Cancer enkawlna kawngah 3D technology hman a ni em? 3D-CRT (Three-Dimensional Conformal Radiation Therapy) chungchang hi han sawi mai ila

Mi tam tak chuan cancer tih thumal kan hriat hian kan hlau thin. Radiation therapy pawh hlauhna nasa tak kan nei bawk . "Aw, hei hian taksa peng hriselte pawh a nghawng dawn em ni?" Mahse tunlai technology hi a changkang hle. Vawiin hian special radiation treatment plan kan sawi dawn a, chu chuan cancer tumor chu chiang takin a target a , a chhehvela taksa peng hriselte tihchhiatna a tihtlem phah a ni. Chu chu 3D-CRT a ni.

He 3D-CRT hi eng nge ni?

A awlsam zawngin sawi ila, 3D-CRT hi cancer natna atana External Beam Radiation Therapy (EBRT) ruahmanna siamna atana hmanraw changkang tak a ni. Enkawlna ngei ni lovin, enkawlna tur ruahmanna a ni zawk .

Tailor pakhat hnenah dress siam turin i kal ang tih han ngaihtuah teh. I tehfung dik tak a la a, i kawr chu i fit tawk turin a siamsak thin a ni lawm ni? 3D-CRT chu chutiang chu a ni. Hetah hian radiation oncologist-te chuan i cancer tumor leh a chhehvela taksa peng hrisel tak takte chu three-dimensional (3D)-in an hmu thei a ni.

He 3D view hi hmuh theih nan hian diagnostic test atanga thlalak te chu `CT (Computed Tomography)` scan, ` MRI (Magnetic Resonance Imaging)` scan, emaw `PET ( Positron Emission Tomography )` scan te hi hman a ni. Computer software bik chuan heng thlalak te hi a zirchiang a, cancer lian leh te, a pianzia leh a awmna hmun dik tak `3D map` a siam thin.

3D-CRT hmanna tur engte nge ni?

Oncologist te hian he 3D-CRT planning method hi cancer chi hrang hrang enkawl nan an hmang thin. Hetiang hmanrua hi operation tih theih lohna hmunah chuan a pawimawh hle. Tin, operation hmaa tumor tihtlem nan (`neoadjuvant therapy`) emaw, operation hnua cancer cell la awm zawng zawng tihchhiat nan (`adjuvant therapy`) planned radiation therapy a pe bawk.

A hnuaia tarlan te hi cancer chi hrang hrang, 3D-CRT hmanna atana hman tlanglawn ber berte an ni.

Engtin nge 3D-CRT hi enkawlna ruahmannaah hman a nih?

I medical team chuan he 3D-CRT planning process hi step by step in an kalpui ang che.

1. 3D Map siam dan

Pakhatnaah chuan kan sawi tawh ang khan i CT leh MRI scan atanga thlalak lak a ni a, computer program chuan tumor chu 3D map a siam a. He map hi radiation pe chhuaktu machine (`Linear Accelerator`) ah dah a ni.

2. Simulation kalpui dan

Hei hi play atana rehearsal ang mai a ni. Treatment table-ah muttir i ni ang a, radiation therapy i dawn angin i dah ang. Hetih lai hian 3D map hmangin radiation beam awmna hmun leh angle dik tak chu hriat theih a ni ang.

3. Skin marker hnawih

Simulation neih chhung hian medical team chuan i vunah hian chhinchhiahna te tak te, dot ang chi engemaw zat an dah ang. Hengte hi chhinchhiahna te tak te (`tattoos`) te, permanent tattoo ang maia lang an ni fo thin . Hengte hi i hmuh hian hlauthawng suh. Chungte chu enkawlna apiangah radiation beam chu cancer cell awmna hmun dik takah a kal theih nan dah a ni a, millimeter khat pawh a che lo ang. Heng chhinchhiahnate hian enkawlna apiangah i taksa chu a dinhmun inangah a awm reng theih nan a pui ang che.

3D-CRT hian side effect a nei em?

Hetah hian hriatthiam tur pawimawh tak chu 3D-CRT hi ruahmanna siam dan a ni a , enkawlna a ni lo. Chuvangin 3D-CRT planning process avanga direct side effects awm lo.

Mahse, chu ruahmanna ang chuan radiation therapy pek chuan side effect engemaw zat a nei thei a ni. 3D-CRT hian tissue hrisel chhiatna nasa takin a tihtlem a, mahse chhiatna engemaw zat chu a la awm thei tho. Side effect lo awm dan hi taksa enkawl mek laiah a innghat a ni.

3D-CRTs te thatna leh tunlai technology te

3D-CRT method hian a thatna lian ber chu tumor chu chiang takin a target a, a chhehvel tissue hrisel tihchhiatna a ti tlem hle.

Mahse, tunlai hian 3D-CRT aiin radiation treatment planning method hmasawn zawk a awm ta a ni. Chumi zinga pakhat chu `Intensity-Modulated Radiation Therapy (IMRT)` tih a ni.

IMRT hian beam lian tak pakhat ai chuan beam te tak te (beamlet) tam tak, tam tak a hmang a. Beam te intensity pawh a inthlak thei bawk. Thlalak pakhat chu rawng pakhat ni lovin, paint stroke te tak te, chi hrang hrang hmanga painting ang mai a ni. Hei hian IMRT hian tumor complex shape nena inmil zawk radiation a pe thei a ni. Zirna thenkhatah chuan IMRT hian side effect a nei tlem zawk thei niin an sawi.

Radiation therapy pek i nih chuan i doctor emaw medical team emaw hnenah a kalphung zawh hreh suh. Engkim chiang taka i hriat chuan thlamuanna ropui tak a ni ang.
