Abstract

Recent technological development in radiotherapy allows to introduce new irradiation techniques implemented on the conventional accelerators and on the machines such as CyberKnife (CK). These significantly changes the philosophy of planning and execution of radiotherapy. One of the fundamental concepts in radiotherapy is to define the therapeutic dose. It can be defined in the point, at the selected isodose, as an average value, or combined with the volume. We present the case of prostate cancer patient irradiated using CK machine and classic accelerator (VMAT). The differences in dose distribution and its value are shown. The analysis indicates that the average dose in Planning Treatment Volume (PTV) is a useful parameter during comparison of the dose distributions realized on machines of different type.
