A 0.5-V Sub-mW Wireless Magnetic Tracking Transponder
for Radiation Therapy

 

Abstract

As the position of tumor in patient moves during radiation therapy, real-time knowledge of the position of tumor is necessary in order to allow maximum amount of radiation to be focused on the tumor and minimum damage on surrounding healthy tissues. A 0.5-V sub-mW wireless active transponder for a magnetic tracking system is designed in 130-nm CMOS technology to track the position of the tumor. An error of less than 5 mm is achieved with the tracking system.
