Intensity Modulated Proton Therapy

Proton pencil beams take advantage of the charged particle bragg peakthe characteristic peak of dose at the end of rangecombined with the modulation of pencil beam. The latest generation of proton treatment methods is called intensity modulated proton therapy or impt.

In proton therapy medical personnel use a particle accelerator to target a tumor with a beam of protons.

Intensity modulated proton therapy. Radiation doses in descending order are shown as red yellow green and blue. Intensity modulated proton therapy impt is a sophisticated mode of proton therapy. Intensity modulated proton therapy impt implies the electromagnetic spatial control of well circumscribed pencil beams of protons of variable energy and intensity.

Intensity modulated proton therapy impt also known as pencil beam proton therapy is a sophisticated mode of proton therapy that is analogous to imrt and an active area of investigation in cancer care. Dosimetric studies have demonstrated the superiority of impt over imrt to improve dose sparing of organs in located in the head and neck. Multifield optimization impt allows for high quality plans that can target superficially located hncs as well as large neck volumes while.

Intensity modulated radiation therapy imrt is an advanced type of radiation therapy used to treat cancer and noncancerous tumors. Proton therapy is a type of external beam radiotherapy that uses ionizing radiation. Proton pencil beams take advantage of the charged particle bragg peakthe.

Impt lets radiation oncologists adjust the precision depth and intensity of a proton beam to the peaks and valleys of complex spiderlike tumors while avoiding healthy tissue. Intensity modulated proton therapy impt implies the electromagnetic spatial control of well circumscribed pencil beams of protons of variable energy and intensity. A new study from the university of texas md anderson proton therapy center found that the use of feeding tubes in oropharyngeal carcinoma cancer patients treated with intensity modulated proton therapy decreased by more than 50 percent compared to patients treated with intensity modulated radiation therapy.

Advanced techniques such as proton radiation therapy prt and volumetric modulated arc therapy vmat may potentially further reduce the frequency and severity of radiogenic impairment. These charged particles damage the dna of cells ultimately killing them by stopping their reproduction. We retrospectively assessed 12 hgg patients who had undergone postoperative intensity modulated proton therapy impt.

Treatment plans for intensity modulated proton therapy left and standard radiation therapy deliver the same treatment dose red to the oropharyngeal tumor but proton therapy delivers less radiation to surrounding structures. Imrt uses advanced technology to manipulate photon and proton beams of radiation to conform to the shape of a tumor.
