SUMMARY
In article the new concept of planning of contact radiotherapy (CRT) of the malignant tumours is offered, which based on synthesis of methods of mathematical programming (MMP) and interactive local methods of visual optimization (ILMVO). ILMVO, as well as MMP, can be used as an independent method of planning CRT, however their synthesis allows to form more effective therapeutic doses distributions. Research is executed at support of the Russian Foundation for Basic Research (RFBR 05-01-00326).
