Radiotherapy can help treat cancer in patients but it can also cause damage to healthy surrounding tissue. Tracking tumours within the body and accurately targeting them can result in less damage to patients. THis project examines how a Multileaf Collimator system could be built to accurately track and target tumours whilst minimising damage to surrounding tissue, and to construct a functioning system. In this project, we developed a low cost novel solution to minimising Multileaf Collimator systems for radiotherapy. Whilst the system was not wholly constructed, the progress does demonstrate how a miniaturised system can be built at low cost from retail components. Tracking and object recognition, motor positioning, physical construction of the system, and system communications were all demonstrated effectively. Calculations have been provided for determining an adequate motor and lead screw to drive the system, as well as future work for the project.
