IMRT
Also written as: IMRT — intensity-modulated radiation therapy
Intensity-modulated radiation therapy, an advanced technique allowing precise radiation dose sculpting around target volumes.
Full Definition
Intensity-modulated radiation therapy (IMRT) is an advanced radiotherapy technique that uses computer-controlled linear accelerators to deliver precise radiation doses that conform to three-dimensional shapes of tumors. IMRT modulates the intensity of radiation beams across the treatment field, allowing higher doses to target areas while minimizing exposure to surrounding healthy tissues. This technique enables treatment of tumors near critical structures and can reduce side effects compared to conventional radiotherapy. IMRT requires sophisticated treatment planning systems and quality assurance protocols, making it more complex than standard radiation techniques.
