Basically IGRT is IMRT with the addition of a few gold markers inserted in the prostate (fidicuals) to better guide the radiation. IMRT is the huge improvement made in EBRT in the last 20 years that allows the control of the beam in both shape and intensity.
Image-guided radiation therapy
Image-guided radiation therapy is the process of frequent two and three-dimensional imaging, during a course of radiation treatment, used to direct radiation therapy utilizing the imaging coordinates of the actual radiation treatment plan.[1] The patient is localized in the treatment room in the same position as planned from the reference

Prostate Cancer Radiation Treatments
Arun Puranik and the IGRT oncology team have been successfully treating prostate cancer patients with leading-edge radiation therapies and techniques since 1985. Effective Therapies Prostate cancer is the uncontrolled growth of abnormal cells in the prostate gland that can ultimately spread to nearby tissues or organs as well as other parts of the body.

IMRT is a 3D conformal radiotherapy technique, which applies multiple beams with optimized intensity-modulated fluence distributions. The optimal modulated intensity for each beam is determined through the dose optimization process, referred to as inverse planning, incorporating dose criteria not only for the target volume but also for the neighboring organs at risk.
What is IGRT and IMRT
What is IGRT and IMRT Intensity-Modulated Radiation Therapy (IMRT) is the most technologically advanced, most precise method of external beam radiation therapy available. lmage Guided Radiation Therapy (IGRT) takes this technology one step further. lt delivers high doses of radiation dírectly to the tumor while sparing surrounding healthy tissue.
“normale Bestrahlung” und IMRT / IGRT zurück weiter Grundsätzlich werden alle Bestrahlungspläne für die Bestrahlung bösartiger Erkrankungen und eine Vielzahl von Plänen für die Bestrahlung gutartiger Erkrankungen in unserem Hause auf der Grundlage einer Computertomographie erstellt.
Intensity modulated radiotherapy (IMRT)
Intensity modulated radiotherapy (IMRT) Intensity modulated radiotherapy (IMRT) is a type of conformal radiotherapy. Conformal radiotherapy shapes the radiation beams to closely fit the area of cancer. You can have IMRT on a standard radiotherapy machine, called

何謂影像導航放射治療 (Image-Guided Radiation Therapy,它利用計算機控制的X光加速器去向惡性腫瘤或腫瘤內的特定區域發射精確的輻射劑量。IMRT可根據腫瘤的3D形狀通過調節(或控制)輻射的強度使輻射劑量更加準確。IMRT也可對腫瘤內的區域通過聚焦施加更高的輻射劑量,能精確投射高能放射線至腫瘤。
