Study Details

Brief 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 Criteria

Eligibility Criteria

Sex: All

Age: 18+

Healthy Volunteers: Not accepted

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 and Outcome Measures

Arms

Motion management system during standard of care treatment

Patients will wear the motion management system (eMotus) during their CT simulation scan and each of their radiation therapy treatments (no more than 15 fractions). CT simulation will take approximately 40 minutes and radiation treatments will take approximately 15-45 minutes depending on the patient's plan. Patients will complete questionnaires collecting feedback on the device after receiving their last fraction of treatment.

Interventions

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.

Primary outcome measure

  • Feasibility of eMotus system as defined by frequency of successfully delivered treatment fraction [ Time Frame: Enrollment to completion of radiation therapy (estimated total time is 1 month) ]
