Abstract
Reirradiation of spinal metastases using an add-on double-focus micro multileaf collimator and a three partial-arc conformal avoidance technique with optimized beam weights: a planning study
Highlights
Reirradiation of spinal metastases using an add-on double-focus micro multileaf collimator and a three partial-arc conformal avoidance technique with optimized beam weights: a planning study
Radiotherapy was successfully employed for the reirradiation that allowed high dose to the target while sparing spinal cord and neighbouring organs at risk (OARs) [3,4]
The motivation of this planning study was that the above small penumbra width and low leaf leakage would facilitate a highly conformal dose to a target tumour and at the same time lowest possible dose to OARs, which was desirable for the reirradiation of spinal metastases
