Image-inotungamirwa neradiation therapy (IGRT) kurapwa nemwaranzi inosanganisa matekiniki ekufungidzira ekurapa nemwaranzi.Munguva yekurapwa kwevarwere, mapundu uye nhengo dzakajairika dzinogona kutariswa munguva chaiyo, uye irradiation range inogona kugadziriswa nenguva.Zvinhu zvakawanda, zvakaita sekufamba kwekufema kwemunhu, gastrointestinal motility, kukanganisa kwekumisikidza kweradiotherapy yega yega, uye kuderera kwebundu rakanangana nenharaunda, zvinogona kukonzera kugoverwa kweiyo chaiyo radiotherapy dosi kuti ive yakasiyana zvakanyanya neiyo mukugadzira zvirongwa zveradiotherapy.IGRT inogona kunyatso kudzora kufamba kweanatomical tishu panguva yekurapa uye kukanganisa kwekuchinja pakati pekurapa kwechikamu, uye inogona kugadzirisa mamiriro ekurapa synchronously maererano nekuchinja kwenhengo yemurwere, kuitira kuti irradiation munda unyatso "kutevera" nzvimbo inotarirwa.
Cone-beam computed tomography (CBCT) yekufungidzira tekinoroji parizvino ndiyo inonyanya kushandiswa radiotherapy mufananidzo-inotungamirwa tekinoroji.Inoshandisa yakakura-nzvimbo amorphous silicon dhijitari X-ray flat-panel detector, uye inogona kuwana uye kuvakazve CT mifananidzo mukati meimwe vhoriyamu nekutenderera kumwe kwegantry.Iyo yakagadzirwazve 3D mufananidzo wemufananidzo we CT mufananidzo muvhoriyamu iyi inogona kufananidzwa uye kuenzaniswa nemuenzaniso wemurwere wehurongwa hwekuronga kurapwa (TPS), uye maparamita anoda kugadziriswa nemubhedha wekurapa anoverengerwa otomatiki.
Iyo Whale4343/3030 yakatevedzana yeamorphous silicon X-ray flat panel detectors yakazvimiririra yakagadziridzwa uye yakagadzirwa naHaobo, ine yepakati furemu dhizaini dhizaini, inodzivirira guruva uye isingapinde mvura, 16MV yakakwirira-energy ray kudzivirira mwero, ine huchokwadi hwepamusoro, mufananidzo wakajeka uye high image resolution. Yakakwirira, yakakodzera kune accelerator application mamiriro akadai sebundu localization uye radiotherapy.
