Method and device for efficiently irradiating a target from multiple irradiation angles in a particle therapy system
A control system is described which provides a user interface that displays a clear graphical representation of relevant data for a particle radiation therapy system (such as a pencil-beam proton therapy system) for treating multiple beam fields as efficiently as possible. The user interface allows a user to visualize a treatment session, select one or multiple beam fields to include in one or more beam applications, and dissociate beam fields previously grouped if necessary. Further embodiments extend the ability to initiate the application of the generated proton therapy beam and the grouping of beam fields to be performed remotely from the treatment room itself, and even automatically, reducing the need for manual interventions to setup between fields.
