4D Cone Beam CT Reconstruction for Radiotherapy Via Motion Vector Optimization

NCT03551405 · Status: TERMINATED · Type: OBSERVATIONAL · Enrollment: 18

Last updated 2020-08-20

No results posted yet for this study

Summary

To validate a new 4D Cone Beam CT (4DCBCT) reconstruction algorithm that was developed in our research group recently in terms of its geometry and intensity accuracy through real patient studies. Dose calculation found out in this study will not be used on the subject

Conditions

Interventions

RADIATION

CBCT scan

CBCT is a standard image guidance procedure for patient setup in image-guided radiation therapy at the Department of Radiation Oncology, UTSW. Our study will deliver three additional CBCT scans to each patient in only one fraction. These additional scans will increase radiation doses to the patients, which elevate the radiation-associated risks of secondary cancer.The other risk involved in this study is a possible violation of patient confidentiality. The imaging data will be completely anonymized, since the patient related information is not needed for this study.
