WebThe main constituent of our patients’ primary tumors was located in the middle third of the esophagus, whereas Patel et al 19 reported that 83.33% of patients had primary tumors in the distal third of the esophagus. We quantified the mean distal esophageal cancer motion of 0.26 cm in the LR direction, 0.29 cm in the AP direction, and 0.53 cm ... WebJul 19, 2024 · Marker-based and markerless tracking approaches focus on tracking the individual target throughout the treatment. Full anatomy algorithms monitor for intrafraction changes in the full anatomy within the field of view. Motion prediction algorithms can be used to account for the latencies due to the time for the system to localise, process and act.
