Ko te nuinga o ngā CT Ahumahi (matawai 3D) ka whakamahiaturanga mīhini granite tino tika.
He aha te Hangarau Matawai CT Ahumahi?
He mea hou tēnei hangarau ki te ao ine ine, ā, kei mua tonu te Exact Metrology i tēnei kaupapa. Mā ngā Matawai CT Ahumahi ka taea te tirotiro i ngā wāhanga o roto, me te kore e kino, e pakaru rānei. Kāore he hangarau kē atu o te ao e whai ana i tēnei momo āheinga.
Ko te tikanga o te CT ko te Computed Tomography, ā, ko te matawai CT o ngā wāhanga ahumahi e whakamahi ana i te momo hangarau kotahi me ngā mīhini matawai CT o te mara hauora – ka tangohia ngā pānui maha mai i ngā koki rerekē, ka hurihia ngā whakaahua hina CT ki ngā kapua pūwāhi 3-ahu e hangai ana ki te voxel. I muri i te whakaputanga o te kapua pūwāhi e te matawai CT, ka taea e Exact Metrology te whakaputa i tētahi mahere whakatairite CAD-ki-te-wāhanga, te ine i te rahi o te wāhanga, te hanga whakamuri rānei i te wāhanga kia rite ki ngā hiahia o ā mātou kiritaki.
Ngā Painga
- Ka whiwhi i te hanganga o roto o tētahi mea me te kore e whakangaro
- Ka whakaputa i ngā inenga ā-roto tino tika
- Ka taea te whakataurite ki te tauira tohutoro
- Kāore he rohe atarangi
- Hototahi ki ngā āhua me ngā rahi katoa
- Kāore he mahi tukatuka muri e hiahiatia ana
- Taumira tino pai
Mā te Whakamāramatanga: Tomography
He tikanga whakaputa whakaahua 3D o ngā hanganga o roto o tētahi mea totoka mā te tirotiro me te tuhi i ngā rerekētanga o ngā pānga ki te haerenga o ngā ngaru pūngao [ngā hihi-x] e pā ana, e takahi ana rānei i aua hanganga.
Tāpirihia te huānga o te rorohiko, ā, ka whiwhi koe i te CT (Tomography Rorohiko)—he whakaahua hihi-X e hangaia ai taua Whakaahua 3D e te rorohiko mai i tētahi raupapa whakaahua whakawhiti-wāhanga papatahi i hangaia i te taha o tētahi tuaka.
Ko ngā momo matawai CT e tino mōhiotia ana ko te Hauora me te Ahumahi, ā, he rerekē rawa atu. I roto i te mīhini CT hauora, hei tango i ngā whakaahua x-ray mai i ngā ahunga rerekē, ka hurihia te waeine hihi-X (te pūtake hihi me te pūoko) huri noa i te tūroro e tū ana. Mō te Matawai CT ahumahi, ka tū te waeine hihi-X, ā, ka hurihia te wahi mahi i te ara hihi.
Te Mahi ā-Roto: Whakaahua X-ray Ahumahi me te Tomography Rorohiko (CT)
Ka whakamahia e te matawai CT ahumahi te kaha o te hihi-X ki te uru ki roto i ngā mea. Mā te ngongo hihi-X te pūtake, ka haere ngā hihi-X mā roto i te mea i inehia kia tae atu ki te pūoko hihi-X. Ka puta i te hihi hihi-X āhua-kōne ngā whakaahua hihi-X e rua-ahu o te mea, ka tukatukahia e te pūoko i roto i te āhua rite ki te pūoko whakaahua i roto i te kāmera matihiko.
I roto i te tukanga tomografia, ka hangaia he rau ki te mano tini o ngā whakaahua ira-rua-ahu i roto i te raupapatanga—me te mea i inehia i roto i ngā tūranga hurihuri maha. Kei roto i te raupapatanga whakaahua mamati ka whakaputaina ngā mōhiohio 3D. Mā te whakamahi i ngā tikanga pāngarau e tika ana, ka taea te tatau i tētahi tauira rōrahi e whakaahua ana i te āhuahanga katoa me te hanganga rauemi o te wahi mahi.
