I-TomoTherapy

I-Tomotherapy

I-TomoTherapy System iklanyelwe ukuletha ngokuphepha nangokujwayelekile ukwelapha ngemisebe eqondiswa izithombe, i-intensity-modulated radiation (IG-IMRT) yokwelapha umdlavuza nezinye izifo. Okwenze i-TomoTherapy System yagqama uma iqhathaniswa nezinhlelo zemisebe ezivamile ukuhlanganiswa kweskena se-computed tomography (CT) ukuze senze isithombe sansuku zonke ngaphambi kwesikhathi ngasinye sokwelashwa.

Ikhono lokuthwebula nsuku zonke lenza kube nokwenzeka ngodokotela ukuthi babone futhi balungise noma yikuphi ukuhluka kokuma kwesiguli, izinguquko zesimila, noma ezinye izici, njengokuzuza isisindo noma ukuncipha, ukuze kuqinisekiswe ukulethwa okuqhubekayo okunembile nokuphephile komthamo wemisebe indawo okuhloswe ngayo. Ngenxa yokuthi ukunemba Kwesistimu ye-TomoTherapy kunciphisa ukuchayeka kwemisebe ezicutshini ezinempilo ezizungezile, odokotela abaningi babika ukuthi iziguli zabo zihlushwa yimiphumela engemihle embalwa uma kuqhathaniswa neziguli ezithola izinhlobo ezivamile zokwelapha ngemisebe.

Ukunemba kungase kuvumele i-TomoTherapy System ukuthi isetshenziselwe ukwelapha iziguli ezake zathola ukwelashwa nge-hadradiation ngaphambili uma umdlavuza wazo usubuyile kusetshenziswa ukusebenza kokwelashwa kabusha.

Kungani Ukunemba Kubalulekile?

Ukuthuthuka kwezobuchwepheshe kwenze abakhiqizi bemishini yokwelapha ngemisebe yangaphandle bakwazi ukuthuthukisa ukunemba kwezinhlelo zabo zokulethwa.

Ngenjwayelo:

• I-radiation beam idinga ukungena futhi iphume emzimbeni
• Idizayini yedivayisi ikhawulela ukuthi imishayo yemisebe ingaqondiswa kanjani emzimbeni
• Idivayisi ingase ilethe imisebe ethile kusicubu esizungeze isimila ngenxa yokunyakaza kwesimila phakathi nokwelashwa

I-Tomotherapy inikeza ukulethwa okuqhubekayo kwemisebe kusuka kumadigri angu-360 esigulini, noma ukulethwa kusuka kuma-engeli ashiwo udokotela. Lezi zici eziyingqayizivele, ezihlanganiswe nesiqondiso sesithombe se-3D sansuku zonke, zenza odokotela bakwazi ukuletha okunembe kakhulu, ukusatshalaliswa komthamo ngamunye okuhambisana ncamashi nokuma kwesimila sesiguli kuyilapho kunciphisa umthamo ube yizicubu ezivamile, ezinempilo, okuholela emiphumeleni engemihle embalwa ezigulini. Uhlelo lusiza ekwelapheni zonke izinkomba zokwelashwa ngemisebe okujwayelekile okubandakanya umdlavuza webele, wendlala yesinye, wamaphaphu, nowekhanda nentamo, ngaphezu kokwelashwa okuyinkimbinkimbi, okufana ne-total marrow irradiation.

Izinzuzo

Iziguli zihlomula kakhulu isizukulwane esisha seTomoTherapy.

• Ukuthwebula izithombe kwansuku zonke kusiza udokotela ukuthi abone ukuncipha kwesimila nsuku zonke, okubasiza ukuthi balinganisele umthamo we-tumor/cancer hhayi izicubu ezinempilo okuholela ezinkingeni ezimbalwa kanye nokulawula isimila okuphakeme kakhulu.
• Umthamo wokuthwebula we-CT ophansi nge-Iterative imaging uze usize iziguli ezinokufakwa kwensimbi okufana namazinyo okufakelwa, i-pacemaker noma izifakelo zamathambo ukuze zithole ukwelashwa okunembe kakhulu njengoba ukuthwebula kungenziwa ngaphandle kwama-artifact.
• Ukulawulwa okuphezulu kwendawo kwesimila
• Umthamo omncane wezicubu ezinempilo nezitho ezijwayelekile ze-anatomical ezifana namehlo, amaphaphu, inhliziyo, izinso, izindlala ze-parotid nezinye izitho ezifeza imisebenzi ebalulekile emzimbeni njll.
• Izinga eliphezulu lokusinda - Izinkinga ezincane noma imiphumela engemihle yokwelashwa ngemisebe
• Izinkinga ezincane noma imiphumela engemihle yokwelashwa ngemisebe
• Ukwelashwa okuhlosiwe kuba ngokoqobo
• Umthamo ukhawulelwe kulokho okuhlosiwe noma isimila
• Ukwelashwa okuyinkimbinkimbi nokwezingane kungelashwa ngokuzethemba

Usayizi wenkundla yokwelapha

Umdlavuza omkhulu ogcwele ujwayelekile ngenxa yokutholwa sekwephuzile futhi kuvame ukuthi isiguli sigcine sinethumba/ umdlavuza noma ezindaweni eziningi:

• Ngaphandle kokuhlangana kusho ukungabikho komthamo oweqayo futhi okuholela ekwelashweni okuvumelana kakhulu kanye nezinkinga ezincane nemiphumela engemihle ngenxa yomthamo omkhulu ezicutshini ezinempilo noma izitho zomzimba uma kwenzeka ukwelashwa okusekelwe i-linac.
• Izidingo zokwelashwa eziyinkimbinkimbi kakhulu ziqonde phambili futhi zinokuhamba komsebenzi okulula okusho ukunethezeka okuphezulu kwesiguli kanye nemiphumela ephakeme kakhulu

Lokhu kuyisidingo esibalulekile esifundeni njengoba iningi leziguli esifundeni ngokwemibiko lidinga ukwelashwa okukhulu ngenxa yalezi zici ezingezansi:

• Isifunda sinezinga eliphansi lokutholwa njengoba kuphela ama-20% kuya ku-30% omdlavuza atholakala eSigabeni 1 & 2.
• Lesi sifunda sinesibalo esiphezulu somdlavuza we-Prostate, H&N, Lung, Breast & GI ofinyelela ku-80-90% womdlavuza esifundeni futhi kulapho i-TomoTherapy inemiphumela yokwelapha ephakeme kakhulu.

Uhla Lwezinkomba Ezimboziwe

• I-Cancer eye yametastasized ezindaweni eziningi
• Ukwelashwa kwangaphambi kokufakelwa kwezifo zegazi, njenge-leukemia
