  • Treatment planning in a virtual environment
    Publication number: 20110107270
    Abstract: A method and apparatus for treatment planning are described. A treatment planning system provides a computer-simulated virtual environment including a virtual artifact that is a three-dimensional simulation of a patient anatomy, wherein the three-dimensional simulation is generated from one or more diagnostic images taken of the patient anatomy. The treatment planning system performs a treatment planning operation associated with the virtual artifact in response to a user interaction with the virtual environment.

  • ANGLE ADJUSTABLE BACKREST MOUNTING
    Publication number: 20100276975
    Abstract: Angle adjustable backrest made of a lightweight, durable, adjustable, backrest for ultralight manual wheelchairs. Light-weight material can include composites for a rigid backrest for promotion of healthier and functional interface. Angle adjustment can be any desired range such as a range from ?5 degree to 55 degrees (i.e. 85 degrees to 145 degree with respect to horizontal with the seat). No tools are necessary for any of the angle adjustments. The backrest has a horizontal adjustment (fore-aft) that can be any desired range such as 1 inch. The height selection depends on the length of the wheelchair frame tubes. The present invention improves the ease and simplicity of adjusting the backrest by or for the user, as well as enhances the aesthetic appearance and adds features necessary for achieving commercial readiness. The present invention can be retro fit onto a wide range for ultralight wheelchairs.

  • Wizard and template for treatment planning
    Patent number: 7611452
    Abstract: An interface is provided to a user to perform a plurality of treatment planning operations associated with the treatment plan before the treatment plan is optimized. The treatment planning operations include at least one of selecting a treatment planning parameter or inputting data corresponding to the treatment planning parameter. One or more templates containing one or more pre-defined treatment planning parameters are provided to the user to enable the user to skip performing one or more of the plurality of operations.
