He putanga hou i roto i te maimoatanga mate pukupuku: Me ako tātou mō te hangarau VMAT? (Te Whakaora Awa Whakakotahi Volumetric)

He uaua ki te whakapuaki i te wehi me te manukanuka e pā ana ki a koe ina kitea e koe he mate pukupuku tōu, tō hoa aroha rānei. Ā, ina rongo koe mō te maimoatanga, tera pea ka nui ake tō mataku ina rongo koe mō te "whakaora irahiko". Engari kei te pai haere te pūtaiao hauora i ia rā, i ia rā. I tēnei rā ka kōrero tātou mō tētahi tikanga maimoatanga matatau, tino tere e aro ana ki ngā pūtau mate pukupuku anake, ā, ka tino whakaiti i te kino ki ngā pūtau hauora. Ko te VMAT te ingoa o tēnei.

Nā, he aha tēnei VMAT?

Ki te whakarāpopototanga, ko te VMAT he whakarāpopototanga mō te 'Volumetric Modulated Arc Therapy'. He rongoā irahiko tino matatau tēnei e whakamahia ana hei patu i ngā pūtau matepukupuku. Hei whakamārama, he momo Reo Irahiko Hiko o Waho (EBRT). Ko te tikanga, kāore he rauemi irahiko e werohia ana ki roto i tō tinana. Nō reira, kāore he take e manukanuka ai kei puta te irahiko mai i tō tinana i te wā e rongoatia ana, i muri rānei i te rongoā.

Whakaarohia, i a koe e takoto ana i te moenga, ka āta hurihuri haere tētahi mīhini nui i tō taha, e aro tonu ana ki ngā hihi irahiko, e aro ana ki te wāhi kei reira te matepukupuku. Koinei te mea e tupu ana me te hangarau VMAT.

He putanga matatau tēnei o tētahi atu tikanga maimoatanga irahiko, arā, ko te IMRT (Intensity-Modulated Radiation Therapy). I roto i te IMRT, hei utu mō te hihi nui kotahi o te irahiko, he maha ngā hihi iti o te irahiko ka tukuna ki te pukupuku i ngā kaha rerekē. Ka tino whakaitihia te kino ki ngā kiko hauora e karapoti ana i te pukupuku. I roto i te VMAT, ka puta tēnei tukanga i te wā e hurihuri tonu ana te mīhini, nō reira ka taea te mahi maimoatanga me te tino tika me te tere .

He aha ngā momo mate pukupuku e whakamahia ana te maimoatanga VMAT?

Nā te tika o te hangarau VMAT, he otinga pai tēnei mō te rongoā i ngā pukupuku matepukupuku he āhua rerekē, he tata rawa rānei ki ngā whekau nui o te tinana. Hei tauira, ka tūtohu pea tō tākuta matepukupuku i tēnei tikanga hei rongoā i tētahi matepukupuku kua tipu huri noa i tētahi whekau.

Ko te maimoatanga VMAT te mea e whakamahia whānuitia ana mō ngā momo mate pukupuku e whai ake nei.

Me pēhea te mahi a tēnei? He aha ngā mea ka tupu i mua i te maimoatanga?

He tukanga tino whakamaheretia te maimoatanga VMAT. He maha ngā mahi matua e whai wāhi ana.

1. Te Whakamahere Maimoatanga (Te Whakamahere me te Whakamātautau)

Koinei te taahiraa tino nui. Ka tangohia tuatahitia e tō tīma hauora ngā whakaahua toru-ahu (3D) o tō tinana. I te nuinga o te wā ka mahia tēnei mā te whakamahi i te matawai CT, engari i ētahi wā he matawai MRI, PET rānei. Mā ēnei whakaahua rātou e āwhina ki te whakatau i te wāhi tika o te mate pukupuku, tōna rahi, tōna āhua, me ngā whekau hauora e karapoti ana me tiaki mai i te irahiko.

Kātahi ka whai wāhi ki tētahi wā whakarite e kīia nei ko te "whakatauira". I konei,

• Ka whakanohoia koe ki te tūranga tika i runga i te tūru maimoatanga, ā, ka whakanohoia te hihi irahiko kia pā tika ki te mate pukupuku.
• Ka taea e koe te whakamahi i tētahi tohu rangitahi , i tētahi tohu tūturu rānei, pērā i tētahi moko iti, ki tō kiri hei tohu i te wāhi tuturu o te mate pukupuku.
• Ka taea hoki e koe te whakamahi i tētahi pokepokea ai, i tētahi kopare rānei i hangaia mō tō tinana kia noho tonu ai koe i te tūranga kotahi me te kore e nekeneke i te wā e rongoatia ana.

Ka roa pea tēnei tukanga whakamahere mō te rā kotahi, mō ētahi rā rānei, nā te mea me whakarite te maimoatanga kia rite ki te āhua o tō matepukupuku, mā te whakamahi i ngā hihi irahiko he iti noa iho i te pito o te pene (2.5 x 5 mirimita).

2. I te wā o te VMAT

Ka whakanohoia koe e te kaiwhakaora irahiko ki runga i te moenga maimoatanga i te tūranga kotahi i noho ai koe i te wā o te whakaritenga. Kātahi ka whakahaere ia i te mīhini e tuku ana i te irahiko, e kiia nei ko te "LINAC - Linear Accelerator", mai i tētahi rūma motuhake. Ka taea e koe te kōrero ki a ia mā te hopuoro.

Ina tīmata te maimoatanga, ka āta hurihuri te mīhini LINAC i a koe. I a ia e hurihuri ana, ka anga atu ngā hihi irahiko o ngā āhua me ngā kaha rerekē ki te pukupuku. Kāore koe e rongo i ēnei hihi irahiko, ā, kāore koe e rongo i te mamae. Ka aro turukihia e te kaiwhakaora irahiko ngā mea katoa i runga i te mata rorohiko.

Ahakoa e 20 meneti te roa o te wā maimoatanga katoa, he poto noa te wā e tukuna ana te irahiko, arā, e rua meneti pea. Ko te toenga o te wā ka pau ki te whakanoho tika i a koe.

3. I muri i te maimoatanga (I muri i te VMAT)

Kia mutu te wā maimoatanga, ka taea e koe te hoki ki te kāinga ka tīmata anō ki ō mahi o ia rā, pērā i te tikanga.

He aha ngā painga o te maimoatanga VMAT?

E rua ngā painga matua o te maimoatanga VMAT: te tika me te tere.

He pānga taha anō kei reira?

Nā te mea he iti ake te kino o te kiko hauora i te maimoatanga VMAT, he iti hoki te mōrearea o ngā pānga taha. Heoi, kāore e taea te ārai i ētahi kino ki ngā pūtau hauora. Ka rerekē te puta, te kore rānei o ngā pānga taha, me te aha hoki, i runga i te wāhanga o te tinana e rongoatia ana .

He rerekē ngā wheako o te katoa. Tērā pea ka pai ake te ahua o ētahi tāngata i muri tonu i te maimoatanga. Ko ētahi atu, tera pea ka roa pea ētahi marama ka tino ora. Pātai atu ki tō tākuta he aha ngā mea ka tumanakohia e koe i runga i tō āhua hauora.

Ka tukuna atu he wā tirotiro whai muri i tō maimoatanga. Kia mahara ki te haere ki ēnei wā tirotiro katoa. Kōrero ki tō tākuta mō ngā tohumate, ngā pānga taha rānei ka pā mai ki a koe.
