Real-Time Intrafraction Motion Management During Radiotherapy

Real‐time intrafraction prostate motion during linac based stereotactic radiotherapy with rectal displacement

BACKGROUND Kilovoltage Intrafraction Monitoring (KIM) is a method which determines the three-dimensional position of the prostate from two-dimensional kilovoltage (kV) projections taken during linac based radiotherapy treatment with real-time feedback. Rectal displacement devices (RDDs) allow for improved rectal dosimetry during prostate cancer treatment. This study used KIM to perform a prelim...

Real-Time Intrafraction Motion Management During Radiotherapy

Real-time intra-fraction target tracking is a technique that enables adjustment of the target radiation while it is being delivered (i.e., intra-fraction adjustments) to compensate for movement of the organ inside the body. Real-time tracking, which may or may not use radiographic images, is one of many techniques referred to as “image-guided radiotherapy” (IGRT). For this policy, realtime trac...

Prostate Intrafraction Translation Margins for Real-Time Monitoring and Correction Strategies

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 (αΣ + γσ') for situations ranging from ...
