THERMOACOUSTIC IMAGING METHOD AND SYSTEM AND THERMOACOUSTIC IMAGING CONTRAST AGENT

Abstract:

A thermoacoustic imaging method comprises administering a thermoacoustic imaging contrast agent to a subject, the thermoacoustic imaging contrast agent having a viscosity higher than blood and substantially similar to a viscosity of a known computed tomography (CT) or magnetic resonance imaging (MRI) contrast agent; and imaging the subject with a thermoacoustic imaging system. The thermoacoustic imaging contrast agent may comprise an ionic solution and thickening agent mixture, with an optional heating agent. The ionic salt makes 0.5% to 5.0% of the ionic solution by weight and the remainder of the ionic solution is water. The thickening agent makes 3% to 50% of the mixture by weight.
