Collection and usage attributes | |
| Guide for use: | Record the type of XRT used for cancer treatment. The radiotherapy type relates to the planning target volume (PTV), the imaging type, and the radiotherapy beam arrangement. Record multiple times if multiple types of XRT are used during the course of treatment. This item is only applicable to XRT. |
