IMRT is an advanced form of three-dimensional conformal radiotherapy. It is generally used for individualized irradiation of uneven target areas and for maximum preservation of surrounding normal tissues. With IMRT planning using advanced treatment planning algorithms, dose distributions suitable for the shape of the target can be achieved with a steep dose drop outside the target. In this way, while the maximum dose can be given at the target compared to conformal treatments, it is ensured that the surrounding healthy tissues receive the least dose. Because of these features, it is often used in head and neck tumors and tumors located in the pelvis region.
IMRT ni aina ya juu ya radiotherapy conformal tatu-dimensional. Kwa ujumla hutumiwa kwa ajili ya radiation ya mtu binafsi ya maeneo ya lengo isiyo sawa na kwa ajili ya uhifadhi wa juu wa tishu za kawaida zinazozunguka. Kwa mpango wa IMRT kwa kutumia algorithms za mipango ya matibabu ya hali ya juu, usambazaji wa kipimo unaofaa kwa umbo la lengo unaweza kupatikana na kushuka kwa kipimo cha juu nje ya lengo. Kwa njia hii, wakati kipimo cha juu kinaweza kutolewa kwa lengo ikilinganishwa na matibabu ya kawaida, inahakikishiwa kwamba tishu zenye afya zinazozunguka hupokea kipimo cha chini. Kwa sababu ya sifa hizo, mara nyingi hutumiwa katika uvimbe wa kichwa na shingo na uvimbe ulio katika eneo la paji la mgongo.
