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.
Claims23
A method of treatment planning, comprising:
- providing, by a treatment planning system, a three-dimensional 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 images taken of the patient anatomy;
- and
- performing at least one treatment planning operation within the virtual environment, the at least one treatment planning operation comprising a contouring operation that comprises performing the following to create a three-dimensional volume of interest (VOI) contour:
- delineating a single three-dimensional volume around a three-dimensional region of the virtual artifact within the three-dimensional computer-simulated virtual environment that corresponds to at least a portion of a VOI without performing delineation within a plurality of two-dimensional slices;
- and
- generating the three-dimensional VOI contour in the three-dimensional computer-simulated virtual environment responsive to the single three-dimensional volume being delineated.
