Te ako mō ngā Matawai CT me ngā werohanga CT

He taputapu whakaahua tātaritanga matatau ngā matawai Tomography Rorohiko (CT) e whakarato ana i ngā whakaahua whakawhiti-wāhanga taipitopito o ngā hanganga o roto o te tinana. Mā te whakamahi i ngā hihi-X me te hangarau rorohiko, ka hangaia e ēnei mīhini he whakaahua paparanga, he "poro" rānei ka taea te whakakotahi hei whakaaturanga 3D. Ka mahi te tukanga CT mā te arahi i ngā hihi hihi-X puta noa i te tinana mai i ngā koki maha. Kātahi ka kitea ēnei hihi e ngā pūoko i te taha ke, ā, ka tukatukahia ngā raraunga e te rorohiko hei whakaputa i ngā whakaahua teitei o ngā wheua, ngā kiko ngohengohe, me ngā oko toto. He mea nui te whakaahua CT mō te tātaritanga i te whānuitanga o ngā mate hauora, mai i ngā whara ki ngā mate pukupuku, nā tōna kaha ki te whakarato i ngā whakaaturanga mārama, taipitopito o te hanganga o roto.

Ka mahi ngā matawai CT mā te whakatakoto i te tūroro ki runga i tētahi tēpu motuka e neke ana ki roto i tētahi taputapu porowhita nui. I te hurihuri o te ngongo hihi-X huri noa i te tūroro, ka hopukina e ngā taputapu kite ngā hihi-X e tika ana kia puta i roto i te tinana, kātahi ka hurihia hei whakaahua mā roto i ngā rauropi rorohiko. He tere te mahi, ā, kāore e pokanoa, ā, ka oti te nuinga o ngā matawai i roto i ngā meneti. Ko ngā whanaketanga matua o te hangarau CT, pērā i te tere whakaahua tere ake me te whakaiti i te pānga o te irahiko, kei te whakapai tonu i te haumaru o te tūroro me te whai huatanga o te tātaritanga. Mā te āwhina o ngā matawai CT hou, ka taea e ngā tākuta te mahi i te angiography, te colonoscopy mariko, me te whakaahua ngākau, me ētahi atu tikanga.

Ko ngā waitohu matua o te mākete matawai CT ko GE Healthcare, Siemens Healthineers, Philips Healthcare, me Canon Medical Systems. He maha ngā tauira o ia waitohu kua hangaia hei whakatutuki i ngā hiahia haumanu rerekē, mai i te whakaahua taumira teitei ki te matawai tere o te tinana katoa. Ko te raupapa Revolution CT a GE, te raupapa SOMATOM a Siemens, te Incisive CT a Philips, me te raupapa Aquilion a Canon he kōwhiringa rongonui katoa e tuku ana i te hangarau hou. Kei te wātea ēnei mīhini hei hoko tika mai i ngā kaihanga, mā roto rānei i ngā kaihoko taputapu hauora whai mana, ā, he rerekē ngā utu i runga i te tauira, ngā āheinga whakaahua, me te rohe.

Werohanga CTs: Werohanga Takitahi CTmeWerohanga Upoko Takirua CT

He mea nui te mahi a ngā werohanga CT, tae atu ki ngā kōwhiringa Upoko-kotahi me Upoko-rua, ki te tuku i ngā matū rerekē i te wā o ngā matawai CT. Mā ēnei werohanga ka taea te whakahaere tika i te werohanga o ngā matū rerekē, ka whakarei ake i te māramatanga o ngā oko toto, ngā whekau, me ētahi atu hanganga i roto i ngā whakaahua ka puta. Ka whakamahia ngā werohanga Upoko-Kotahi mō te tuku matū rerekē māmā, ko ngā werohanga Upoko-rua ka taea te tuku i ngā matū rerekē e rua, i ngā otinga rānei i te wā kotahi, i te wā kotahi rānei, ka whakapai ake i te ngāwari o te tuku matū rerekē mō ngā whakaritenga whakaahua uaua ake.

Te mahi a tētahiPūwero CTme mātua whakahaere me te whakatū tika. I mua i te whakamahinga, me tirotiro e ngā tohunga hangarau te werohanga mō ngā tohu o te hapa, me te whakarite kia tika te utaina o te matū whakawehewehe hei karo i ngā embolism hau. He mea nui te pupuri i tētahi mara parakore huri noa i te wāhi werohanga me te whai i ngā tikanga haumaru e tika ana. Hei tāpiri, he mea nui kia aroturukihia te tūroro i te wā e werohanga ana mō ngā urupare kino ki te matū whakawehewehe. He māmā ake ngā werohanga Upoko-Kotahi, ā, he maha ngā wā e pai ake ana mō ngā matawai noa, ko ngā werohanga Upoko-Rua he pai ake mō te whakaahua matatau, ina hiahiatia te whakahaere whakawehewehe maha-wāhanga.

Ko ētahi o ngā waitohu rongonui o ngā werohanga CT ko MEDRAD (nā Bayer), Guerbet, me Nemoto, e tuku ana i ngā tauira kotahi me ngā tauira takirua-Upoko. Hei tauira, ko te werohanga MEDRAD Stellant he mea whakamahi whānuitia, ā, e mōhiotia ana mō tōna pono me tōna atanga ngāwari ki te whakamahi, ko te raupapa Dual Shot a Nemoto e tuku ana i ngā āheinga werohanga takirua-Upoko matatau. Ko ēnei werohanga ka hokona mā roto i ngā kaituku whai mana, mā roto rānei i ngā kaihanga, ā, kua hangaia kia mahi tahi me ngā waitohu matawai CT rerekē, kia pai ai te hototahi me te mahi pai mō ngā hiahia whakaahua hauora.

Mai i te tau 2019, kua whakaurua mai e LnkMed te Honor C-1101 (Werohanga CT Upoko Kotahi) me Honor C-2101 (Werohanga CT Upoko Takirua), e rua ngā hangarau aunoa i hangaia hei tautoko i ngā tikanga takitahi a te tūroro me ngā matea whakaahua kua whakaritea.

I hangaia ēnei werohanga hei whakahaere me te whakarei ake i ngā rerenga mahi CT. He tere te whakarite i roto i ēnei mō te uta i ngā rauemi rerekē me te hono i te raina tūroro, he mahi ka taea te whakaoti i roto i te iti iho i te rua meneti. Ka whakamahia e te raupapa Honor he werohanga 200-mL, ā, kei roto ko te hangarau mō te tirohanga wai tika me te tika o te werohanga, kia māmā ai te ako a ngā kaiwhakamahi me te iti noa o te whakangungu.

LnkMed'sNgā pūnaha werohanga CTHe maha ngā painga e tukuna ana mō ngā kaiwhakamahi, pērā i te whirihoranga kotahi-taahiraa mō te tere rere, te rōrahi, me te pēhanga, me te āheinga mō ngā matawai tere-rua tonu hei pupuri i te pumau o te kukū o te matū rerekē i roto i ngā matawai CT porowhita maha-wāhanga. Mā tēnei ka āwhina i te whakaatu i ngā āhuatanga uaua me te whara taipitopito. I hangaia me te whakaaro ki te pakari, he hoahoa ātete wai ngā werohanga mō te pumau me te whakaiti i te mōrearea o te turuturu. Ka whakanui ake i te pai o te rere o te mahi a ngā mana pa-mata me ngā mahi aunoa, ka iti ake te mau o te taputapu i te roanga o te wā, ka waiho hei haumitanga ōhanga.

Mō ngā tohunga hauora, mā te tauira werohanga pane-rua ka taea te werohanga i te rerekētanga me te tote i te wā kotahi i ngā ōwehenga rerekē, ka whakarei ake i te māramatanga o te whakaahua puta noa i ngā ventricles e rua. Mā tēnei āhuatanga ka whakarite i te whakahekenga taurite i waenga i ngā ventricles matau me maui, ka whakaiti i ngā mahi toi, ā, ka taea te whakaatu mārama ake i ngā uaua coronary matau me ngā ventricles i roto i te matawai kotahi, ka whakapai ake i te tika o te tātaritanga.
