Realization of Intensity Modulated Radiation Fields Using Multileaf Collimators

In the treatment of cancer using high energetic radiation the problem arises how to irradiate the tumor without damaging the healthy tissue in the immediate vicinity. In order to do this as efficiently as possible intensity modulated radiation therapy (IMRT) is used. A modern way to modulate the homogeneous radiation field delivered by an external accelerator is to use a multileaf collimator in...

Mini and Micro Multileaf Collimators

Multiple arc or multiple field convergent beam irradiation techniques have been used extensively for stereotactic radiosurgery (SRS) or radiotherapy (SRT) of small lesions. A major problem is that dose distributions produced by employing rectangular or circular collimators are of simple convex shape and therefore do not allow conformal treatment of irregularly shaped lesions. The use of multipl...
