sliding window technique
IMRT delivery method using continuously moving MLC leaves while the beam is on.
Full Definition
The sliding window technique is a sophisticated method for delivering intensity-modulated radiation therapy that achieves fluence modulation through continuous movement of multileaf collimator leaves while the treatment beam remains on. This approach differs from step-and-shoot delivery by eliminating beam interruptions between segments, resulting in smoother dose delivery and reduced treatment times. The sliding window technique requires precise synchronization between leaf motion, dose rate modulation, and monitor unit calculations to achieve the planned intensity patterns while maintaining delivery accuracy and efficiency.
