Radiation therapy interactive planning

A radiation therapy system (100) includes a radiation therapy (RT) optimizer unit (102) and an interactive planning interface unit (120). The RT optimizer unit (102) receives at least one target structure and at least one organ at risk (OAR) structure segmented from the volumetric image (108) and generates an optimized RT plan (140) based on dose targets (200-204, 210-222, 320), at least one of the dose targets corresponding to each of the at least one target structure (210-222) and the at least one OAR structure (200-204). Optimizing the RT plan includes a planned radiation dose for each voxel of the volumetric image using external beam radiation therapy, where the RT optimizer unit operates iteratively. An interactive planning interface unit (120) interactively controls each of the dose targets through a control (300) displayed on a single display (126) of a display device (124), operates the RT optimizer unit to iteratively calculate a planned radiation dose according to the control, and provides visual fe
