Pilot Study of a Novel Patient Position Monitoring System for Beam Gated Radiation Therapy of Malignancies of the Chest and Upper Abdomen
Summary
This study will evaluate the feasibility of using this novel patient position monitoring system for patients receiving radiation therapy to targets involving the chest or upper abdomen, as these are the most affected by respiratory motion. This motion monitoring system will be incorporated with standard of care on-board CT imaging to confirm that the respiratory position is tracking the tumor target appropriately.
Arms & interventions
- DevicePatient Position Monitoring System
The device is a motion management system for patients receiving radiation therapy. The system is composed of a disposable fiber optic sensor pad, a signal transceiver, and software to receive and display patient data. The sensor pad is applied to the patient's chest or abdomen and plugged into the signal transceiver, which provides the system's software to provide a visual respiratory trace for the treatment team.
Outcome measures
Primary
Feasibility of eMotus system as defined by frequency of successfully delivered treatment fraction
The feasibility of the eMotus fiber optic motion sensor system will be measured as the frequency of scheduled treatment fractions delivered successfully using eMotus. Success is defined as delivery of a treatment fraction in one on-table attempt without requiring the use of a secondary (backup) motion management system. Unsuccessful delivery of a treatment fraction will be defined as more than one attempt for gating without reproducible positioning, breath-hold, or surface guidance feedback such that the treatment could not be delivered with eMotus. Descriptive statistics will be collected and reported to determine the proportion of successful motion monitoring events.
Time frame: Enrollment to completion of radiation therapy (estimated total time is 1 month)
