Modelle zur kurzfristigen Planung,l treatment planning systems including measurement-based systems, Monte Carlo, pencil beam, convolution/superposition, and collapsed cone algorithms. It is also important to understand the concept of simulated annealing for the purpose of intensity-modulated radiotherapy planning.

Dosimetry of Photon Beams in Watero-axis distance (SSD/SAD), field size, depth, wedges, and other factors. SSD setups are calculated using percent depth dose (PDD)-based formulae, while SAD setups are calculated using tissue-air ratio/tissue-phantom ratio/tissue-maximum ratio (TAR/TPR/TMR)-based formulae.
