Treatment Planning System in Radiotherapy: A Short Review.

Treatment planning is the core in radiotherapy. The present study aimed to explore the relationship between treatment planning system and radiotherapy. Some of the important steps in radiation treatment planning system have been discussed in this paper such as patient positioning, contouring, and simulation of pre-treatment. Detailed information has been acquired by the author associated with dose calculations in different conditions, techniques used in beam modification. Since ionising radiation creates ions in the cells of the tissues where it travels through, hence it has the capability to treat cancer cells. By taking away electrons from atoms and molecules, ions are created. It can therefore either eliminate the genes or inhibit their growth. The molecular processes leading to tissue damage illustrate that ionizing radiation not only globally affects biomolecules but also selectively alters various biomolecules in response to chemotherapy. Linear accelerator is abbreviated as LINAC. It produces high energy electron or X-ray beams using electricity. Although there are many applications for these beams, cancer treatment is one of them.
