Abstract: A method of transmitting a series of 2-D images relating to a 3-D object or model between a server and a user terminal includes combining each of the 2-D images in the series of 2-D images into a single combined 2-D image, and transmitting the combined image to the user terminal.

Abstract: A method for determining one or more of selection, positioning or placement of a surgical implant, the method includes: predicting function of an impaired anatomical structure in an unimpaired condition; predicting post-operative function of the structure for one or more implants; selecting one or more of the implant, the implant position, or the implant location to improve the predicted post-operative function.

Abstract: The present invention relates to orthopaedic implants and has particular relevance to determining the placement of fixation apparatus or devices, such as screws, which are used to fix implants to the bone or bones with which the implants are to be connected. More particularly, the invention relates to a method for determining placement of a fixation apparatus for fixing an orthopaedic implant to bone, and the method comprising: selecting a plurality of fixation locations; using a bone density model to determine bone density associated with each location; and selecting a combination or permutation of the fixation locations dependent on the determined bone density.
