NCT ID: NCT02095236 Withdrawn - Tumor Clinical Trials

Evaluation of Intrafractional Motion of Liver Tumors Using Markers

ESMERALDA
Start date: n/a
Phase: N/A
Study type: Interventional

Radioopaque fiducial markers or electro-magnetic transponders will be implanted into or in close proximity of the tumor. During a radiotherapy treatment session image and/or signal acquisition will be performed by ultrasound, computed tomography, magnetic resonance imaging or by specialized signal detectors The data will help to characterize tumor and organ motion during one treatment session which may in fact have impact on dose distribution
