Radiotherapy with Cutting Field IMRT (CFIMRT)
To achieve the dose distribution corresponding to that in IMRT using a conventional irradiation method, we propose the combination of rectangular rotation irradiation and fixed multiport irradiation (cutting field IMRT). In this site, I will demonstrate several clinical cases and these 'templates'.
No smallsegments are used for planning by CFIMRT. So this method is different from 'conventional IMRT '. <Reference>

In comparison MLC doesn't move during irradiation at each directions and no subsegments are used in CFIMRT.

Please be sure to perform actual dose measurement in each irradiation fields in CFIMRT. And please be sure to perform comparison with the measurement dose and the calculation dose in RTPs.
