Comparison of spectra of signals obtained by the point navigator and CAPTURE from two representative participants. (a) and (b) are from Healthy Volunteer 3, while (c) and (d) are from Healthy Volunteer 1. The non-physiological contamination (CONTMN) introduced by the two methods was indicated by dashed arrows, while the true respiratory content (RESP) was indicated by dash-dot arrows. The contamination in the case of the point navigator is clearly more widespread and leads to severe interference with the respiratory content, especially for Healthy Volunteer 1.
