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

Sponsor

Washington University School of Medicine

Enrollment

20 participants

Start Date

May 20, 2026

Study Type

OBSERVATIONAL

Conditions

Radiotherapy Radiotherapy, Image-Guided

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.

Eligibility

Min Age: 18 Years

Inclusion Criteria5

Eligibility Criteria
Planning to receive a course of radiation therapy that, per the treating radiation oncologist, requires motion management at the time of CT simulation and during treatment. Types of treatments that require motion management during radiation therapy include treatments to the lung, heart, breast, and upper abdomen (pancreas, liver, adrenals). These may include either free-breathing treatments or breath-hold treatments.
At least 18 years of age.
No documented allergy to medical grade adhesives.
Able to understand and willing to sign an IRB approved written informed consent document.

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.
