A fiducial-less tracking method for radiation therapy of liver tumors by diaphragm disparity analysis part 1: simulation study using machine learning through artificial neural network

ConclusionThis simulation study shows that the diaphragm and tumor position are closely related. The developed diaphragm disparity-analysis approach, featuring tracking capability and verified with clinically acceptable errors, has the potential to replace fiducial markers for clinical application. The tracking method will be further investigated in clinical datasets from patients.
