A computer-implemented method of planning orthopaedic surgery comprises providing a library of templates representing orthopaedic prostheses, displaying and scaling one or more patient images such as X-ray images, allowing a user to reconfigure geometrical constructs displayed over the images to match the construct to anatomical features shown in the image; and selecting one or more templates from the library in accordance with parameters of the reconfigured constructs. The templates correspond to the orthopaedic prosthesis or prostheses which are most suitable for the patient. Hip replacement surgery can be planned using a single patient image. Knee surgery can be planned using two patient images showing different views of the anatomical features, in which case geometrical constructs for use with each view are provided. The library of templates is accessible via the Internet so as to be accessible by users in any location and readily updateable.

Exemplary systems and methods are provided by which multiple persons in remote physical locations can collaboratively interactively visualize a 3D data set substantially simultaneously. In exemplary embodiments of the present invention, there can be, for example, a main workstation and one or more remote workstations connected via a data network. A given main workstation can be, for example, an augmented reality surgical navigation system, or a 3D visualization system, and each workstation can have the same 3D data set loaded. Additionally, a given workstation can combine real-time imagining with previously obtained 3D data, such as, for example, real-time or pre-recorded video, or information such as that provided by a managed 3D ultrasound visualization system. A user at a remote workstation can perform a given diagnostic or therapeutic procedure, such as, for example, surgical navigation or fluoroscopy, or can receive instruction from another user at a main workstation where the commonly stored 3D data set is used to illustrate the lecture. A user at a main workstation can, for example, see the virtual tools used by each remote user as well as their motions, and each remote user can, for example, see the virtual tool of the main user and its respective effects on the data set at the remote workstation. For example, the remote workstation can display the main workstation's virtual tool operating on the 3D data set at the remote workstation via a virtual control panel of said local machine in the same manner as if said virtual tool was a probe associated with that remote workstation. In exemplary embodiments of the present invention each user's virtual tools can be represented by their IP address, a distinct color, and / or other differentiating designation. In exemplary embodiments of the present invention the data network can be either low or high bandwidth. In low bandwidth embodiments a 3D data set can be pre-loaded onto each user's workstation and only the motions of a main user's virtual tool and manipulations of the data set sent over the network. In high bandwidth embodiments, for example, real-time images, such as, for example, video, ultrasound or fluoroscopic images, can be also sent over the network as well.

This invention relates generally to the field of medical devices for delivering contrast media during medical diagnostic and therapeutic imaging procedures and more particularly, this invention relates to improved contrast media delivery systems and methods of use which allow adjustment of contrast media concentration and injection parameters either before or during an injection procedure to provide patient specific dosing of contrast media, thus decreasing the waste and cost of these procedures while increasing their efficiency.
