New techniques are described herein for providing a user-friendly interface for adjusting dose distribution values during optimization of a radiation application plan. In an embodiment, a graphical user interface is provided that provides an image of a target area for a radiation application, and a graphical overlay of a dose distribution disposed over the target area that visually represents the optimized dose distribution according to the input dose parameters. In one or more embodiments, the dose distribution may be automatically calculated from input parameters supplied by a user through the graphical user interface prior to optimization. A user (such as a clinician, radiation oncologist, or radiation therapy operator, etc.) is able to modify the visualization of the dose distribution volume during optimization via a user input device in conjunction with the graphical user interface and have the modification adjusted in real-time.

Interactive and intuitive method to shape 3D dose distribution during optimization of IMRT plans

A portal imaging device is used to determine an amount of radiation that is delivered to at least one point while administering a radiation treatment therapy to a patient. Upon detecting that the amount of radiation that is delivered to that at least one point exceeds a predetermined amount of radiation (for example, a planned amount of radiation per the radiation treatment plan), administration of radiation treatment therapy to the patient can be automatically halted.
