Abstract
Reversibly switchable photoacoustic tomography (RS-PAT), a photoacoustic technique with enhanced sensitivity and resolution, is disclosed. RS-PAT utilizes a subtractive process for the formation of a photoacoustic image of a region containing a plurality of switchable photoacoustic probes. In various aspects, the photoacoustic detection in RS-PAT imaging occurs minimally twice: a first image obtained when the photoacoustic probe is in active (absorbing or ON) state and a second image obtained when the photoacoustic probe is in an inactive (less-absorbing or OFF) state. Subtraction of the second image from the first image is used to obtain the RS-PAT image.
