Igama elithi "unyango lwemitha" lisenokuvakala lisoyikisa kancinci kuwe. Kodwa lunyango olubaluleke kakhulu nolunamandla xa ulwa nomhlaza. Namhlanje siza kuthetha ngolunye lonyango lwemitha olutsha, oluphambili nolukhuselekileyo. Yiyo leyo i-VMAT. Masibone ukuba yintoni, isebenza njani, kwaye zithini izibonelelo zalo.
Kalula nje, yintoni le VMAT?
I-VMAT imele iVolumetric Modulated Arc Therapy . Olu lunyango olusebenzisa imitha evela ngaphandle komzimba ukubulala iiseli zomhlaza. Kwezonyango, silubiza olu Therapy lweMisebe yangaphandle (i-EBRT).
Khawuthelekelele, ufuna ukutshabalalisa ithumba elinomhlaza emzimbeni wakho, kodwa ngaphandle kokulimaza amalungu aphilileyo nalungileyo alijikelezileyo. Kulapho ke iteknoloji ye-VMAT iba yinto ebaluleke kakhulu.
Nantsi into eyenzekayo kolu nyango:
Ngelixa ulele ebhedini yonyango, umatshini omkhulu okhupha imitha uyajikeleza ngeenxa zonke kuwe kwisangqa esinye okanye ezingaphezulu. Lo matshini awukutshayi. Kodwa njengoko ujikeleza, ujolise ngqo kumhlaza kwaye ukhupha ubungakanani obufunekayo bemitha.
Eyona nto ibalulekileyo kukuba kungabikho zinto ezine-radioactive ezifakwa emzimbeni wakho ngexesha lonyango. Ngoko ke akukho mfuneko yokukhathazeka malunga nokuba umzimba wakho uza kuba ne-radioactive ngexesha lonyango okanye emva kwalo.
I-VMAT yinguqulelo ephucukileyo yonyango lwe-IMRT (Intensity-Modulated Radiation Therapy) esele isetyenziswa. Endaweni yokusebenzisa umqadi omnye omkhulu wemitha, i-IMRT isebenzisa imiqadi emininzi emincinci ukuhambisa imitha kwithumba. Kwi-VMAT, le nkqubo yenziwa ngelixa umatshini ujikeleza rhoqo (njenge-arc), ngoko ke ixesha lonyango lifutshane kakhulu.
Zeziphi iintlobo zomhlaza ezisetyenziselwa unyango lwe-VMAT?
Ngenxa yokuchaneka kwetekhnoloji ye-VMAT, sisisombululo esifanelekileyo sokunyanga iithumba ezineemilo ezingaqhelekanga, okanye iithumba ezikufutshane nezitho ezibuthathaka ezifana nengqondo, intliziyo, okanye umqolo. Khawucinge ngethumba elikhule lijikeleze isitho esibalulekileyo. Kwimeko enjalo, i-VMAT inokunyanga umhlaza kuphela ngaphandle kokulimaza isitho esiphilileyo.
Ngezantsi zezinye zezona ntlobo zixhaphakileyo zomhlaza ezisetyenziswa kakhulu kule ndlela yonyango.
