An online software/algorithm, which can generate 3d model of bone shapes from its 2d x-ray image. it is an alternative to the conventional method of building 3d models from ct scans, which has 300-1000 times more radiation than normal 2d x-ray and cost 50 times more. the application involves 3d surgery planning, implant design, surgery training etc. the algorithm has been tested with simulated as well as real x-ray images of knee joint bones, using matlab based codes. the results showed acceptable accuracy with the reconstruction time of a minute. using this method, the health risks due to ct scan radiations can be reduced along with the cost and the technology can be available to all. a demonstration web-based software is available at (orthocad.iitb.ac.in/xrayto3d/) and a next version with many more features and utility is under development. the technology can be easily scaled up in terms of more bone shapes and a safe, low cost, effective medical modeling software can be developed and marketed. the related publication will be very soon available on : international journal of computer assisted radiology and surgery with the title: 3d femur model reconstruction from biplane x-ray images: a novel method based on laplacian surface deformation for template reconfiguration a few related videos: https://www.youtube.com/watch?v=qk4h-pr0yji https://www.youtube.com/watch?v=f-lcxhz-b0e https://www.youtube.com/watch?v=-8rgudvshv4&t=15m27s
