Daily On-Line Set-Up Correction in 3D-Conformal Radiotherapy: Is It Feasible?

Abstract

When used by trained therapists, ideally, portal imaging may be carried out before each fraction, requiring approximately 10% of LINAC occupation time.

Intensity-modulated extended-field chemoradiation plus simultaneous integrated boost in the pre-operative treatment of locally advanced cervical cancer: a dose-escalation study

“…two independent checks (IC1 and 2) were performed by medical and physics staff [30]; daily set-up reproducibility was checked [31]. Portal images before irradiation were acquired on virtual orthogonal beams and deviations >3 mm in the isocenter position were immediately corrected as previously described [31].…”

On the cutting edge of intensity modulated radiotherapy and simultaneous integrated boost (IMRT-SIB): The case of a patient with 8 brain metastases

“…6 Deviations larger than 3 mm in the isocenter position were immediately corrected. For quality assurance through treatment planning and delivery, two independent checks were performed by medical and physics staff, as previously described.…”

FOLFIRI-bevacizumab and concurrent low-dose radiotherapy in metastatic colorectal cancer: preliminary results of a phase I–II study

“…A daily online correction protocol of isocentre position was applied using portal imaging, with set-up correction in case of deviations .0.5 cm in any direction. 16 All stages of the treatment planning process were subjected to a systematic independent check procedure, as previously described. 17 CHT dose adjustment According to haematological toxicity, the following recommendations for dose adjustment were provided.…”
