood vessel attributes may include developing an atlas including statistical measures for at least one blood vessel attribute. The statistical measures can be developed from blood vessel image data from different individuals. Blood vessel attribute measurements can be obtained from an individual subject. The individual subject's blood vessel attribute measurements can be compared to the statistical measures in the atlas. Output may be produced indicative of a physical characteristic of the individual based on results from the comparison.

Less invasive surgical techniques for performing brain surgery are disclosed in which a dilating obturator and cannula assembly is inserted into brain tissue until the obturator tip and cannula are adjacent to the target tissue. The obturator is removed and surgery is performed through the cannula. In preferred embodiments the obturator and cannula are placed using image guidance techniques and systems to coordinate placement with pre-operative surgical planning. A stylet with associated image guidance may be inserted prior to insertion of the obturator and cannula assembly to guide insertion of the obturator and cannula assembly. Surgery preferably is performed using an endoscope partially inserted into the cannula with an image of the target tissue projected onto a monitor. Dilating obturator structures having a rounded or semi-spherical tip and/or an optical window for visualizing brain tissue during expansion are contemplated.

Systems and methods of generating updated surgical plans are described herein. In one embodiment, a method of generating an updated surgical plan can include generating a three dimensional (3D) model of a bone, generating a surgical plan based on the 3D model, in which the surgical plan can include: locations on the bone upon which to dispose a fixator and settings of struts of the fixator, disposing the fixator on the bone based on the surgical plan, and, based on data associated with the placement of the fixator disposed on the bone, generating an updated surgical plan including updated settings for the struts.

A system and method for computer-assisted joint analysis, wherein the joint elements in a three-dimensional imaging data set are segmented and then projected onto a two-dimensional or three-dimensional reference area for interference analysis and surgical planning.

The present disclosure provides a surgical planning and navigation system imports multiple medical imaging sources of the same body part for integrated display in the same coordinate. Images are converted into 3D volumes, spatially co-registering each image volume to a base anatomical image.

The invention is suitable for the mechanical technology field, and provides a surgical planning method and system for the percutaneous puncture. In order to realize the above purpose, the invention provides a surgical planning method for the percutaneous puncture. The method comprises the following steps of: A) obtaining the mechanical image data of a patient; B) according to the mechanical image data, reconstructing the three-dimensional model of the relevant organ and/ or tissue and/ or focus of the patient; and C) determining the surgical operation process of the percutaneous puncture on the three-dimensional model by a virtual puncture device. Therefore, according to the invention, a user can repeatedly carry out the skin puncture operation by the virtual puncture device so as to accurately obtain the skin puncture point, the angle and the puncture path of the patient.

A method for surgical planning is disclosed. A set of related two-dimensional (2D) anatomical images or 3D images is displayed. A plurality of anatomical landmarks are identified on the set of anatomical images. A three-dimensional (3D) representation of a parent prosthesis is scaled to match a scale of the 2D anatomical images based at least in part on a relationship between the anatomical landmarks. A 2D representation of the scaled 3D parent prosthesis is displayed on at least one of the 2D anatomical images. A system for surgical planning is also disclosed. The system has a prosthesis knowledge-based information system, a patient anatomical-based information system, a user interface, and a controller. The controller has an anatomical landmark identifier. The controller also has a prosthesis-to-anatomical-feature relator. The controller is configured to display a set of related two-dimensional (2D) anatomical images from the patient anatomical-based information system on the user interface.

An embodiment of the invention provides a navigation and location system and method adopting a neurosurgical robot. The navigation and location system comprises motion execution equipment, a spatial position sensor, a matched position marking unit and a host, wherein the host is connected with the motion execution equipment and the spatial position sensor and used for creating surgical planning on a digital graphic image, and the surgical planning contains a position positioned to a lesion part independently and precisely as well as a motion path; the spatial position sensor is used for capturing the matched position marking unit, so that the position mapping of different space coordinates systems can be finished by the host; the motion execution equipment carries surgical instruments, is used for performing independent and precise positioning on the lesion part according to a specific motion scheme generated on the basis of the position positioned to the lesion part, the motion path and the position mapping of the different space coordinates systems, and is further used for stabilizing and locking the surgical instruments and then supporting surgery.

The invention provides a visualization calculation method for a whole intracranial aneurysm interventional therapy stent implantation process, establishes a stent release expansion model, provides an effective numerical simulation method for the intracranial aneurysm interventional therapy stent implantation, and provides a visualization method used for detection, calculation and analysis of the surgical planning of intracranial aneurysm interventional therapy. The adopted technical scheme is as follows: firstly, a blood vessel centerline is utilized to implant a numerical simulation stent into the blood vessel, and an active contour model is utilized to perform stent expansion, then the distance of each two nodes of the stent is changeless through optimization, and finally hemodynamics calculation and analysis are performed, and optimal configuration for stent implantation is simulated and calculated. The image simulation method can be directly applied to three-dimensional vascular angiography tomographic images, enables the stent to keep own geometric morphological characters through optimization, and can utilize weight adjustment to enable the stent to be clung to the blood vessel wall as far as possible. The simulation process can control the stent implantation position conveniently, and better clinical application value is achieved in the surgical planning of interventional therapy.
