Organ motion is one of the problems on augmented reality (AR) visualization for endoscopic surgical navigation system. However, the conventional optical and magnetic trackers are not suitable for tracking of internal organ motion. Recently, a wireless magnetic tracker, which is called the Calypso 4-D localization system has been developed. Since the sensor(More)
The purpose of this work is to determine appropriate radiation therapy beam margins to account for intrafraction prostate translations for use with real-time electromagnetic position monitoring and correction strategies. Motion was measured continuously in 35 patients over 1157 fractions at 5 institutions. This data was studied using van Herk's formula of(More)
