Intensity modulated radiation therapy (IMRT)

Intensity-modulated radiation therapy (IMRT) is a type of 3-dimensional external radiation therapy that uses that uses a computer to make pictures of the size and shape of the tumor. Thin beams of radiation have different intensities and are precisely aimed at the tumor from many angles. IMRT is often used to treat head and neck cancers.

IMRT can cause less damage to healthy tissue near the tumor. Dry mouth, a commonly reported side effect of traditional radiation therapy, can be less of an issue with IMRT patients.
