I roto i te mara o te hanga taputapu hauora, ko te tika o te tukatuka o ngā wāhanga taputapu radiotherapy tino tika e pā tika ana ki te mahi a ngā taputapu me te pānga maimoatanga o ngā tūroro. Ko te tūāpapa nekehanga gantry tino tika a XYZT e whakawhirinaki ana ki ngā painga ahurei o ngā wāhanga granite, e whakarato ana i te taurangi pakari mō te tapahi tika, te keri me ētahi atu mahi o ngā simulators kiko tangata.
He tino pumau te whakarite kia tika te tūnga
Ko te tukatuka i ngā wāhanga o ngā taputapu radiotherapy me tino tika te tūnga, ā, ko te iti o te peka ka pā ki te tika o te whitinga o te kiko pukupuku i te wā radiotherapy. Ko ngā wāhanga granite o te papa nekehanga gantry tika XYZT, he matotoru, he ōrite te hanganga o roto, he tino pumau. Ko tōna kiato he teitei ki te 2.6-2.7g/cm³, ka taea te ātete i te pokanoa wiri o waho, ahakoa i roto i te taiao uaua o te awheawhe, engari ka whakaitihia hoki te kaha wiri o te papa neke atu i te 80%. I te tapahi me te keri i ngā simulants kiko tangata, ka whakaratohia e ngā wāhanga granite he tautoko pakari mo te papa kia tika ai te tūnga o te taputapu, te taputapu tapahi rānei, me te tika o te tūnga tae atu ki te ±0.01mm. Hei tauira, i te tukatuka i ngā rau collimator o ngā taputapu radiotherapy, ka taea te whakahaere tika i te tūnga me te āhua o ngā rau, kia taea ai te arotahi tika i ngā hihi ki te wāhi pukupuku, kia kore ai e kino ki ngā kiko hauora e karapoti ana.
Te pakari teitei hei whakatutuki i ngā hiahia o te miihini tino tika
He tino uaua ngā whakaritenga mō te pakari o ngā taputapu i roto i te tukanga tapahi me te keri i ngā tauira kiko tangata. He tino pakari ngā wāhanga karāhe, ā, he kaha pēhi tae atu ki te 200-300MPa, ka taea te tu atu i te kaha tapahi nui e whakamahia ana e te taputapu i roto i te tukanga tukatuka me te kore e kitea he rerekētanga. I te wā e keri ana i te whakatauira, ka taea e te papa te noho pumau hei ārai i te nekehanga o te tūranga keri, te peka rānei o te kōhao nā te kaha. Mō ngā wāhanga moenga maimoatanga mō te hanga taputapu radiotherapy, me keri tino tika i roto i te rauemi e whakatauira ana i te hanganga wheua tangata kia taea ai te tāuta i ngā taputapu. Ka tautokohia e ngā wāhanga karāhe o te papa nekehanga karāhe tino tika XYZT te mahi pumau o te papa, ā, ka whakahaeretia te hapa tika o te tūranga poka keri i roto i te ±0.02mm, kia taea ai e te moenga maimoatanga te whakatika tika i te tūranga o te tūroro i te wā e whakamahia ana, me te whakatutuki i ngā whakaritenga o ngā taputapu radiotherapy mō te tūnga tino tika.
Ka mau tonu te tika o te miihini i te pumau o te wera
I roto i te tukanga tukatuka i ngā wāhanga taputapu hauora, te tapahi i te wera, ngā huringa pāmahana taiao me ētahi atu āhuatanga ka pā ki te tika o te tukatuka. He tino iti te tauwehenga whānui wera o te karāhe, ko te tikanga i roto i te 5-7 ×10⁻⁶/℃, ā, he iti noa te rerekētanga o te rahi ina rerekē te pāmahana. I te tukatuka i ngā tauira kiko tangata mō te wā roa, ahakoa ka rerekē te pāmahana o te awheawhe 5-10°C nā te mahi taputapu, te hauhautanga me ētahi atu take, ka taea tonu e te papa e tautokona ana e ngā wāhanga karāhe te pupuri i te rahi pumau kia kore ai e pāngia te tika o te tapahi me te keri. Hei tauira, i roto i te tapahi tika o ngā rauemi e whakaata ana i te kiko ngohengohe tangata, ka taea te whakarite kia papatahi me te whakaoti o te mata tapahi kia tutuki ai ngā whakaritenga o te urutau pai o ngā wāhanga taputapu radiotherapy me ngā kiko tangata, me te whakapai ake i te haumaru me te whai huatanga o ngā taputapu radiotherapy.
