Modern Accelerators for Radiotherapy. A Critical Review

Maciszewski W., Scharf W.

Eksploatacja i Niezawodność

2003

nr 4

4-16

The paper describes the development of the application of particle accelerators in the treatment of cancer diseases over the past fifty years. Special emphasis is put on the routine application of conventional electron accelerators delivering electron and photon beams. This is the largest group of devices for radiotherapy (over 7500 machines operating worldwide). The number of patients reaches 5 million per year. The medical electron linacs have recently undergone considerable modifications of construction, in particular the systems of radiation field shaping. Contemporary accelerators for radiotherapy are equipped with dynamic multileaf collimators (MLC) which, in conjunction with 1MRT (Intensity Modulation Radiation Therapy) technique and special system of therapy planning, assure considerably higher precision, effectiveness and quality of treatment. Recent applications of hadronic particles, such as protons and heavy ions, are mentioned in the paper, too.

Particle accelerators for industrial processing. Part 2

Scharf W., Wieszczycka W.

Eksploatacja i Niezawodność

2001

nr 4

4-14

The applications of over 1000 electron beam (EB) accelerator processors used recently worldwide span technological fields from material modification to medical sterilization and food processing. The performance level achieved by the main manufacturers is demonstrated by some selected parameters of processors in the energy range from 0.1 MeV to 10 MeV. The design of the new generation of low cost compact in-line and stand-alone accelerators is discussed.
