Witryna6 lis 2024 · 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 a linear accelerator (LINAC). How does IMRT work? The LINAC has a device called a … Witryna1 cze 2001 · The nonuniform fields required by intensity-modulation radiation therapy (IMRT) can be delivered using conventional multileaf collimators (MLC) as beam modulators. In MLC-based IMRT, the nonuniform field is initially converted into an intensity map represented as a matrix of beam intensities.
