Problems solved by technology

At the same time, the use of traditional x-ray models has various limitations, such as the inability to correct the position of the patient's anatomy in the anatomy image
In surgical planning, it may be desirable to have target anatomy in a specific location, but when the image is created, the x-ray image is limited by the position of the patient on the x-ray table
Furthermore, conventional x-ray images cannot be manipulated to show rotated / repositioned anatomical structures or implants such as orthopedic joint prostheses in the x-ray image in order to provide guidance for surgical planning and comparison with postoperative records

Embodiment Construction

[0033] Before turning to the drawings, which illustrate these exemplary embodiments in detail, it is to be understood that the application is not to be limited to the details or methodology set forth in the description or illustrated in the drawings. It should also be understood that the terminology is used for the purpose of description only and should not be regarded as limiting.

[0034]Referring generally to the drawings, systems and methods for creating two-dimensional (2D) x-ray images are shown and described. The systems and methods described herein can generally create interactive high-quality virtual radiographs, also referred to herein as x-ray images, using patient computed tomography (CT) scans, segmented bone models, and preoperative planning for surgery. The generated x-ray images can provide a complete anteroposterior view for implant planning (or any other surgical planning). The generated x-ray images can also be used for comparison with post-operative record...

Abstract

A method of creating an image comprising providing three-dimensional image data of an anatomical structure, providing a model of a portion of the anatomical structure, and creating a target portion of the anatomical structure using information from the image data and information from the model Virtual radiographs. The method may also include representing the portion of the anatomy in a modified state, wherein the modified state is a resected, translated, rotated and / or otherwise modified portion of the anatomy. The method may also include adding a virtual image of the prosthetic device to the virtual radiograph. The virtual radiograph may be created by performing a ray casting process on the three-dimensional image data.

Description

[0001] Cross References to Related Applications [0002] The present application claims the benefit of and priority to US Application No. 13 / 948,592, filed July 23, 2013, the contents of which are hereby incorporated by reference in their entirety. Background technique [0003] The present disclosure relates generally to the field of x-ray visualization. The present disclosure relates more specifically to the creation of two-dimensional x-ray images for providing auxiliary views in surgical preparation. [0004] Medical personnel may be accustomed to using traditional x-ray images in surgical planning methods, and accordingly, it would be desirable to provide improvements for surgical planning and anatomy visualization that utilize the same type of images to the satisfaction of medical personnel. At the same time, the use of traditional x-ray models has various limitations, such as the inability to correct the position of the patient's anatomy in the anatomy image. In surgic...
