Lung cancer patient respiratory motion with and without audio and audiovisual biofeedback

331 four minute respiratory traces from 24 lung cancer patients collected at Virginia Commonwealth University. The protocol consisted of five breathing training sessions spaced about a week apart. Within each session the patients initially breathed without any instruction (free breathing), with audio instructions and with audio-visual biofeedback.
