➔
Conventional 3D CRT treatments usually take no more than a few minutes
●
Low number of treatment beams
➔
IMRT delivery times range usually from 3 to 15 minutes BUT
depending on:
●
Machine type
●
Delivery method (SMLC, DMLC, IMAT, VMAT, …)
●
Amount of IMRT beams/segments
●
Tumor complexity (Volume, surrounding OAR, …)
●
Fraction size (hypofractionation schemes)
treatment times can increase to as long as 20 to 40 minutes
