Txog tam sim no feem ntau daim ntawv ntawm hluav taws xob siv rau kho mob qog noj ntshav yog ib tug high-zog photon beam. Qhov no yog los ntawm cov khoom siv hluav taws xob xws li cobalt, cesium, lossis lub tshuab hu ua linear accelerator (los yog linac, luv luv).

Ib yam li ntawd, cov hluav taws xob uas siv los kho mob qog noj ntshav yog dab tsi?

Kev kho hluav taws xob siv hluav taws xob hluav taws xob kom txo cov qog thiab tua cov qog nqaij hlav cancer (1). X-rays, gamma rays, thiab cov nqi them yog hom hluav taws xob siv rau kev kho mob qog noj ntshav.

Tsis tas li ntawd, qhov twg feem ntau yuav kho mob qog noj ntshav? Cancer cov neeg mob kuaj pom nyob rau theem ua ntej muaj feem ntau kom muaj kev phais dua li tshuaj kho mob. Kev phais, radiotherapy thiab chemotherapy yog mainstays ntawm kho mob qog noj ntshav . Thiab nws qhia tau tias feem ntau cov neeg mob kuaj mob ua ntej muaj feem ntau dua kom tau txais kev phais, thiab zam kev siv tshuaj khomob.

Ntawm no, hom hluav taws xob twg feem ntau siv rau kev kho hluav taws xob?

Kev kho hluav taws xob yog a hom ntawm mob qog noj ntshav kev kho mob uas siv kab teeb ntawm khaus zog tua cov qog nqaij hlav cancer. Kev kho hluav taws xob feem ntau siv X-rays, tab sis protons lossis lwm yam hom ntawm zog kuj tuaj yeem yog siv.

Vim li cas thiaj tuaj yeem siv cov duab gamma los kho cov neeg mob qog noj ntshav?

Gamma rays yog feem ntau siv hauv kev kho hluav taws xob/ hluav taws xob kho hluav taws xob rau kho mob qog noj ntshav . Gamma rays tau tua cov cell nyob thiab ua rau cov neeg phem qog . Cov Gamma hluav taws xob kev siv zog txo qis zuj zus nrog qhov tob ntawm kev nkag mus. Lawv ua puas rau cov qog nqaij hlav DNA 'DNA, ua rau lawv tuag lossis rov tsim dua qeeb dua.
