Brief summary

This study will investigate whether audiovisual biofeedback, in which visual and audio cues are used to regulate the patient's breathing, can increase the image quality of 4D CT and 4D PET scans.

Interventions

DEVICEReal time position management system

Device to monitor respiration by using optical monitoring of a marker block placed on the abdomen of the patient.

DEVICELS PET/CT

PET/CT scanner for acquiring CT and PET images (3D and 4D)

Design outcomes

Primary

MeasureTime frameDescription
Measure the difference in number of artifacts on 4D CT scans using audiovisual biofeedback in comparison to Free breathing.Day oneThe first, third, fifth seventh and ninth patients accrued to the protocol will have their free breathing studies performed first. The second, fourth, sixth, eighth and tenth patients accrued to the protocol will have their audiovisual (a/v) biofeedback studies performed first.
