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

Who can join

Ages 18 and older · All sexes

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.

About the study

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.
