Gross patient error detection via cine transmission dosimetry

  title={Gross patient error detection via cine transmission dosimetry},
  author={N. P. Dang and Victor G. L. Alves and Mahmoud Ahmed and Jeffrey V. Siebers},
Purpose: To quantify the effectiveness of EPID-based cine transmission dosimetry to detect gross patient anatomic errors. Method and Materials: EPID image frames resulting from fluence transmitted through multiple patients anatomies are simulated for ~100 msec delivery intervals for hypothetical 6 MV VMAT deliveries. Frames simulated through 10 head-and-neck CTs and 19 prostate CTs with and without 1-3 mm shift and 1-3 degree rotations were used to quantify expected in-tolerance clinical setup…

Gantry-angle resolved VMAT pretreatment verification using EPID image prediction.

The method provides a comprehensive and highly efficient pretreatment verification of VMAT delivery using EPID and assesses dose delivery accuracy as a function of gantry angle to ensure accurate treatment.

A system for EPID-based real-time treatment delivery verification during dynamic IMRT treatment.

A real-time radiation delivery verification system for dynamic IMRT has been demonstrated that is designed to prevent major mistreatments in modern radiation therapy.

Time dependent pre-treatment EPID dosimetry for standard and FFF VMAT

This work shows EPID-based pre-treatment dose verification can be performed on a CP basis for VMAT plans and can measure pre- treatment doses for both flattened and unflattened beams in a time dependent manner which highlights deviations that are missed in integrated field verifications.

Error detection sensitivity test using complex errors on three patient-specific VMAT QA systems

EPID-based dosimetry showed the most sensitive QA tool to detect three possible scenarios, whereas Log file was the second best method, whereas Delta4 was the worst method to detectThree possible scenario errors.

Three-dimensional surface imaging for detection of intra-fraction setup variations during radiotherapy of pelvic tumors

Three-D surface imaging for patient setup monitoring highlighted remarkable mobility of patients during RT session, especially in the anterior–posterior direction (Z axis), suggesting that the initial setup control cannot not to be sufficient to guarantee treatment reproducibility, especially for long-lasting RT treatments.

A simple backprojection algorithm for 3D in vivo EPID dosimetry of IMRT treatments.

The authors conclude that their EPID dosimetry method is an accurate and fast tool for in vivo dose verification of IMRT plans in 3D, independent of the treatment planning system and provides a practical safety net for radiotherapy.

Investigation of a real-time EPID-based patient dose monitoring safety system using site-specific control limits

The EPID-based real-time error detection method for treatment verification during dynamic IMRT has been developed and tested for its performance and limitations, however improvement in system robustness is required to reduce the non-clinical sources of error detection.
