Image-guided radiation therapy (IGRT) ndi njira yochizira ma radiation yomwe imaphatikiza njira zojambulira za radiation therapy.Panthawi ya chithandizo cha odwala, zotupa ndi ziwalo zodziwika bwino zimatha kuyang'aniridwa mu nthawi yeniyeni, ndipo ma radiation amatha kusinthidwa panthawi yake.Zinthu zambiri, monga kuyenda kwa kupuma kwa munthu, kuyenda kwa m'mimba, kulakwitsa kwa malo a radiotherapy iliyonse, komanso kuchepa kwa chotupa chomwe mukufuna, kungayambitse kugawa kwa Mlingo weniweni wa radiotherapy kukhala wosiyana kwambiri ndi momwe amapangira mapulani a radiotherapy.IGRT ikhoza kuwongolera molondola kayendedwe ka minofu ya anatomical panthawi ya chithandizo ndi kulakwitsa kwa kusamuka pakati pa mankhwala opangira mankhwala, ndipo akhoza kusintha zochitika zachipatala mogwirizana ndi kusintha kwa thupi la wodwalayo, kotero kuti malo owala amatha "kutsata" malo omwe akuwunikira.
Ukadaulo wojambula wa Cone-beam computed tomography (CBCT) ndiukadaulo womwe umagwiritsidwa ntchito kwambiri pazithunzi zotsogozedwa ndi radiotherapy.Imagwiritsa ntchito chowunikira chachikulu cha amorphous silicon digito X-ray flat-panel detector, ndipo imatha kupeza ndikumanganso zithunzi za CT mkati mwa voliyumu inayake ndi kuzungulira kumodzi kwa gantry.Chithunzi chokonzedwanso cha 3D cha chithunzi cha CT m'bukuli chikhoza kufananizidwa ndi kufananizidwa ndi chitsanzo cha odwala cha dongosolo lokonzekera chithandizo (TPS), ndipo magawo omwe amafunika kusinthidwa ndi bedi lachipatala amawerengedwa okha.
Whale4343/3030 mndandanda wa amorphous silicon X-ray flat panel detectors paokha opangidwa ndi Haobo, okhala ndi magwiridwe antchito apakati, osapumira fumbi komanso osalowa madzi, 16MV high-energy ray protection level, ali ndi kulondola kwakukulu, chithunzi chowoneka bwino komanso mawonekedwe apamwamba. Zapamwamba, zoyenera pazochitika zogwiritsira ntchito ma accelerator monga chotupa kutanthauzira ndi radiotherapy.
