Abstract: The present disclosure relates to a method for carrying out dose delivery quality assurance for high-precision radiation treatment, in which parameters affecting a pass rate of dose delivery quality assurance can be derived through regression analysis, which is a known statistical analysis method, and a pass rate prediction model capable of predicting each parameter and the pass rate of dose delivery quality assurance can be derived, and accordingly, it can be predicted in advance whether dose delivery quality assurance will be passed according to the parameters through the above prediction model, without repeatedly carrying out dose delivery quality assurance according to a patient's treatment plan, and as a result, the efficiency of dose delivery quality assurance can be enhanced, and the time or capacity required for such quality assurance is reduced, such that radiation treatment for an actual patient can be quickly and precisely carried out.

Abstract: An apparatus and method for providing a graphic user interface which is used in a display device operated by a remote controller are provided. A graphic user interface screen includes a main information display area for displaying main information in the form in which a plurality of main elements are recursively disposed and a sub-information display area for displaying sub-information including supplementary information according to information provided on the main information display area. At least one sub-element included in a main element is operated by a direction selection signal which indicates a direction perpendicular to a disposition direction of the main elements.
