Method and apparatus to facilitate patient coaching

An apparatus configured for use in a treatment setting during an energy-exposure treatment session of a target volume in a breathing patient, the apparatus comprising:

• a lighting system capable of providing a first illumination in the treatment setting that corresponds to a first light modulation, a second illumination in the treatment setting that corresponds to a second light modulation, and a third illumination in the treatment setting that corresponds to a third light modulation, wherein the first, second, and third light modulations are all different from one another;
• a control circuit operably coupled to the lighting system, the control circuit configured to:
• use the lighting system to present to the breathing patient the first illumination to indicate to the breathing patient when normal breathing is presently allowed during the energy-exposure treatment session;
• use the lighting system to present to the breathing patient the second illumination to indicate to the breathing patient that controlled breathing is presently required during the energy-exposure treatment session;
• use the lighting system to present to the breathing patient the third illumination to indicate that normal breathing will soon conclude and that controlled breathing will soon begin.
