1. A method of imaging a test subject, comprising: providing one or more moveable sensors to sense an attribute of the test subject, the attribute having a tonal noise component and a broadband noise component; providing a rotational sensor to sense a rotational velocity of a rotational element of the test subject; moving each of the moveable sensors along a path while continuously acquiring: rotational sensor test data from the rotational sensor, the rotational sensor test data indicative of the rotational velocity of the rotational element; moveable sensor test data from the moveable sensors, the moveable sensor test data indicative of the sensed attribute; a position of each of the moveable sensors; and an orientation of each of the moveable sensors; constructing a set of transfer functions corresponding to points in space that have been visited by the moveable sensors, each of the transfer functions relating the moveable sensor test data to the rotational sensor test data; and producing a visual representation of the tonal noise component of the attribute in a region adjacent the test subject using the set of transfer functions.
