extended target
2.Combining with the characteristics of the extended infrared target under the complicated circumstance, the technology of man-machine interaction into the system is performed in Chapter 3. Given a improved EFT algorithm based on the detailed analysis of the image foresting transform (LFT) algorithm.
5.Methods Ten patients with breast cancer treated by conserving-breast operation were selected to study, the region marked by silver clips with extended margin of 10 mm was defined as gross target volume (GTV) and the whole breast was delineated as the clinical target volume (CTV). Photon beam and electron beam integrated boost planning were designed respectively for every patient using ADAC Pinnacle~3 planning system and the dosimetric merits were compared.
6.Terminal defence will become most important as attack distance of the air to surface precision guided weapon is extended and guidance precision of it is improved. The importance and characteristics of terminal defence are analyzed. Primary target and weapon systems of terminal defence are summarized.
