ABSTRACT

 Radiation treatment has been well established as an option in the clinical treatment and control of various diseases. Radiation treatment planning is an important step in the treatment and has the ultimate goal of prescribing a treatment régime with a radiation dose that is large enough to potentially cure or control a disease but does not cause serious complications to normal tissue. Thus the challenge in treatment planning is to deliver the maximum radiation dose to diseased tissue while minimizing exposure to normal cells. It is common in radiation treatment planning to use multiple irradiation positions to optimize the treatment however the number and orientation of the beams has been an area of ongoing investigation. Delivery of a single dose of radiation can be more damaging to healthy tissue, than the diseased tissue. Multiple radiation sources that converge to the same area, can effectively deliver, a high single dose to the diseased tissue while decreasing surrounding tissue doses. Treatment planning software is routinely used to calculate the dose delivery prior to the patient’s actual treatment. The simulation can be used to determine the overall effectiveness of the treatment plan. It is the objective of this project to evaluate the effectiveness of patient treatment plans  held at the National Radiotherapy Centre (NRC) to be compared to modified treatment plans using increased number of irradiation positions than that were originally administered.
