Additional Information

Official title Placing Trust in Endoscopic Ultrasonography: Impact on Planning Conformal Radiotherapy of Cancer of the Esophagus and Rectum
Description The centering of radiotherapy is done with the pre-radiation scanner for tracking the implementation of target skin markers. On this scanner, it is often difficult for the radiation therapist to pinpoint the target volume. To improve the definition of the target volume, image fusion techniques with other imaging tests were developed. To improve the pre-radiotherapy identification, setting up markers echo-endoscopy has been described without major complications. The impact on targeting radiotherapy was mainly described for the prostate. The marking of digestive tumors was described by the establishment of Trustees, radiopaque markers in the lymph nodes, esophagus, stomach, pancreas, and bile ducts.
