Tomograful elicoidal permite reprezentarea în 2D sau 3D a toracelui unui pacient, cu ajutorul unui fascicul de raze X.
La cercetare au participat peste 50.000 de fumători şi foşti fumători americani, ale căror vârste erau cuprinse între 55 - 74 de ani. Voluntarii au efectuat un examen anual, timp de trei ani, fie cu ajutorul unui tomograf, fie cu ajutorul razelor X. Perioada de monitorizare a fost de cinci ani.
Cercetătorii americani au constatat că pacienţii care au fost examinaţi cu ajutorul tomografului au prezentat o probabilitate de mortalitate - din cauza cancerului pulmonar - cu 20% mai mică în raport cu pacienţii care au fost testaţi cu raze X.
Totuşi, aceste examinări medicale nu pot să prevină contractarea cancerului pulmonar.
