WitrynaIntensity-modulated radiation therapy (IMRT) is an advanced mode of high-precision radiotherapy that uses computer-controlled linear accelerators to deliver precise radiation doses to a malignant tumor or specific areas within the tumor. IMRT allows for the radiation dose to conform more precisely to the three-dimensional (3-D) shape of the ... Witryna21 wrz 2016 · We estimated proton beam therapy to be 2.3 times more expensive than IMRT, similar to an estimate of Goitein and Jermann, 30 who estimated proton beam therapy to be 2.4 times more than the cost of IMRT. This ratio may increase as the reimbursement of IMRT decreases with time, or may stay the same as the …
