The Role of Audiovisual Biofeedback on Image Quality During 4D Anatomic and Functional Imaging

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.

Primary outcomes

Measure the difference in number of artifacts on 4D CT scans using audiovisual biofeedback in comparison to Free breathing.

Time frame: Day one

The 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.
