Inverse planning device and methods for radiation treatment
Devices and methods that allow a user to elect between performing treatment planning by inverse planning or to be accomplished by utilizing one or more parameters input that are typically associated with forward planning are described herein. The systems can be configured to produce a treatment plan in a single iteration upon initiation of treatment planning or in response to determining or receiving a target geometry. While the system may be used iteratively in an extensively interactive fashion, viable inverse plans can be generated with a single user interaction, such as a single click, or optionally with no click at all. Advantageously, the system can optionally allows a clinician to add or adjust parameters or constraints, for example in another iteration, to provide additional autonomy if desired.

wherein upon the initiation of treatment planning without any prior user input of treatment plan parameters or constraints, the system automatically generates the treatment plan utilizing inverse planning; and
wherein upon initiation of treatment planning after user input of one or more treatment plan parameters or constraints, the system automatically generates the treatment plan utilizing, at least in part, forward planning based on the one or more treatment plan parameters or constraints previously input;
