IMRT
Also written as: IMRT — Intensity-Modulated Radiation Therapy
Advanced radiation delivery technique that modulates beam intensity to conform dose distribution to tumor shape.
Full Definition
Intensity-Modulated Radiation Therapy is an advanced form of external beam radiation therapy that uses computer-controlled linear accelerators to deliver precise radiation doses. The technique modulates the intensity of radiation beams across the treatment area, allowing for highly conformal dose distributions that spare nearby organs at risk while delivering therapeutic doses to the tumor.
Usage
Usage note: Always written in all capitals; do not use periods between letters.
In Context
- "The patient's head and neck cancer will be treated with IMRT to minimize salivary gland toxicity." — Treatment recommendation
