I-Medical Physics

Umnyango uhlinzeka ngezinga eliphezulu kakhulu, izinsizakalo eziqinisekisiwe zekhwalithi ukuze kufezwe umgomo ohlukahlukene wokuthola ukuxilongwa okunembile kanye nokwelashwa okuphephile, okunembayo nangempumelelo kwesiguli kusetshenziswa imisebe.

Umnyango uhlelelwe ukuhlinzeka ngenkonzo eyingqayizivele, eklanyelwe izidingo zesiguli ngasinye, ngokusebenzisa indlela yesayensi esekelwe ebufakazini, izivumelwano ezimisiwe, imfundo kanye nocwaningo olusha. Umnyango ubheka ukuthotshelwa kwemithetho yokusetshenziswa kwemisebe ye-ionizing eminyangweni eyahlukene esibhedlela.

Ukulethwa kokwelashwa kwezokwelapha kuhlanganisa: i-chemotherapy, i-hormone therapy, i-target therapy, i-biological therapy kanye ne-immunotherapy. Isetshenziswa ngokuyinhloko kuzimo ezilandelayo:

• Uzakwethu ngesikhathi esisodwa ku-radiotherapy ukwandisa ukusebenza kahle kwemisebe.
• Ukwelashwa kwe-Neoadjuvant: Kunikezwe ngaphambi kokwelashwa okuqondile okungaba i-chemo-radiotherapy noma ukuhlinzwa. Lokhu kunikezwa futhi ukwenza imidlavuza engasebenzi
  ukusebenza ngokunciphisa usayizi kwezinye iziguli.
• I-Adjuvant Therapy: Lokhu kunikezwa ngemva kokuhlinzwa ukuze kwehliswe ingozi yokuphinda.
• I-Palliative Therapy: Ukulawula umdlavuza oseqophelweni eliphezulu (umdlavuza osusabalele ngale kwalapho usuka khona) noma umdlavuza wasendaweni ongakwazi ukuhlinzwa noma ukwelashwa nge-radiotherapy.

Ubunye bomnyango

Ithimba lokuqala eSouth-East-Asia ukugunyaza ngokomtholampilo indawo yokwelapha ye-proton yokwelapha ipensela yesimanjemanje. Ithimba lisebenzise ngempumelelo izindlela zokwelapha ze-proton zakamuva zezindawo ezihlukahlukene zemitholampilo kuhlanganise namacala ayinselele kakhulu.

Amandla omnyango alele enkonzweni ehlangene elethwa iqembu lezazi zesayensi yezokwelapha ezikhethekile ezindaweni ezithile ezinomgomo omkhulu wokunikeza ukunakekelwa okungcono kakhulu esigulini.

Iphrofayela ye-Medical Physicist

Izazi zefiziksi zezokwelapha zingochwepheshe bezempilo abanemfundo nokuqeqeshwa okukhethekile emicabangweni nasemasu okusebenzisa i-physics kwezokwelapha. Bonke ochwepheshe besayensi yezokwelapha eqenjini banesipiliyoni esinothise ekwelapheni ngemisebe okunembayo okuphezulu kanye nezindlela zokucabanga zezindlela eziningi, ukulinganisa abalingisi, ukulinganisa kanye nokuqinisekiswa kwekhwalithi yakamuva ye-radiotherapy kanye nemishini yokuxilonga kusetshenziswa izitholi ezithuthukisiwe zemisebe, ama-phantom namathuluzi.

Amalungu eqembu athole ukuqeqeshwa okukhethekile kwe-proton beam therapy ezikhungweni ezihlonishwayo emhlabeni jikelele.

Imisebenzi Yezokwelapha

Umnyango uhlinzeka ngezinsizakalo ze-medical physics eziqinisekisiwe kusukela ekuqalisweni kokuqala kuye ezinsizeni zomtholampilo zansuku zonke kanye nokuhlaziya okubucayi kuya kumakhono ahlukahlukene esibhedlela ikakhulukazi ku-Radiation Oncology, Diagnostic radiology kanye ne-Nuclear Medicine.

Ukuqalisa: Izici zokusebenza kwanoma yimiphi imishini emisha ekhiqiza imisebe, isofthiwe ehambisanayo kanye namadivayisi asekelayo kulinganiswa futhi kuhlolwa ngokucophelela ngokulandela amazinga ahlukahlukene kazwelonke nawamazwe ngamazwe kanye nezinqubo. Ukuqalisa ngempumelelo kuqinisekisa imvume evela enhlanganweni elawulayo kazwelonke kanye nokusetshenziswa okuphephile kwemishini yokwelapha iziguli. Kwa-APCC, uhlelo lwe-PROTEUS-PLUS kanye ne-RadiXact-X9 HT kanye ne-RayStation ehambisanayo (RaySearch Lab, eSweden) kanye ne-Precision (Accuray, USA) i-TPS iqashwe ukwelapha iziguli kusetshenziswa i-radiotherapy enembile kakhulu esebenzisa i-photon kanye ne-proton. Ithimba lethu liqhubeka nokuthuthukisa amasu amasha okwelapha kanye nokusetshenziswa kwezokwelapha ngemuva kokuqinisekiswa okubanzi. Ngaphandle kwalokho, ithimba liphinde laqasha imishini ehlukahlukene yokuthwebula izithombe ekhiqiza imisebe kufaka phakathi i-Aquilion-LB Wide bore CT (eToshiba, eJapan) kanye ne-Biograph Vision Digital PET-CT (eSiemens, eJalimane).

Ukulinganisa: Ososayensi bezokwelapha balinganisa futhi balinganise ukulethwa komthamo wemisebe ngemishini ehlukene ekhiqiza imisebe ngokulandela ukwenziwa kwemithetho yamazwe ngamazwe futhi baqinisekise ukuthi kulandelelwa kuze kufike ezingeni eliyinhloko.

Ukuqinisekiswa kwekhwalithi: Ukuze kuqinisekiswe ukulethwa okuphephile nokunembile komthamo wemisebe onqunyiwe esigulini, umnyango wenza ukuhlolwa kwekhwalithi okuningana okwenziwa njalo kwemishini yokulethwa kokwelashwa (i-PROTEUS-PLUS kanye ne-RadiXact-X9 HT) kanye nezingxenye ezihlobene nazo ngezikhathi zansuku zonke, zamasonto onke, zanyanga zonke kanye nezonyaka. Umnyango uphinde uqinisekise ukusebenza kahle kwemishini yokuthwebula izithombe efakwe emshinini wokwelapha we-proton/photon (ukuqinisekisa ngaphambi kokwelashwa indawo yesiguli) kanye neminye imishini yokuxilonga.

Ukuhlela ukwelashwa: Iziguli ezibhalisele noma yiluphi uhlobo lokwelashwa ngemisebe kufanele zilungiselele isinyathelo ngesinyathelo ngaphambi kokwelashwa ngemuva kwe-SOP yomnyango. Kuqala ngokulungiselela amadivayisi okuvimbela ukunyakaza aklanyelwe wena kulandelwe ukucaciswa kwesimila kanye nezitho ezibalulekile kusetshenziswa amasethi ezithombe ze-volumetric eziningi (i-CT, i-MRI, i-PET). Ukwelashwa okuhlosiwe kwenziwa ku-TPS kusetshenziswa imodeli yesiguli kanye nomshini. Ukusatshalaliswa komthamo ngaphakathi kwesiguli kubalwa kusetshenziswa ama-algorithms e-Monte-Carlo/convolution superposition ayinkimbinkimbi kakhulu futhi anembile. Uhlelo lokwelashwa olukhiqizwa ngaleyo ndlela luhlolwa yithimba le-Radiation oncologist kanye ne-Medical Physicist ukuqinisekisa ukugcwaliseka komgomo wezokwelapha ochazwe ngaphambilini.

Ukuhlela Ukwelashwa Nge-Proton: Intuthuko yezobuchwepheshe ye-PROTEUS-PLUS isenza sikwazi ukuhlela nokwelapha isiguli sethu ngendlela eyinkimbinkimbi kakhulu ye-Intensity Modulated Proton Therapy (IMPT). Ukuhlela ukwelashwa kwe-IMPT kwenziwa ku-RayStation TPS. Kuhilela ukulungiswa okuyinkimbinkimbi kokuphindaphinda kwamandla amaningi e-proton staking ngamachashazi e-proton ayizinkulungwane eziningana, izindawo zawo, isikhala kanye nesisindo ukuze kufezwe umthamo ovumelana kakhulu nesimila kanye nokusindisa izicubu ezivamile eziseduze. Samukela ukulungiswa kwe-SFO, MFO, Hybrid kanye ne-Robust kuye ngobunzima kanye nesidingo secala lomtholampilo. Ukulungiswa okuqinile kwe-4D, i-Layer kanye ne-volumetric re-painting IMPT kusetshenziselwa isimila esinamandla. I-Adaptive IMPT yenziwa njalo ezindaweni zomtholampilo ezibonisa izimpawu.

Ukuhlela Ukwelashwa nge-Photon/High Energy X-ray: Izinhlelo zokwelapha ngemisebe ye-Photon zenziwa ku-Precision TPS kusetshenziswa i-helical intensity modulated radiotherapy (IMRT) yazo zonke izindawo zemitholampilo. I-SBRT, i-frameless SRS, i-SRT kanye ne-adaptive radiotherapy nazo zenziwa njalo ezimweni ezibonisiwe. Ngaphandle kokwelapha izindawo eziningi zemitholampilo eziyinkimbinkimbi, siqale ne-Total marrow irradiation (TMI)/Total marrow and lymphoid irradiation (TMLI) okokuqala eNdiya.

Ucwaningo

Umnyango we-Medical Physics e-APCC umatasatasa nemisebenzi yocwaningo emisha ehlobene ne-imaging yezinhlobo eziningi kanye ne-radiotherapy enembayo ephezulu kusetshenziswa kokubili i-proton ne-photon beam.

Izintshisekelo zethu zamanje zocwaningo zihlanganisa, ukuthuthukiswa kwesofthiwe yangaphakathi, uphenyo lwendlela entsha yokwelapha, ubuhlakani bokwenziwa nokufunda ngomshini, ucwaningo lwe-in-vivo kanye ne-in-vitro cell-line, ukubhekana nemibuzo engaphenduliwe, idatha enkulu evela kufayela lokungena lomshini njll.

Umnyango unamaphrojekthi amaningi aqhubekayo e-intramural kanye nephrojekthi yokusebenzisana nezikhungo ezihlonishwayo eNdiya nakwamanye amazwe. Umnyango uphinde ubambe iqhaza ezivivinyweni zemitholampilo kanye namaphrojekthi ocwaningo ahlola ukulethwa kwemisebe ye-ionizing kanye ne-non-ionizing ezigulini ngezinjongo zokuxilonga kanye nokwelapha.

Umphumela wocwaningo lwethu olusha oluqhubekayo uyatholakala esigabeni Sakamuva Sokushicilela
