Dose specification with 3-D dose planning (ICRU 'level 3').
The availability of constantly more sophisticated algorithms and methods for dose planning (denoted 'level 3' procedures by the ICRU) makes it possible to use accordingly more complex treatment techniques. Such procedures have the potential of reducing irradiation of organs at risk and other healthy tissue. However, they suffer from a substantially more difficult set-up of the patient and verification of the treatment. This will introduce additional sources of error, systematic as well as random, which will be of importance for dose reporting. The purpose of this paper is to point out some of these problems and to suggest a method for reporting which is the least sensitive to these 'new' sources of error.
