Patient Position Monitoring System for Beam Gated Radiation Therapy of Malignancies of the Chest and Upper Abdomen

Pilot Study of a Novel Patient Position Monitoring System for Beam Gated Radiation Therapy of Malignancies of the Chest and Upper Abdomen

• Status: Not Yet Recruiting
• Phase: —
• Study type: Observational
• Enrollment: 20 (estimated)
• Sponsor: Washington University School of Medicine · Academic / Other

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.

Conditions

• Radiotherapy
• Radiotherapy, Image-Guided

Interventions

Type	Name	Description
DEVICE	Patient 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.
