Abstract: A graphical user interface (1000) for use in a patient treatment system. The graphical user interface (1000) permits graphical display and editing of individual treatment parameters, including machine (2, 4, 6) positions and field shapes. Multiple fields grouped sequentially as an intensity modulated field (IMG) may be viewed as a superimposed graphical composite (1020, 1022, 1024, 1026). In addition, a pictorial representation of the radiation beams (1026) incident on a particular target is provided. A graphic representation of field shape (1030) is provided; the graphics change as treatment progresses. Finally, manipulation of graphics permits editing of treatment information, while allowing immediate feedback as to the result of the change.

Abstract: A method and apparatus is presented in which a medical imagery workstation provides an end-user interface which when activated, windows and levels a whole image or a region of interest within the image utilizing the pixel values within a selection area. The method and apparatus customizes the pixel values when the entire image is selected before calculating the window and levels to produce a higher contrast, then redraws the entire image utilizing the newly calculated window and level values. The present invention provides a method and apparatus to enable an operator to define a region of interest, that when activated, the image is redrawn utilizing only the pixel values from the region of interest, maximizing the brightness and contrast of the selected.
