Unyango lwemitha ekhokelwa ngumfanekiso (IGRT) lunyango lokusasazeka ngemitha oludibanisa ubuchule bokucinga ngemitha yonyango.Ngethuba lenkqubo yonyango yezigulane, izicubu kunye nezitho eziqhelekileyo zinokujongwa ngexesha langempela, kwaye uluhlu lwe-irradiation lunokulungiswa ngexesha.Izinto ezininzi, ezinje ngentshukumo yokuphefumla komntu, ukuhamba kwesisu, impazamo yokubeka iradiotherapy nganye, kunye nokuncipha kwendawo ekujoliswe kuyo nethumba, kunokubangela ukuba ukuhanjiswa kweedosi zokwenyani zeradiotherapy kwahluke kakhulu kwezo zikuqulunqo lwezicwangciso zeradiotherapy.I-IGRT inokulawula ngokuchanekileyo ukunyakaza kwezicubu ze-anatomical ngexesha lonyango kunye nephutha lokufuduka phakathi kwonyango lwamaqhezu, kwaye inokulungelelanisa iimeko zonyango ngokuhambelanayo ngokuhambelana neenguqu kwisigxina somzimba wesigulane, ukwenzela ukuba intsimi ye-irradiation "ilandele" ngokusondeleyo indawo ekujoliswe kuyo.
Itekhnoloji yokucinga yeCone-beam computed tomography (CBCT) yeyona nto isetyenziswa kakhulu ngoku itekhnoloji ekhokelwa ngumfanekiso weradiotherapy.Isebenzisa i-silicon enkulu ye-amorphous ye-silicon yedijithali ye-X-ray ye-flat-panel detector, kwaye inokufumana kunye nokwakha kwakhona imifanekiso ye-CT ngaphakathi komthamo othile kunye nokujikeleza enye ye-gantry.Umfanekiso womfanekiso we-3D owenziwe ngokutsha womfanekiso we-CT kulo mqulu unokuthelekiswa kwaye uthelekiswe nomzekelo wesigulane wenkqubo yokucwangcisa unyango (TPS), kwaye iiparitha ezifuna ukulungiswa ngumbhede wonyango zibalwe ngokuzenzekelayo.
Uluhlu lwe-Whale4343/3030 lwe-amorphous silicon X-ray i-flat panel detectors ziphuhliswe ngokuzimeleyo kwaye ziyilwe nguHaobo, kunye nomgangatho ophakathi wefreyimu yokusebenza okuguquguqukayo, uthuli kunye nokukhusela amanzi, i-16MV inqanaba lokukhusela i-ray ephezulu, inokuchaneka okuphezulu, umfanekiso ocacileyo kunye nesisombululo somfanekiso ophezulu. Iphezulu, ilungele iimeko zesicelo se-accelerator ezifana ne-tumor localization kunye ne-radiotherapy.
